Introduction The City of Cupertino (City) is working to investigate its water system. The City is served by three different systems: one owned and managed by California Water Service Company, one owned and managed by San Jose Water Company (SJWC), and one owned by the City. The City's water system is currently being operated and maintained by SJWC. This service is part of a 25-year concession between the City and SJWC that began in 1997. The City's water system covers approximately 3.7 square miles and has nearly 60 miles of pipelines, 3 storage tanks, and just under 4,400 water services. Before the end of the concession agreement with SJWC in 2022, the City will need to gain a thorough understanding of its water system to assist them in the decision in the following business cases: • The City takes over the operations, maintenance, management and customer interactions of the water system • The City negotiates and renews the concession agreement with the lessee responsible for all operation and customer interaction responsibilities, and the City establishes a defined capital expenditure schedule for system improvements that is paid by lessee • The City negotiates and renews the concession agreement with a lessee that is responsible for all operation and customer interactions, and the City establishes a defined capital expenditure schedule for system improvements to be paid by City • The City sells the City -owned water system In an effort to help the City make an informed business decision, the City has contracted Kayuga Solution and its team (i.e., Hanson Associates, Charles Marr Consulting, MR Valuation Consulting) to perform comprehensive water system asset planning and valuation. The goal of the project is to develop an asset management plan that provides a comprehensive understanding of the current and future asset needs, asset risk profile, appropriate levels of service, cost to provide that level of service, and financial and•resource requirements to sustain the delivery of those services. The asset management plan will provide an understanding of the City's current and future infrastructure needs for the water system assets. As system conditions change in the future, a periodic re -inspection and update of this asset management plan is recommended. 1A What is an Asset Management Plan? An asset management plan is a long-range planning document that provides a framework for understanding the assets owned by the City, services it provides, risks it assumes, and financial investments it requires. Development of an asset management plan requires answers to the following questions: • What does the City own and manage? • What is the current state of the assets? • What are the immediate asset maintenance, rehabilitation, and replacement needs? • What are longer -term asset investment needs with respect to aging assets, capacity, level of service, etc.? • What is the risk associated with asset failure? • What are the appropriate levels of service? • What is required to sustain the delivery of service? o Financial requirements o Resource requirements K AYUGA () IIII[ `I 1 o Risk vs. investment analysis • What is the cost of service? An asset management plan is a living document. It is meant to grow and change with the organization and system for which it is written. With new and/or replaced assets, an asset management plan should be updated periodically to reflect the asset risk profile and continually monitor the financial plan required to sustain the delivery of services. 1,2 Key Components of an Asset Management Pia.ri The following section introduces and defines the key components and methodology used to develop the asset management plan. Asset Register The asset register establishes the data foundation of the asset management plan by consolidating and documenting all assets owned and managed. The development of the asset register required establishing the following key elements: • Asset Definition — Helps to define what is an asset versus what is not an asset. With the asset definition established, the City is able to separate assets from components and manage them accordingly. • Asset Hierarchy— Organizes the thousands of assets in the asset register. With the asset hierarchy, the City is able to easily find assets and support asset management decisions at any level within the asset hierarchy. • Asset Classes — Groups the assets to allow the City to characterize the life -cycle behavior of the assets in the register. An asset class is developed by grouping assets with similar characteristics, such as type, function, useful life, material, and size. Asset classes are used to help model the life -cycle costs of the assets. • Asset Data Standards — Identifies the data attributes required to support asset management decisions. Asset Definition An asset was established as something that is owned and managed by the City, has a value, and is critical for the delivery of water distribution services. An asset is identified at a level at which a work order is typically generated. The initial step in developing an asset register was to consolidate all previously existing asset data in the various information systems (e.g., Geographic Information System (GIS), Excel spreadsheets, engineering drawings). Once the data was consolidated, a data gap analysis was performed to determine which assets or asset attributes (e.g., size, material) were missing. This data gap analysis provided the foundation for the data collection and correction part of the project. The data gap was filled by visiting the assets and collecting missing assets and missing attributes. Asset Class Assets are grouped into classes to more efficiently model and manage the assets. An asset class generally refers to a group of assets that behave similarly. Grouping the assets into these classes allows easier modeling of life -cycle behavior. The following table lists the City's asset classes.

General condition assessment (e.g., visual, touch, sound) was performed for accessible assets. For inaccessible assets, condition was estimated based on age. No forensic or detailed condition assessment work was involved. A condition scale of 1 to 5 (Table 1-2) was utilized to represent the general condition of the asset. Compared to a more complex scale (e.g., 1 to 10, 1 to 100), this simple scale greatly limits the subjectivity associated with the assessment of the condition score from one inspector to another. Table 1-2 Condition Assessment Score and Description 1 Excellent: New or nearly new 2 ( Very Good: Not new, but in very good condition 3 Good: Good or as expected based on age 4 Poor: Poor or recommended replacement in near -term 5 Failed/Critical: Failed or nearing failure, needs immediate attention In many cases where the asset was not visible (e.g., buried assets) or the condition could not be determined (e.g., pipes, electrical), age was used as the main indicator of the condition of the asset. Utilizing age and decay curve, the condition of an asset is estimated. The figure below illustrates the various decay curves available to represent the deterioration of assets. It is expected that decaying characteristics of most assets can best be represented by an exponential curve. Kayuga utilized the Late Decay (1.5) curve to estimate asset condition in the City's asset management plan. This curve is widely used by many utilities and municipalities in this geographic area (i.e., Santa Clara Valley Water District, City of Livermore) as it represents a more conservative view of an asset's decay. For example, a linear decay curve of an asset with a condition rating of 3 is estimated to have 63% life consumed. The same asset with the same condition utilizing the Late Decay (2) curve is estimated to have 78% life consumed.

Under limited resources, the City should address the assets with the highest risk scores before addressing the lower -risk assets. The two main components of risk are Probability of Failure (PoF) and Consequence of Failure (CoF). PoF indicates the estimated time until the asset fails to function at the established levels of service. CoF provides an indication of the impact of the asset failure considering the triple bottom line factors of sustainability: economic, social, and environmental. Every asset in the asset register is assigned a risk score. For some assets, redundancy was considered to offset the risk. The following formula is used to calculate the risk score: '� sign x aK �. e y� With each asset's risk score calculated, assets were plotted in the following risk matrix. The risk -based strategy should be to manage the high -risk zone (red zone) before moving down to medium (yellow zone) and low risk zones (green zone). HIGH Probability of Failure LOW LOW Consequence of Failure HIGH Figure 1-3 Risk Matrix Life -Cycle Cost In orderto predict the future replacement and rehabilitation need of all assets, a life -cycle cost analysis is performed. The life -cycle cost analysis is a calculation of costs required to support the set of activities (e.g., rehabilitation, replacement) that are needed to sustain the delivery of an asset's services during the life of an asset or for the planning horizon (e.g., 10, 20, or 100 years). The useful life (e.g., 10, 20, 30 years) was estimated for each asset. Life - cycle cost analysis is performed for each asset in the asset register. For every year of the planning horizon, the life - cycle analysis will calculate which asset needs a refurbishment or replacement activity and how much it will cost to perform the needed activity. As noted previously, replacement costs do not include costs associated with delivering a CIP project (e.g., engineering, project management, contingency, insurance). When all the activity costs are 5 summed for each year, the overall replacement and rehabilitation budget for the year will be established. The life - cycle cost analysis drives the estimation of the future financial needs to sustain the delivery of the assets. Comparing and contrasting the life -cycle cost results against the current asset replacement and rehabilitation spending, sustainability of the future financial plan can be assessed. Life -cycle cost calculation takes place in the form of a life cycle cost logic or management strategy. A management strategy characterizes the life -cycle behavior of an asset (e.g., how it will decay, how long it will last, necessary refurbishment during the life of the asset, when refurbishment is needed, how much refurbishment will cost). Every asset is assigned a management strategy. The following figure illustrates the relationship between asset condition, management activities, and life -cycle cost. After the installation, asset condition will deteriorate with time. In order to raise the condition to an acceptable level, an investment in the form of maintenance or rehabilitation will be required. At the end of its useful life, the asset will need to be replaced, and the cycle will repeat. 4 5 -Failed Liie Cycle Maintenarce Maintcna,re Mairmrcrm instelmt�m � ` ReUlzcemad Figure 1-4 Life Cycle Cost Logic Illustration M The life -cycle cost assessment allows the City to proactively manage the assets. The City will be able to predict which assets are nearing the end of useful life and proactively plan for replacement of high -risk assets to prevent failure. Reacting to a high -risk asset failure after they have occurred typically results in the highest expense. With life -cycle cost analysis, the City will also have an understanding of the work and investment required for future years and proactively plan ahead to minimize risk and costs. These estimations will be used to prepare the budget and resources required to sustain the delivery of services. When budget and resource limitations exist, the City will be able to prioritize the needs by risk to ensure the budget is first spent on high -risk assets. In essence, the City will be able to ensure that minimum funds are spent to maximize risk reduction. IRIS (Infrastructure Reinvestment Intelligence System) Life -cycle cost calculation can be very tedious and time consuming. It is especially difficult when the calculations need to be performed for thousands of assets, year -by -year, asset -by -asset. For this reason, the City utilized Kayuga Solution's asset management planning tool, IRIS (Infrastructure Reinvestment Intelligence System), which incorporates the developed asset register and performs the life cycle cost and risk assessment work. IRIS is an asset management dashboard that utilizes the asset data and performs asset management calculations and analyses presented in the City's asset management plan. It is a planning tool the City can use to project the 6 future maintenance, rehabilitation, and replacement needs, understand its high -risk assets, understand the cost of ownership, calculate the appropriate budget required to mitigate the high -risk assets, and identify assets estimated to require rehabilitation or replacement year -by -year, asset -by -asset. The figure below illustrates a sample view of the IRIS dashboard. JQJWr W FM Y srr. alLa1— M vu en o..

Life cycle cost analyses were performed for a 100-year, 20-year, and 10-year horizon to evaluate the replacement and rehabilitation needs of the assets. A 100-year planning horizon provides a comprehensive view of asset replacement; by the 100' year, each asset (e.g., main, valve, pump) will be replaced at least once within the 100-year planning horizon. Every year, those assets requiring replacement or rehabilitation are identified and summed to generate the replacement profile. KAYUCASCI[_U r IC3N 7 2 What Does the City Own? As part of the asset management plan development process, a comprehensive asset inventory was performed. All facilities (e.g., pump station, storage tanks, wells) were visited and their assets inventoried. Hydrants and system valves were visited and their location (i.e., GPS coordinate) was recorded. Where assets are not visible (i.e., mains, services, valves), a thorough analysis of as -built drawings and available GIS data was performed. Water main, valve, service, and meter data were initially provided by S1WC. Where the initial GIS data did not match the as -built drawing or on -site verification, Kayuga updated the initial GIS data to provide the City with a more comprehensive and current water distribution asset database. Asset Inventory The City owns 12,244 assets including nearly 60 miles of pipelines and just under 4,400 services. The water system also includes 3 water storage tanks, 2 wells, and a pump station. The following tables summarize the water distribution assets for the Cupertino Leased Area water system. The provided GIS data also included pipes from water main to hydrants and small sections of pipes to blow off and air release valves all identified in the table below.

In total, there are 12,224 assets in the water system. The replacement cost for each asset was estimated. The replacement cost does not represent a project cost that includes engineering, management, insurance, contingency, etc., costs. In many cases, project costs can add an extra 30% to 50% to the replacement cost. The sum of all individual asset replacement costs for the City's water distribution system is approximately $91.6 million in 2019 dollars. The assets were further distributed into categories based on the asset hierarchy. The sum of all replacement costs for mains, services, interties, valves, hydrants, meters, is approximately $79.0 million.

Condition is one of the best indicators for estimation of immediate and/or future maintenance, repair, and replacement work. During the asset inventory process, the condition of each visible asset was assessed and recorded utilizing the condition assessment scale introduced in Table 1-2. It should be noted that main objective of the condition assessment process is to highlight assets in poor and failed condition (i.e., Poor, Failed/Critical). These poor -condition assets will be included in the 20-year CIP recommendations (Chapter 7). Where assets are not visible, age was used as the main indicator of the condition of the asset. When installation information was not available, assumptions were made based on neighboring assets or nearby developments (e.g., construction year of neighboring houses). There is a possibility that the mains were installed long before parcel development; however, the actual installation year was unknown. In some cases, the historical record of water main break data was utilized. Where the work report indicated the cause of the main break was due to corrosion, aging pipe, or poor condition, the condition score of the pipe segment where the water break occurred was updated to reflect the poor condition. 111.1 System Level Condition Profile High-level condition profiles are provided below. These high-level profiles will be followed by specific asset analysis in the followine sections. Water System (Total) Figure 4-1 provides an overview of the estimated current condition of the water system. This condition profile includes all assets. It is estimated that about 6% of all assets fall under Poor to Failed/Critical condition. The sum of replacement cost of these assets equates to about $12.6 million. Water System (Water Mains, Water Services, Meters, Hydrants, Interties, and Others) The estimated current condition profile for water mains, water services, valves, hydrants, meters, interties, and others assets are shown in Figure 4-2. Approximately 6% of the assets are identified in poor and failed/critical condition. The total replacement cost of these assets is about $8.8 million.

The condition profiles are either represented as current percentage of Poor and/or Failed/Critical assets or as replacement needs for the next 10 years. Water Mains The following installation profile shows the decade the water mains were installed or last replaced. When installation information was not available, assumptions were made based on neighboring assets or nearby developments (e.g., construction year of neighboring houses). The oldest water mains were estimated to have been installed in the 1950s and 1960s. The following figure presents the age by decade of the water mains with respect to total length. It is estimated that about 38% of the water mains are now over 50 years old. It should be noted that older pipes may potentially exist in the City. According the City's Lease Water System Inspection Technical Report', the City has a logbook that dates the water mains back to 1916. It stated that the City's water system was originally constructed in 1916 and then expanded in 1938 and 1950s. Unfortunately, no historical as -built drawings could be found to verify this claim. The oldest pipe in the GIS data showed to be constructed in the 1950s. i1970s, 2991 198Us la% 1990s 11% 1 1960s.2010S J0% 1 195& i - 9% Figure 4-4 Water Main Installation by Decade ' SPF Water Engineering, "Final Technical Report: Leased Water System Inspection," 2017.

Figure 4-5 Water Main Installation History by Decade Estimates of pipe useful life play a key role in the asset management analysis for underground pipelines. According to a comprehensive study conducted by Utah State University2 on water main break rates in the USA, the average age of failing water mains is approximately 50 years old. This number is well below what is usually recommended by most of the pipe manufacturers. The study also found that the break rate of asbestos cement (AC) pipe significantly increased by 43% after reaching 50 years of age. The study concluded that AC pipe installed in the 1960's may be near its end of life. In addition, the study indicated that an average expected life of a newly installed pipe is 84 years. Typical new installation pipe materials included ductile iron (DI), PVC, HDPE, concrete steel cylinder (CSC), polyvinyl chloride (PVCO), and steel. A similar study conducted by the US EPA stated that post World War II cast iron (CI) pipe average service life is about 75 years. The US EPA study provided the following expected service lives for different pipe materials: • AC pipe 15 inch or greater — 85 years • AC pipe 4 inch or smaller— 40 years • DI pipe — 87 years • Reinforced concrete pipe —140 years • Concrete —130 years • CI pipe — 75 years z Folkman, Steven. "Water Main Break Rates in the USA and Canada: A Comprehensive Study." Utah State University Buried Structures Laboratory (2018). 3 "Primer on Condition Curves for Water Mains." US Environmental Protection Agency. EPA/600/R-13/080 (2013). KAYUG^'CO) UiIC)N . 17 In addition, a recent study by the Sustainable Solutions4 stated that the following useful lives • PVC pipe -100 years • DI — 50 years • HDPE-50years Multiple water main useful life scenarios were developed and modeled to gain understanding of anticipated water main replacement needs for the next 10 years. Careful analysis of the scenario results can yield a better understanding of future water main replacements. Scenario 1— US EPA Useful Lives A simulation of expected water main replacements was performed utilizing the US EPA pipe useful life presented above. For those pipe materials not identified by US EPA, a useful life of 84 years was used. This number is based on the Utah State University research presented above. Based on this analysis, it is expected that 10-year water main replacement will be about $1.4 million or about 3% of the total water mains. This value represents the pipes currently identified in the leak data to be in poor condition. Scenario 2 — Conservative (100-Year Useful Life) This scenario provides a conservative look at the water main pipe replacement needs. All pipes were assigned a 100- year useful life. From the water main data, the earliest water main installation recorded in the City was 1954. With a 100-year analysis, the earliest water main replacement will in the mid-2050's, out of the 10-year water main replacement window. Similar to Scenario 1, the 10-year water main replacement is expected to be about $1.4 million (3%) for the replacement of identified poor condition pipes. Scenario 3 — Aggressive (65-Year Useful Life) This scenario is developed to represent the worst -case scenario. All pipes were assigned a useful life of 65 years. In reviewing the water leak work data, the representative age of all pipes identified as structurally in poor condition was about 65 years. Based on this analysis, it is expected that the city has to replace about 17% of the total water mains worth $7 million. Scenario 4 — Hybrid (65-Year Useful Life for AC Pipes and US EPA Useful Lives for Other Pipe Materials) This hybrid scenario was designed to provide a more representative view of the City's water main replacement needs. As indicated in Scenario 3, the representative age of water mains identified to be poor condition was 65 years. Closer review of poor condition water mains revealed that they are mostly asbestos cement (AC) pipes. In this scenario, all AC pipes were assigned a 65-year useful life while other pipe materials were assigned useful life identified by the US EPA. This assumption is supported by the Utah State University study5. The study revealed that, for AC pipes, the frequency of leaks increased by 43% after 50 years. In another words, after the 50th year, the AC pipe decay curve (Figure 1-2) rapidly falls, indicating that there is little service life left before failure. A majority of AC pipes in the City were installed in the 1950's, 1960's, and 1970's. Based on this analysis, it is projected that the City will need to spend " "Life Cycle Assessment of PVC Water and Sewer Pipe and Comparative Sustainability Analysis of Pipe Materials."

Scenario 5 — San Jose Water Company Useful Life This scenario uses water main useful lives recommended by SJWC. According to SJWC, life expectancy is 85 years for AC, 110 years for Cl and 70 to 85 years for WS mains. The remaining mains are estimated conservatively to have a 100-year useful life. Based on this analysis, it is expected that the City has to replace about 4% of the total water mains worth $2.9 million within the next 10 years. Water Main Useful Life Scenario Summary The summary of scenario results is provided in table below. Although it is difficult to predict exactly when the water mains will fail and how much budget is required to replace them, the scenarios provide an expectation between the worst -case and the best -case scenarios. The conservative and aggressive scenarios establish the two extreme numbers. From there, both the hybrid and SJWC numbers incorporate system knowledge in the analysis. From the scenarios, the City may expect to spend about $3 to $6.6 million for water main replacement in the next 10 years.

The following figure shows the installation profile of the water valves by decade. Like with the mains, assumptions were made based on neighboring assets when installation information was not available. Similar to water mains, 31% of valves are over 50 years old. KAYUGA`i Cll_ CIiICIN 19 Figure 4-6 Valve Installation Profile by Decade The figure below presents the condition profile for water system valves (i.e., air release, air vent, blow off, line, zone). It was assumed that the water system line valves would be replaced when the main is replaced. As such, the installation year and useful life were set to be the same as the nearest main. Valves on AC pipes were set to 65 years and valves on other pipe materials were set to US EPA recommended years. Data analysis show that about 10% of the valves are in Poor and Failed/Critical condition. In the next 10 years, it is anticipated that the City will need to spend about $160,000 to replace aging valves.

Like the water mains and valves, some of the oldest hydrants were installed in the 1950s and 1960s. Currently, about 11% of hydrants are expected to be 50 years or older. Kl yU G/N �C.11 t11 I[Jfl 20 Figure 4-8 Hydrant Installation Profile by Decade The figure below presents the condition profile of the hydrants. Useful lives of hydrants have been stated to be anywhere between 40 years to 100 years. A 100-year useful life was used in this analysis as the previous condition assessment work (Technical Report of the Leased Water System Inspection, 2017) revealed the hydrants to be in good condition. In general, hydrants are visible and regularly tested and exercised; as such, hydrant condition tends to be more updated and managed compared to other buried assets. Cities and water providers near Cupertino (e.g., City of Livermore, Santa Clara Valley Water District) also utilized a 100-year life for hydrants. The following condition profile reveals the hydrants to be in good condition or better. Figure 4-9 Hydrant Condition Profile In the next 10 years, fire hydrant needs were limited to maintenance activities (i.e., testing and paint). During our field visit, numerous fire hydrants that are in need of repaint were identified. It was assumed that a typical per unit cost to sand blast, prime, and paint a fire hydrant is $125. At this rate, the total need for next 10 years was $44,500. No fire hydrant replacement needs were identified. Water Services The following figure presents the installation profile of the water services by decade. Like the mains, there were many services for which the installation year was not available. As such, age assumptions were made based on neighboring assets or nearby developments (i.e., construction year of neighboring homes). Based on these assumptions, approximately 28% of services are estimated to be 50 years old or older. 21 - ��`�' ,�;.�'�-.�ny,?"��F'n �. �".s i�>i� ��a. £,� + �'� � * � q?a`�^•'�'.'t,� ;;tax*'�r "�.. ; ' ��'"ca ���:-� 3� �,` �, •:a ,; ++# a �k'�:�au t � `F �'_ 4'` `-�_�?„�'c� t, t``�r E :z�,,;' 18% OOOSj 8"� 6% _ 2olos� 1980s1 13% 1950s 119707s'l F 05 L21% Figure 4-10 Water Service Installation Profile by Decade Due to a thinner pipe wall, water services typically have shorter service life when compared to water mains. Multiple analyses were performed using varying water service life (i.e., 50-years, 65-years, 80-years) to gain understanding of the expected condition and their resulting budget for replacement. These scenarios were developed based available data analytics and from similar projects from nearby areas (e.g., Livermore). It is important to note that, due to lack of available data, the installation year of water services were estimated to be equal to neighboring assets (i.e., water main) or nearby developments (e.g., construction year of neighboring homes). It should also be noted that, as mentioned in the water main analysis section, that some water mains could be older than shown in the database. According to water service installation data from the past 20 years, over 450 services were replaced since 1997. This equates to about 10% of water services in the City. Further examination of the data revealed that the 53% of the replaced water services were connected to AC water mains where the average age was 43 years old. If water services were installed at the time of water main construction, it can be deduced that useful life of water services is about 43 years. However, since the City is not experiencing daily water service breaks, the scenario analyses of the water service useful life were represented as 50-years, 65-years, and 80-years. Scenario 1-50-Year Water Service Life An expected useful life of 50 years was used to model the condition of water services. Using a 50-year useful life, it is estimated that about 44% of water services are in Poor to Failed/Critical condition. The total replacement cost of these water services equates to approximately $10.3 million. The Failed/Critical condition water services alone summed to approximately $6.9 million. Failed/Critical condition water services are estimated to have exceeded their expected lives.

In this analysis, it is assumed that water services will be replaced at the same time water mains are replaced. In the water main discussion above, it was concluded that reasonable expected useful life of an AC pipe is 65 years. As approximately 60% of the City's water mains are AC (Table 2-2), water service useful life was set to 65 years to assume that water services will be replaced at the same time. The following figure shows the water service condition profile based on 65-year life. In this scenario, services in Poor or Failed/Critical condition equated to 12% or approximately $2.7 million dollars. _.

With the earliest water service installation taking place in the 1950's, an 80-year useful life scenario will push any replacement need for the water services out of the 10-year planning window. As expected, no water services were identified to be in Poor or Failed/Critical condition. i<wUC;A'-,t, L,r—;J 23 0 E..Iha 39% Very G—d. 5DA Gaod: 11% Poor. 0% iailediC,4-1: 0% Figure 4-13 Water Service Condition Profile at 80-Year Useful Life Water Service Useful Life Scenario Summary The following table summarizes the water service scenarios. Water service data revealed the average life of the services that have been replaced was 43 years. In addition, the data showed that many services that were replaced were connected to AC pipes, the oldest pipes in the City. As water service pipe walls are thinner, it will be tough for water services to match the life of the water mains. Given this fact, if a reasonable useful life approximation of an AC pipe is 65 years, it will be realistic to assume that water service replacements may reach about $3 million within the next 10 years.

For those assets not visible or accessible, the condition of the asset was estimated based on age. Mann Pump Station The following figure provides an overall asset condition profile for the Mann Pump Station. It was noted during inspections that the pump station is aging; original construction is estimated to have taken place in the 1980's. As shown in the figure, many assets have been replaced since original installation and were in good condition. About 18% of the assets, however, were noted to be in Poor or Failed/Critical condition. In particular, the emergency generators and electrical controls were noted to have likely exceeded their useful lives, and the ability of the generators to provide power when needed was questionable. In addition, pump number 3 is aging and is in need of replacement. The estimated total replacement cost of these assets is about $1.1 million.

As shown in the figures, the Cristo Rey Storage Tank is in very good condition as it was constructed in 2000. Mercedes Station Tank #2 was recently rehabilitated in 2018. Mercedes Station Tank #1 is currently out of service as the current water demand - I<AYUGASt ;I l� I IUf�-i 26 does not require it. However, if the water demand increases, Tank #1 will be required again. A full rehabilitation will be required if Tank #1 is to come back on line. In 2018, Tank #2 was rehabilitated for $1.5 million.

PoF was represented by a score of 0 (new or very low probability of failure) to 1 (failed or very high probability of failure). An asset failure is represented by different failure modes (i.e., mortality, capacity, level of service, financial efficiency). For the mortality failure mode, asset condition score or age was the key factor in determination of the PoF score. For water mains, historical main breaks were also incorporated. For the capacity failure mode, hydraulic modeling work was performed to identify any capacity issues in the water system. The results of the hydraulic modeling indicate that the current system is capable of meeting current and future demand. However, field sample testing was lower than the hydraulic modeling capacity. The field results could be due to valve issues, leakage, or other issues; more investigation is required. For more information on the hydraulic modeling, refer to Appendix B. For the level of service failure mode, the need for changes to the system to support the service demand were incorporated in the asset failure. These included water pressure, water quality, regulatory, safety, and emergency concerns. For the efficiency failure mode, low efficiency (e.g., financial, energy) was the key factor for identifying asset failure. 5.2 Consequence of Failure The CoF is a numerical measurement of the criticality of the asset, that is, the impact of the asset failure. Where applicable, the impact of failure was assessed with respect to the triple bottom line factors of sustainability: economic, social, and environmental. CoF scores were assigned on a scale of 1 (low criticality) to 5 (high criticality). The CoF is used to help prioritize the asset under limited budget and resources. Prior to the asset management project, S1WC conducted a CoF analysis as documented in the 2015 Pipeline Consequence of Failure Study (Appendix C). The goal of the study was to rank each segment of the water pipeline from the highest to lowest consequence of failure. The following consequences were considered during the CoF evaluation • Health and Safety o Potential water quality hazards due to contamination infiltration o Potential for injury due to flooding o Disruption to critical facility operations • Transportation o Disruption to traffic along high traffic volume roads • Business o Disruption to businesses • Systems Operations 29 o Water supply shortage due to transmission main damage o Water system facility disruption due to critical pipeline damage Based on the principles of asset management, the CoF methodology was concluded to be sound. The CoF scores for the water mains were incorporated into the asset management study. In some cases, the water main IDs had changed since the 2015 study. These changes are likely due to water main replacement. Where possible, the score from the study was applied to the new pipe ID; where the new and old pipe IDs could not be reconciled, the score from the neighboring pipe was applied. In order to make the main CoF scores consistent with facility asset CoF scores, the scores and ranking from the 2015 study were normalized to the 1 to 5 scale as summarized in the following table. Table 5-1 Water Main CoF Scoring 107 to 212 10% 22% 4 213 to 530 32% 33% 3 531 to 760 22% — 27% 2 761-1061 27% 26% 1 The following figure illustrates the CoF scores for the water mains. Valves along the water mains (e.g., line valves, blow off valves, air release valves) were given the same CoF score as the highest-CoF main to which it is attached. "eel .

As hydrants provide critical emergency services, they were given a CoF score of 5. Water meters and services were given scores based on size. The greater the disruption a water service failure would cause, the greater the economic consequence of a failure.

Facility assets were given CoF scores based on their importance to the overall facility's ability to function. As such, many of the major mechanical and electrical assets (e.g., pumps, motors, emergency generator, MCC) were given high CoF scores.

This profile incorporates both the Probability of Failure (PoF) and Consequence of Failure (CoF) scores to prioritize the assets. The assets in the red zone of the risk matrix are the highest risk assets. Under limited resources, assets in the red zone should take priority over others in terms of being replaced. There are 26 high -risk assets with a total estimated replacement or rehabilitation cost of approximately $3.8 million. These assets are composed of water mains, water distribution system valves, water services, emergency generators, and tank rehabilitation at Mercedes Road. It should be noted that, as mentioned in Section 4.3, that Mercedes Station Tank #1 is currently not operating as the current water demand does not require it. However, if the water demand returns to historical level (3 MGD), Tank #1 will need to be operating again. More discussion on the need of Tank #1 will be provided in the CIP section (Chapter 7) of this report. The high -risk assets will be included in the 20- year CIP recommendations. The 148 assets in the medium risk (yellow zone) include water mains, water services, fire hydrants, and others. Under ideal conditions, all assets would be replaced as they reach PoF 1 at the top of the matrix; the replacement should be prioritized based on risk (red, yellow, and green).

Levels of service are performance indicators expressed as specific, measurable outcomes with defined time constraints. Service levels support priorities expressed in strategic plans, budget objectives, and policy -maker direction. The City should use levels of service to describe a commitment to service delivery, sustainability and risk management, asset performance, and regulatory compliance. Service levels are measured on a regular basis to learn where the organization is meeting or exceeding its goals and where improvement is needed. Service levels also indicate the level of effort and likely costs the agency must incur to meet its goals. The International Organization for Standardization in its Asset Management Guidelines (ISO 55002:2014(E)) note that defining service levels help ensure that the organization's assets are meeting the needs of customers and other stakeholders. In order to develop levels of service for the City's water distribution system, four categories of indicators should be considered: 1. Sustainability - Sustainability topics will include minimizing the environmental impact of water operations, providing adequate financial resources for operations and capital needs, and maintaining a data -driven, effective organization. 2. Asset Performance - The asset performance section will identify actions required to obtain maximum performance and value from the community's investment in infrastructure. 3. Customer Service -The customer service category will address rate payers' expectations for product quality and reliability and for responsive, effective assistance from water organization employees. 4. Regulatory Compliance - Regulatory compliance will call out the responsibilities of the water agency to remain in compliance with the elements of the California Water Resources Control Board (WRCB) permit, state laws, and water regulations. The tables below contain 51 level of service measurements recommended for the City. The indicator's level of importance is ranked on the following scale. Table 6-1 Level of Service Importance Ranking Rank Description 3 Critical 2 Important 1 Useful The measurements that matched AWWA "Benchmarking Performance Indicators for Water and Wastewater (2016 Edition)" are accompanied by the AWWA's benchmark numbers represented as high, median, and low percentiles of performance. Management and policy -makers often use these indicators to monitor performance and track the movement in the set direction. 6.1 Environmental, Organizational, and Financial Sustainability Levels of Service The following table presents the recommended sustainability level of service to ensure stability by minimizing impact on the environment, maintaining an effective, productive organization, and ensuring that current and future financial obligations will be met.

The ability of underground and above ground assets to function properly facilitates delivery of potable water to customers. Establishing asset performance measurements will give management and policy -makers the guideposts needed to keep the organization's physical assets functioning at desired levels. A complete asset inventory, including criticality, will be instrumental in planning and executing preventive and corrective maintenance. Identification of critical assets and careful assessment of risk, updated routinely, will assure that limited resources are directed toward assets with the highest impact and probability of failure.

The next step in the asset management analysis is to investigate the current and future asset replacement and rehabilitation needs. The future needs of the water system were evaluated based on the following methods: • Condition and Age • Level of Service • Efficiency The condition and age -based analysis focuses on the physical mortality of the assets, including when the assets need replacement and how much it will cost. The level of service analysis investigates the current system's ability to continue delivery of services, including capacity and safety. The efficiency analysis evaluates the system for any efficiency recommendations. 7.1. Condition and Age Based Analysis In order to estimate the long-term asset replacement and rehabilitation needs in terms of physical mortality, a life - cycle cost analysis was performed for each asset. As described in Section 1.2 of this report, each asset class was assigned a life cycle cost logic or management strategy (e.g., useful life, decay curve, rehabilitation activities) that includes the rehabilitation and replacement activities to best characterize the life cycle investment needs for the asset. The estimated useful life is based on industry standards/reference documents (e.g., AWWA, Water Research Foundation, US EPA, Utah State University) or similar projects nearby the City (e.g., City of Livermore, Santa Clara Valley Water District). Assets in condition 4 or 5 that fail within the planning horizon are included in the long-term replacement needs. The following table summarizes the management strategies.

Three planning horizons were utilized: 100 years, 20 years, and 10 years. A 100-year analysis provides a visualization of full replacement of all assets in the water distribution system (e.g., water main with 100-year life). For planning, a 20-year view provides a closer outlook of any upcoming spikes. A 10-year horizon will provide a more detailed information on what assets are anticipated to fail in the near future. 100-Year R&R Analysis The result of a 100-year life cycle analysis is provided below. The total asset replacement and rehabilitation needs for the next 100 years is estimated to be $164.9 million. The average annual asset replacement and rehabilitation need is approximately $1.6 million in 2019 dollars. Inflated costs were not calculated as the long, 100-year, horizon exponentially increases the total replacement and rehabilitation sum. In addition, the City will never plan based on a 100-year planning horizon. In the first couple of years, most replacement and rehabilitation needs are for water mains, valves, services, and meters; the overdue replacements include water services that are estimated to need replacement and recommended replacements at the facilities (e.g., emergency generators).

Water Mains The following figure presents the projected water main replacement for the next 20 years. As discussed previously, a large portion of the water mains are aging and are estimated to need replacement in the near future. In particular, AC mains estimated to have been installed in the 1950's and 1960's will are estimated to need replacement. In the next 20 years, approximately $17.4 million worth of mains are estimated to need replacement, with an annual average need of approximately $869,000. sz000.000 $1,000.000 So 2020 2025 2030 2035 Year Figure 7-6 20-Year Replacement Profile for Water Mains An additional analysis was conducted on the future main replacement needs using a probabilistic method.

Table 7-4 20-Year Water Services and Water Meter R&R Summary 20-Year 20-Year, Probabilistic Backlog Analysis $14.1 million $704,000 $7.4 million $371,000 Analysis was performed to compare and contrast the projected asset replacement and rehabilitation work since the start of SJWC's operation in 1997 to actual work performed by SJWC. A life -cycle cost analysis was performed with start year of analysis set to 1997. A planning horizon of 21 years was used to project the asset replacement and rehabilitation needs from 1997 to 2018. According to the analysis, an estimated asset replacement and rehabilitation needs for the 21-year period was $10.3 million. From this value, assets identified with known install year between 1997 and 2018 were removed. This assumes that those assets were installed under SJWC's management. The sum of all assets installed between 1997 to 2018 equated to $8.8 million. Taking $8.8 million from the projected $10.3 million reveals a value of $1.5 million. In theory, $1.5 million should be the amount of backlog not addressed from 1997 to 2018. However, the confidence level of $1.5 million is low. According to the City, SJWC reported having spent $5.73 million on asset rehabilitation and replacements since 1997. Based on this fact, the actual backlog of work could range from $1.5 million to $4.57 million. KAY U G A S nI_ U T I C-3N 47 7.2 Level of Service Analysis The Level of Service analysis investigates the need for changes to the system to support the service demand. A capacity analysis considering both the current and future demand for water services in the water system was performed as part of the asset management study. The demand includes fire flow demands. As identified in the Cupertino Leased Water System Capacity Analysis (2018), no excessive capacity issues were identified under current demand. The future demand analysis shows that the system demand trend has been decreasing in recent years due to the state-wide drought. In addition, limited or no growth is expected in the service area. As such, the system has the capacity to support future water demand. For more information about the water demand and capacity analysis, refer to the Cupertino Leased Water System Capacity Analysis (2018). If the water demand rises, it is recommended that the City bring the Mercedes Road Storage Tank #1 back in service. Figure 7-10 shows a 10-year history of average water consumption. Since 2008, the average water consumption in Cupertino has steadily declined due to drought and water conservation programs. However, after recent wet winters, the graph reveals the average water consumption rising again. In 2008, the average water consumption was 3 MGD. In 2017, this value dropped to 2 MGD. At 2 MGD, the total capacity required is 3.3 MGD, using a design factor (maximum daily demand) of 1.5 and fire flow requirement of 0.3 MGD. Even with Mercedes Road Storage Tank #1 out of service, there is enough storage (4 MG) in the system to handle this load. However, as the graph shows, starting 2018 there is a bit of upward trend in water consumption. If this trend continues, when the average water consumption reaches 2.5 MGD, the total required storage capacity will reach over 4 MG. In 2018, the average water consumption was 2.26 MGD. The estimated cost to bring Mercedes Road Storage back in operation is approximately $1.92 million. This estimate includes rehabilitation, seismic upgrades, adding mixers, and other safety upgrades. This cost is reflected in Table 7-9. Average Water Consumption 3.5 3 2.5 2 1.5 1 0.5 0 ___..... _._..___.__.._._..,._....._ _._.._..

Another recommended project is related to the chronic low service pressure at Inspiration Heights. During the project and capacity investigation, it was found that 22 service locations have low pressure concerns. A closed water I<AYUGA �<� Iil l'll.l 48 service pressure zone should be investigated as a solution. This project includes the assessment and design, as well as the installation of a hydropneumatic tank, a small 24-hour pumping system and standby fire pumps, and a separate distribution piping system for an estimated $500,000. This project is recommended to be implemented within 5 years. The connection/development of a SCADA monitoring system for the City is another recommended project. The priority of this recommendation varies based on whether the City chooses to operate the system or not. Even if the City does not operate the system, it will be helpful for the City to have the ability to monitor the status of the Leased Water System. This project is estimated to cost $300,000. This project is recommended to be implemented within 10 years, or earlier if the City decides to operate the system. In addition, level of service includes the investigation of upgrades for regulatory, safety, and emergency concerns at the facilities. Seismic and emergency power upgrades for the storage tanks and wells were identified. The following table shows the recommended level of service upgrades for the facilities.

In the Recommended Levels of Service, reduce electrical power costs year over year and increase alternative energy sources and fuels was one of the recommendations. The following projects will also help to address this level of service.

Introduction and Purpose The Cupertino Leased Water System Capacity Analysis was performed to support the Asset Management and Valuation investigation for the City of Cupertino. Cupertino owns a public water supply and distribution system, the operation and maintenance of which has been leased to the San Jose Water Company (SJWC) since 1997. The lease is for 25 years, and will end in 2022. The San Jose Water Company Service area and Cupertino's leased water system service area are shown in Exhibit 1. The City is performing its due diligence to determine system integrity and capacity. As part of the City's due diligence investigation, it contracted with consultants in recent years to begin the process of affirming the water system operation and maintenance activities meet the lease agreement requirements, and that operation of the system is in accordance with customary utility practice and within the Operator's standards of the other water systems it owns and operates. The capacity analysis is a recommendation in the Final Technical Report Leased Water System Inspection, by SPF Water Engineering (January 12, 2017). K AYUCA r 1 2 Leased Water System The City of Cupertino's leased system serves the northwest third of its City boundary, as shown in Exhibit 2. The City has leased out its operation and maintenance to San Jose Water Company, which owns a separate water system serving the southern portion of the City. California Water Service Company serves the remainder of the City in the northeastern area of the city. The water system operates in a supply zone and two separate distribution pressure zones, and consists of City - owned groundwater well supply and imported water supply from the Santa Clara Valley Water District (SCVWD). SCVWD is a wholesaler for retail water utilities including SJWC and the City of Cupertino. The system serves 3.7 square miles of the City and consists of approximately 60 miles of water pipelines (ranging in diameter from 2-inch to 20-inch); 4,554 customer service connections (as of 2017); three 2.0 million -gallon (MG) reservoirs at two reservoir sites (Mercedes and Cristo Rey); a forebay, five parallel booster pumps and imported water supply source at the Mann Drive Pump Station site with total rated capacity of approximately 6,000 gpm capacity; two off -site wells and Homestead Road/Stelling Road transmission system; and two regional pressure -reducing stations at the Mann Drive Pump Station site. These facilities serve, on average, 800 to 1,000 million gallons per year, and represent about two percent of the total water served by San Jose Water Company. 2.1 Service Area and Applied Loading The leased system service area is virtually built -out and consists predominantly of residential land uses. The City's Community Vision 2040 general plan defines the following Special Areas and residential communities within the water service area of the leased system: — Bubb Road (low-rise industrial and research) — Monte Vista Village (residential, neighborhood commercial, public and industrial) — Oak Valley Neighborhood (residential) — Creston-Pharlap Neighborhood (residential, includes school) — Inspiration Heights (residential, includes institution and Mercedes reservoirs) — Monte Vista North (residential, schools) — Garden Gate (residential) According to the general plan, limited or no growth is expected from these areas except for 42 acres of vacant privately -held land that could develop homes on a portion. This would still represent minimal increased demands in the future and not be significant for the model analysis. KAYUGA' CJI 1111:.Ji t %..2 System Demands The Annual Reports SJWC produces for the Cupertino Municipal Water System identifies average annual demands of the leased water system as follows: Table 2-1 — Average Annual Water Demands Year (million gallons per day) Land Use 2013 2014 2015 2016 2011 1.04 Commercial.0:0 0.77 0. 0.00 t 1112 Total MGD 2.99 2.80 1.98 1.91 2.04 Total gpm 2,077 1,945 1,377 1,324 1,419 The trend seen here with lower demands in recent years is typical of what the industry has observed due to the persistent state-wide drought. Since 2011, California has been in one of the most severe extended droughts on record. Peaking of demands is an important consideration in water model simulations for two reasons — fire flow analysis and peak demand analysis. Peaking information for the leased system was requested but not provided for the modeling investigation. First, fire flow simulation is standardized by the California Fire Code (CFC) and required to be analyzed during maximum -day normal demands. 'Maximum -day' represents the largest volume of water demanded by a water system over a 24-hour period. Typical for public municipal water systems, the maximum daily volume occurs in the summer time when irrigation demands are at their highest. Second, peak normal demands for public water systems occur for much shorter periods. For public municipal water systems, these peaks, commonly referred to as "peak - hour", occur during the early morning and early evening hours just before the work day begins and just after the work day ends, as people shower in the morning and use dishwashers and clothes washers in the evening. Depending on the size of the public water system and land use make-up, maximum -day demand factors could range from 1.5 to 3.0 times average demand flow; and peak -hour factors could range from 2.5 to 5.0 times average demand flow. Considering the size of Cupertino's leased system, with a usage that can exceed 2.0 million gallons per day on average, the modeling study adopted 2.0 for the maximum -day factor and 4.0 for the peak -hour factor. 23 General System Operation A current water master plan outlining system operation, including water supply and distribution characteristics, was not available for this study. The general operation was gleaned from provided documents, a phone interview, and e-mail correspondence with San Jose Water Company staff. The leased water system is supplied by imported water from the Santa Clara Valley Water District and groundwater from City -owned wells outside of the leased system service area. The Franco and Flowering Pear Wells are located within the City of Cupertino but outside the leased system service area adjacent to Homestead Road and Forge Way.

The imported water supply is from a Santa Clara Valley Water District connection and meter at the Mann Drive Pump Station (MDPS) site. Both supply sources are designed to fill the Mann Drive Pump Station 400,000-gallon forebay. The forebay acts to supply stable suction hydraulics for the MDPS pumps. The leased water system operates in an "open" system with reservoirs at elevation to supply system pressure by gravity. MDPS pumps operate to maintain water levels in the reservoirs at approximate pad elevation of 600 feet, namely the Mercedes and Cristo Rey tanks, which have a total capacity of 6.0 million gallons (MG). Considering the total demands of the leased system and fire flow volume requirements, the leased system storage capacity should be adequate for "time -of -use" operation. Time -of -use refers to avoiding the need to operate system facilities like pumps and wells during peak electrical power costs. Pumping only during off-peak hours is the preferred operation of water utilities in order to minimize operating costs. However, SJWC staff indicated that in order to maintain water service pressures at the highest elevations of the system, the reservoir levels must be maintained at or near high water level at all times (approximately 630 feet elevation). Staff indicated that the pumps must turn on every two- to four- hours in order to maintain the water levels, depending on the time of year. This requires short and frequent pumping periods that could also significantly reduce pump life. SJWC staff also indicated that the primary source of supply is from Santa Clara Valley Water District imported water. Typically, local groundwater production that is not brackish (very low quality requiring reverse osmosis treatment) is more cost effective than paying for imported water. The City should investigate the cost of the two sources, considering water quality, conveyance, well improvements and pumping rights, and control of its own water supply. The lowest elevations at the northeast end of the service area are pressure -reduced to manageable pressures because static pressures at elevations below about 280 feet (elevation above mean sea level) are excessive and could be dangerous for maintenance and upkeep. Lowering pressures is also a very effective way of reducing water loss. The "Mann Regulated Zone" consists of approximately 250 residential connections. Hydraulic Model and Field Testing The computer water model provided by SJWC staff was pre -loaded with 'average' demands totaling 1,682 gallons per minute (gpm), which is consistent with system demands from the Annual Reports. Another component of water demand and sizing of distribution facilities is fire flow. Standardized fire flows for different types of land uses are typically provided in Water Master Plans or other hydraulic analysis reports that were not available for this modeling study. Current fire flow requirements are listed in the California Fire Code (CFC) as high as 8,000 gpm at 20 psi, with reductions allowed when fire sprinkler systems are included in building construction. Invariably, large structures are conditioned for fire sprinklers regardless of construction materials used. The CFC allows for a reduction in fire flow requirements of up to 75 percent. Also, fire flow requirements for the purposes of the model analysis should consider that many of the structures within the City's service area were likely constructed at a time when the fire flow requirements were lower. With these considerations, and the limited expected development or redevelopment that could occur, it is reasonable to evaluate the leased system capacities at various locations based on land use with the fire flow requirements as stated in the Final Technical Report, and summarized in Table 3-1: Table 3-1 — Capacity Requirements Single-family 1,500 2 180,000 Residential 1 Multi -family 2000,2 240,000 Residential All other -- zoning 2,500 2 I 300,000 I The following is a summary of system demand loadings used for the computer model analysis: Table 3-2 — System Demand Loadings Average Demand Max -Day Demand Peak -Hour Demand System -wide System -wide System -wide .� •. Note: 2*Avg = Max -day; 4.0*Avg = Peak -hour The Innovyze modeling software (formerly MWH Soft) InfoWater was used in a stand-alone version (no AutoCAD or Arcview platform) in instantaneous analysis mode. The scenarios selected were designed to analyze system capacity at different land uses throughout the service area. These scenarios were then field tested to validate system performance. Appendix A includes a graphic of the leased system water model. K AYUGA 5 The computer model includes the complete distribution system from the Mann Drive Pump Station to the Mercedes and Cristo Rey tanks. In all, nine simulation scenarios were performed for the purposes of hydraulic model analysis and establishing hydraulic bases for comparing with field flow testing: Scenario 1: Supply scenario, zero system demand, Mann Drive PS operating Scenario 2: Max -day system demand (3,364 gpm), normal operation, MDPS off Scenario 3: Peak -hour system demand (6,728 gpm), normal operation, MDPS off Scenario 4: Max -day plus FF #1(Exhibit 3), 2500 gpm at Alves Street (J23992), MDPS off Scenario 5: Max -day plus FF #2 (Exhibit 3), 2500 gpm at Mary Avenue (J23440), MDPS off Scenario 6: Max -day plus FF #3 (Exhibit 3), 2500 gpm at Scenic Circle (J44068), MDPS off Scenario 7: Max -day plus FF #4 (Exhibit 3), 2500 gpm at Alcalde Drive (J63366), MDPS off Scenario 8: Max -day plus FF #5 (Exhibit 3), 2500 gpm at Ainsworth Drive (J65056), MDPS off Scenario 9: Max -day plus FF #6 (Exhibit 3), 1500 gpm at Voss Avenue (J65056), MDPS off Simulation Scenarios 1, 2 and 3 provide hydraulic characteristics under normal conditions. Scenarios 4 through 9 simulate foreseeable emergency fire events at critical locations. InfoWater includes a fire flow tool that, for each fire flow simulation, evaluates the entire system for deficient pressures in addition to meeting the minimum 20 psi at the fire flow location. This analysis uses the minimum pressure criteria for the fire flow junction of 20 psi (based on Uniform Fire Code), and maintains positive pressure everywhere else in the system. Table 3-3 summarizes the hydraulic analysis results for the fire flow scenarios. 1 1 - 1 2 - L. 3 - J23992 J23440.

[2] As designated for the Final Technical Report (SPF Water, January, 2017) KAYUGASOLUTION 6 Other parameters important for hydraulic analysis evaluation are maximum flow velocity and minimum system pressure. Typical maximum velocities for design of public water systems are 3 to 5 feet per second (fps) for normal operation, and 10 to 17 feet per second for emergency fire flow conditions. The typical standard for minimum pressures during normal operation is 40 psi to ensure adequate pressure for second floors of residential structures. Although the velocities resulting from the analysis are within these criteria, the minimum system pressures are not. Table 3-4 is a summary of the maximum velocities and minimum pressures observed for each scenario.

SJWC addresses this in a January 4, 2017 fire flow analysis memorandum and identifies these service areas as customer services with 'less than 20 psi' or 'no water' with a boil -water -advisory should a fire event occur. Even under normal conditions, as indicated in Table 5, service pressures can be less than 10 psi during normal conditions. It is assumed these services incorporate private pumping for adequate shower pressure, as well as dishwasher and clothes washer appliance pressure. The SJWC memorandum is included in Appendix B. Scenarios 4 through 9 indicate adequate fire flow capacity for all locations except Garden Gates and Inspiration Heights. Scenarios 4 through 8 were field tested on November 20, 2018 by J&C Fire Protection. Field flow testing was recommended as a result of the findings of a series of technical memorandums of the Final Technical Report study (SPF, 2017). The flow testing crew, supported by SJWC and City of Cupertino staff, locate the desired hydrant to flow and a separate location for reading system pressures (normal operating pressure prior to flowing the hydrant, often called 'static'; and dynamic pressure during flow typically referred to as 'residual') and performed the proper flow testing procedure at each site. These field measurements should be taken periodically to confirm model results. The results of the field flow tests performed are included in Appendix C. Table 3-5 includes a comparison of the fire flow analysis between model results and field flow testing results, and shows a distinct difference in all but the Alves Street location.

Estimated elevation of flow test at Alves Street is 270 feet, 630 HWL - 270 = 360 ft = 156 psi. Assuming the geometry of the model provided by SJWC was confirmed for accuracy — i.e. elevations, pipe lengths, and pipe diameters — this could be an indication that pipe connections thought to have been constructed were actually not constructed (adversely affecting circulation and system capacity), or pipe roughness factors should be much lower in the model, or both. In addition, old or broken valves not properly abandoned, or thought to be removed, could also reduce system capacity. In any event, these major differences in field and modeling data should be corrected to acceptable tolerances before relying on modeling data for any further system analysis. 9 The apparent deficient fire flow at Alves Street could be a settings error in the model that needs further investigation. Review of the results reports indicate twice the flow as necessary flowing through the Mann regulation valves causing erroneously high headloss readings. Reducing the headloss will result in higher available flow to Alves Street and the entire Mann Regulated Zone service area. Z1 Capital Improvements Evaluation of the water system capacity using computer modeling shows that the system should be capable of operating within time -of -use and normally accepted criteria, with the exception of the highest residential services in Inspiration Heights. Adequate interconnection locations exist, and could be improved for automatic operation (actively connected). In addition, a SCADA headquarters office should be constructed and implemented for the ability to monitor all major water system functions — Well operation, Mann Drive PS operation and forebay water levels, SCVWD service connection flows, pressure -reducing valve operation, reservoir water levels at Mercedes and Cristo Rey sites, and interconnection flows. Water systems operation should incorporate digital readouts, electronic maps and signals to a single operator (dispatcher) at any hour of the day to alert on -call field staff in the event of ruptured mains, pumping failure, power outage, water supply outage, low reservoir water levels, etc. The Department of Public Health has strict guidelines for publicly -owned water utilities, in addition to operator registration requirements, for specific capacities within the organizational structure of a utility operation. The following is a list of capital improvement projects gathered from the research of recent documentation provided for the hydraulic analysis study that should be prioritized for the City of Cupertino's leased water system: 1. Evaluate all options to remove/reduce the City's liability associated with the low service pressures in Inspiration Heights. Potential liability could arise with water quality degradation due to the low pressures, or lack of water capacity during normal operation, and lack of fire flow capacity during emergency operations. Options could include legal agreements with each homeowner, construction of a hydropnuematic pressure zone or other closed system operation, or City purchase and maintenance of individual private pumping units. 2. Based on the Final Technical Report (SPF, January 2017), the capacity and efficiency of the Mann Drive Pump Station needs major upgrades, and may require a redesign for time -of -use operation. This should include an evaluation of the adequacy of its backup power supply. 3. Perform a complete well inspection of both Franco and Flowering Pear wells, including mechanical/material inspection, efficiency testing, and downhole video to assess the level of needed rehabilitation. 4. Investigate the cost of the two sources of City water— local groundwater and imported water from SCVWD. This should consider issues such as water quality and on -going treatment requirements of each; operation and upkeep of the conveyance systems for each; well maintenance, improvements and pumping rights; and control of its own water supply. Curiously, SJWC does not emphasize maximizing local groundwater production despite the State of California's efforts to incentivize water suppliers to use local water supplies. 5. Prepare a Water Master Plan. Water Master Plans should be the cornerstone for funding a water system. A thorough water master plan includes analysis to justify capital improvement and replacement projects that should be reviewed on an annual basis. The Water Master Plan itself should be updated at least every 10 years, or when a major update to the general plan is made. Municipal finance departments rely heavily on a water master plan to perform the necessary updates to keep its capital Improvement and replacement programs current. 6. Investigate the water quality concerns at the Mercedes Reservoir site. One of the Mercedes Reservoir site tanks was reportedly emptied approximately two years ago due to "considerations of water age and 10 quality". Water quality would be the primary concern for the method of operation currently employed by the SJWC. 7. Update the Mercedes tanks to current seismic code. According to the SPF report, both tanks may be out of compliance with seismic construction requirements. Ironically, the "General Cupertino Leased Area Description" report describes the operational practice of minimizing the water level in the tanks (maximizing Freeboard) in order to "minimize damage from sloshing during a seismic event". This is inconsistent with SJWC staff assertion that the Mercedes tank water levels are maintained between 29.5 and 32 feet, which is at or near the high water level at all times to improve service pressures for nearby residents. This represents conflicting operational goals that could be detrimental to valuable storage capacity. Additionally, operating a 2.0 million -gallon reservoir with a water level band at the highest 2.5 feet is not prudent reservoir operation and negates many of the advantages of incorporating storage within a distribution system. 8. Investigate as -built plans and the reported existence of a "logbook" that could have records of system improvements since 1916, according to the SPF report. This could provide clues to lost and paved -over old valves that have broken and fallen into the flow path of old pipelines still in operation. Such debris would be a capacity and water quality detriment to a water system, and could be a reason for the difference in computer model results and field-tested capacity. 9. Start a hydrant flushing and valve maintenance program. Hydrant flushing should include gathering hydraulic data for field verification of the computer model. Valve maintenance program should include exercising each valve, documenting turns, and inventory type, location, and size. 10. Pave the access road to Cristo Rey tank site. These capital projects represent top priority within a comprehensive Capital Improvement/Replacement Program. Additional projects should be identified through further cooperation from San Jose Water Company and candid descriptions of chronic operational challenges from staff. Otherwise, the oldest 4-inch (and smaller) "system" pipelines dating back to the 1930's and before should be prioritized for immediate replacement. If a logbook, as indicated in Item 8 above, exists it can be a very good resource for prioritization.

APPENDIX 6 Cupertino Municipal Water System Fire Flow Analysis (SJWC) Memorandum CUPERTINO MUNICIPAL WATER SYSTEM FIRE FLOW ANALYSIS Background San Jose Water Company (SJWC) provides residents of the Cupertino Municipal Water System (MWS) with high quality water and exceptional customer service. SJWC maintains and operates the MWS based on a 25-year Lease agreement, which is set to expire in less than six years on October 1, 2022. The Cupertino MWS consists of 4,183 service connections, about 58 miles of pipe, four welded steel storage tanks, five booster pumps, two wells and one regulator station. The system is comprised of three hydraulic pressure zones: Mercedes Zone, Cristo Rey Zone and Mann Regulated Zone. Imported surface water supply from Santa Clara Valley Water District (District) is the primary source of water for this system. In addition, there are two groundwater wells named Franco and Flowering Pear both located near Homestead Rd., east of Stelling Rd. District water and groundwater are both blended together at Mann Drive Station, which acts as the central hub for all three pressure zones. The City of Cupertino (City) requested from SJWC a fire flow evaluation to demonstrate that the MWS can adequately respond to a simulated fire flow event. The following sections describe SJWC's analysis and results. Analysis The Santa Clara County Fire Department has indicated that for planning purposes fire flow requirements will vary from 1,500 gpm for two hours to 2,500 gpm for two hours based on zoning. In the Cupertino MWS, the highest fire flow requirement is 2,500 gpm in proximity to schools and public facilities. Residential neighborhoods have a fire flow requirement of 1,500 gpm for two hours. Based on zoning within the Cupertino MWS and the distribution system network, SJWC determined that the area near Monte Vista High School is most appropriate to perform the requested fire flow evaluation. Should the City determine that an alternate location is preferred, SJWC will rerun the analysis. Santa Clara County Fire Department has accepted hydraulic simulations in lieu of field flows from SJWC for more than twenty years. To further demonstrate to the City the resiliency of their water system, SJWC simulated a fire flow event under normal operating conditions and a worst case hydraulic analysis based on a fire event following an earthquake. Assumptions For the fire flow simulation based on normal operating conditions, the following assumptions were made: CUPERTINO LEASED AREA HYDRAULIC STUDY H:\PUBLIC\CUPERTINOMWS_DOYLE PROPERTY\CUPERTINO TM.DOCX January 4, 2017 Memorandum • All tanks were assumed to be online • Maximum day demand conditions • The emergency pumper connection between SJWC and the MWS is offline For the fire flow simulation based on a worst case. scenario, the following assumptions were made: • Both Mercedes Station tanks are offline • Mann Station tank is offline • Flowering Pear and Franco Court wells are offline • Maximum day demand conditions • The emergency pumper connection between SJWC and Cupertino MWS is offline Mercedes Cristo Rey Station Station Mercedes Distribution Zone -W--ww� Mann r.

System Schematic for Simulated Worst Case Scenario For the worst case scenario, two hydraulic model runs were analyzed: 1) three pumps at Mann Drive Booster Station online; and 2) all five pumps at Mann Drive Booster Station online. Results There are 11 services on the southwest side of the Cupertino MWS that have static pressure below 20 psi. These homes are situated at an elevation that is very high when compared to the base elevation of Mercedes Tanks. CUPERTINO LEASED AREA HYDRAULIC STUDY 2 HAPUBLIC\CUPERTINOMWS DOYLEPROP ERTY\CUPERTINOTM.DOCX January 4, 2017 Memorandum When a fire flow event occurs near Monte Vista High School under normal operating conditions residual pressures are not significantly impacted at these high elevation homes or anywhere within in the distribution system because of the redundancy in storage and boosting facilities in the MWS. When simulating the worst case scenario with both Mercedes Tanks taken out of service, more customers on the southwest side of the leased area would either have no water or have pressure between 3 and 20 psi. To minimize the impact to customer's water pressure following this simulated event, boosters at Mann Station must be continuously operating. If all five pumps at Mann Drive Booster Station are in service, there are 15 services with no water and 19 services with system pressure below 20 psi. Due to the location of these low pressure services on a cul-de-sac, there is no potential for pipe looping. Under the simulated worst case scenario, a boil water advisory will be required for services with no water. Simulated system results during a fire flow event under normal operating conditions and a worst case scenario are presented in Table 1 and Figures 1, 2 and 3. Table 1. Number of Services with No Water or Pressure Less than 20 psi() . 2,500 gpm fire flow • Max Day Demand Mercedes Tanks; • All tanks online Cristo Rey Tank; 11 • Pumper connection with Mann Drive Booster Station SJWC offline Cristo Rey Tank; • 2,500 gpm fire flow Mann Drive Booster Station 68 33 e Max Day Demand (operating 3 pumps) • Both Mercedes tanks offline • Pumper connection with Cristo Rey Tank; SJWC offline Mann Drive Booster Station 15 19 (operating 5 pumps) (a) Under maximum day demand conditions with a 2,500 gpm fire flow demand near Monte Vista High School Summary SJWC has a long history of providing high quality water and exceptional customer service to residents in the MWS. The system is well prepared to provide adequate water supplies to the Santa Clara County Fire Department during a fire flow event under both normal operating conditions and following a catastrophic event.

San n Jose w"° EXECUTIVE SUMMARY Co Executive Summary Introduction and Purpose Pipelines are one of the most important assets of northwestern region of the Ciiy of any water system and their continual operation is + critical to San Jose Water Company (SJWC) 4,200 water services delivering reliable water supply to its customers. 2A MGD Average f • Demand With the purpose of identifying the criticality of each Neariv 60 rniles pipeline, the Planning Group conducted a Pipeline4 water storage tanks Consequence of Failure Study for the Cupertino i booster 2 wells Lease Area water system. This study provides a framework to strategically identify pipeline improvement projects within the Cupertino °Lease Area. To this end, a methodology was developed which primarily used hydraulicmodelingand flooding analysis results to .quantify the criticality of all pipelines in the water system. Consequence of Failure Evaluation Pipeline failures have a multi -faceted impact on society. In order to quantify the amount of impact a pipeline failure has on society as a whole, it was necessary to identify the primary facets affected by pipeline failures. The following four impact categories summarized in Figure ES-1 were considered to be the primary impacts. Consequence of Failure Impact Categories Health & Safety Impact on public health and safety due to possible water contamination ..ct and flooding, and in some cases due to water service outages II Transportation Impact on transportation corridors due to flooding of highways, roads, ..ct and passenger railroads System Operations Impact Impact on commercial and industrial businesses due to service outages and flooding impact on the ability to continually operate the water system and provide water to users Figure ES-1. Consequence of Failure Impact Categories Pipeline Consequence of Facture Study October 2015 Page I i -INUSan Jpaa Wata- CompEXFcuT1vE SUMMARY any Hydraulic Modeling Extensive hydraulic modeling was conducted in order to simulate catastrophic break scenarios for every pipe in. the Cupertino Lease Area water system. The hydraulic model measured the leak discharge rate out of each failed pipe, potential for water contamination due to low pressures, amount of consumer water demand inhibited due to isolation of the failed pipe, and number of valves needing to be operated to achieve hydraulic isolation for each pipe. Geographic Information System Mapping Spatial analysis played a significant part in the consequence of failure analysis. Geographic Information System (GIS) mapping was used as a tool to identify the types of properties, facilities, roads, and railroads within the potential flooding region for each pipe. in addition, GIS spatial tools were used to help identify pipelines crossing critical transmission mains and those essential for water system operations. Results from hydraulic modeling and GIS spatial analyses were input into the consequence of failure evaluation methodology, which ultimately yielded a final consequence of failure score for each pipeline. Figure ES-2 outlines the overall consequence of failure evaluation process. Figure ES-2. Consequence of Failure Score Evaluation Process Pipeline Consequence of Failure Study October 2015 Page I it San Jo- WeS Companp y EXEct1TNE SummARY Consequence of Failure Evaluation Results After the consequence of failure score was generated, aH GIS defined pipe segments in Cupertino Lease Area were uniquely ranked. from 1 to 1061 and divided into four criticality categories: High (Top 10%), Medium -High (10-20%), Medium (20-50%), and Low (50-100%). Map ES-1 provides a visual representation of the final results for all pipes by criticality category. Recommended Improvements and Actions Findings of the consequence of failure .evaluation provide a baseline for future efforts to identify and ,prioritize capital improvement projects. Main replacement and rehabilitation project recommendations take into consideration both the consequence of failure as well as the probability of failure, so those recommendations are not included in the scope of this study. However, results of this study -did bring to surface the need for a regulator installation, a valve installation; and easement documentation. As previously communicated with the City,_: S.JWG requests that the City provide more data relating to pipe type and _age _of installation before a comprehensive probability of failure analysis is conducted. Regulator Installation Based on the consequence of failure evaluation results, it is recommended that an 8-inch pressure regulator be installed on the northern border of Cupertino Memorial Park, near the intersection of Christensen Drive and Fenway Court, as shown in Figure ES-3. This improvement will preventmanyservices. from .dropping to low (often subatmospheric) pressures during a catastrophic pipe break and will increase fire -flow capacity..It is recommended that this improvement be implemented in 2017. The estimated cost for this improvement is $117,600, Figure ES-3.

This recommendation will decrease the number of large diameter valves needing to be closed to hydraulically isolate the 14-inch diameter pipe alignment on South Foothill Boulevard between Stevens Creek. Boulevard and Alcalde Road to the south. Currently, in the event of a catastrophic break along this alignment, it is estimated that approximately 2 million gallons may be discharged into the surrounding area. However, with the implementation of this recommendation, the failed pipe will be hydraulically isolated within a shorter time frame and the volume discharged will be reduced by up to 400,000 gallons. This improvement is recommended for implementation in 2017 and is estimated to cost $21,900. Figure ES-4- Recommended 14-inch Valve Installation Easement Documentation A number of pipes in the Cupertino Lease Area water system are installed within private yards and streets, see Table ES-1. SJWC requests that the City provide plat and legal descriptions, tract, parcel or utility maps identifying easement type and limits as well as water main location within each easement. This documentation would be necessary for any potential pipeline improvements in these areas. } Pipeline Consequence of Failure Study October 2015 page I v San Jana wear Company Table ES-1.

Introduction 1A Background INTRODUCTION Pipelines are a critical water distribution system asset and fundamental to virtually every facet of reliable water system operations.Given the magnitude of their importance, it is imperative that excellent pipeline asset management studies and programs be implemented to assure the safety and reliability of water systems for the overall benefit of the customers.' This Pipeline Consequence of Failure study will serve as a baseline upon which San Jose Water Company (SJWC) will develop a refined pipeline asset management program. 1.2 Objectives The objectives of the Consequence of Failure Study are summarized below: • Establish an approach for evaluating the consequence of failure for each pipeline • Locate critical facilities, features, and areas of concern • Generate results measuring the consequence of failure for each pipeline by rank Develop a baseline to help strategically identify capital improvement projects that would yield the greatest ratepayer benefit 1.3 System Overview The Cupertino Lease Area is located in the northwest region of the City of Cupertino, encompassing 3.7 square miles which is equivalent to approximately one-third of the city's total area. SJWC has been providing water service to the Cupertino Lease Area for the past 18 years as part of a 25 year agreement. The Cupertino Lease Area water system is composed of nearly 60 miles of pipelines, 4 water storage tanks with a total design storage capacity of nearly 8 million gallons, 5 booster pumps with a total design capacity of 6,300 gallons per minute (gpm), and 2 wells with a combined capacity of 1,100 gpm. The majority of water supply served to the Cupertino Lease Area comes through a Santa Clara Valley Water District (SCVWD) turnout at Mann Drive Station. There are approximately 4,200 water services within the Cupertino Lease Area, totaling an average day demand of over 2 million gallons. Map 1 provides a visual summary of the Cupertino Lease Area water system.

Pipeline Failure Event Characterization, Effects, and Mode Pipeline failure events can occur in many different fashions and magnitudes. Some failures may be as small as a minor leak, but some are catastrophic in nature causing a major disruption to the water distribution system and to the public as depicted in Figures 1 and 2. Before any system -wide analysis on the consequence of pipeline failure could be performed, it was first necessary to clearly define the characterization, effects, and mode of pipeline failures that would be considered for the purposes of this study. Figure 1. Damage observed due to main break tocated on Pensacola Drive in the eastern side of San Jose.

Workers diverting traffic on Bascom Avenue while attempting to fix amain break on a 12" water main, 2.1 Pipeline Failure Event Characterization Pipeline failure events and their impacts can be characterized by two stages. The first stage (break stage) is the affected condition of the distribution system immediately after the pipeline break, when water is being discharged from the failed pipe into the surrounding environment. The second stage (isolation stage) is the affected condition of the system while the failed pipe is hydraulically isolated and being repaired. Both stages were considered in this study to capture the entire impact of a pipeline failure event. Figure 3 includes photographs illustrating the two stages.

Picture on the left illustrates the Break Stage of a main break; picture on the right illustrates a repair during the Isolation Stage of a main break. 2.2 Pipeline Failure Hydraulic Effects (Impact Causes) When a pipeline fails, there are a few primary hydraulic effects which cause impact to the public that must be considered. During the first stage of the failure event, the additional demand (i.e. water being discharged into its surroundings) creates higher velocities and lower pressures in the distribution system. Another major failure effect during the first stage is the flooding of the surrounding vicinity. The societal impacts of low pressures and flooding that were considered in this study are explained in Section 3 Pipeline Consequence of Failure Evaluation Methodology. During the second stage of the failure event, various valves must be closed (or at least pinched down) in order to isolate the failed pipe for repair. This operation will hydraulically isolate the region contained within the closed valves and will put all of the users within this region out of service. In addition, once the isolation valves are closed, the rest of the water system outside of the isolated region may also be affected due to the change in overall system dynamics. Users outside of the isolated region may experience low pressures and reduced water flow as well. Table 1 summarizes the failure effects that were considered in this study. The societal impacts of hydraulic isolation that were considered in this study are explained in Section 3 Pipeline Consequence of Failure Evaluation Methodology. Table 1.

Failure modes include blowouts, longitudinal splits, wall ruptures/tears, circumferential breaks, joint leaks, perforations, and more. It was assumed for the purposes of this study that all pipes would fail in a catastrophic fashion resulting in complete pipe separation such that there are two points at which water is discharged at atmospheric pressure, as illustrated in Figure 4. Although the vast majority of pipeline failures in the SJWC distribution system are not of this nature or magnitude, it was appropriate to analyze a worst -case scenario for each pipeline.

Pipeline Consequence of Failure Evaluation Methodology Establishing the methodology for evaluating each pipeline's consequence of failure is the most involved and pivotal portion of this study because, in the end, methodology will determine results. Therefore, it is imperative that the methodology is developed such that it captures all key consequences or impacts that result from pipeline failures and accurately measures them. Various consequence of failure evaluation methodologies have been developed for different water utilities and for research purposes. However, upon review of various studies, it was found that a new and customized methodology was necessary to more specifically evaluate and address the particular needs within the Cupertino Lease Area. This section presents SJWC's customized methodology which is intended to provide an objective and systematized process that will yield quantifiable and justifiable consequence of failure results. The section is structured as follows: • Section 3.1 Impact Categories — Introduction to key impacts that result from pipeline failures • Section 3.2 Impact Category Measurement Parameters and Tools - Discussion of parameters and tools used to measure impacts • Section 3.3 Pipeline Consequence of Failure Scoring Methodology— Explanation of scoring methodology used to develop final rankings 3.1 Impact Categories The following four impact categories encompass what SJWC believes to be the primary societal impacts when a pipeline fails: • Health & Safety Impact • Transportation Impact Business Impact System Operations Impact The following subsections provide explanations as to why and how pipeline failures play a role in these four impact categories. 3.1.1 Health & Safety Impact The most critical societal impact of pipeline failures is related to public health and safety. Pipeline failures often create a major drop in pipeline pressures, potentially allowing contamination infiltration into pipes. According to the California Division of Drinking Water (DDW) Waterworks Standards, distribution systems are required to "assure that the minimum operating pressure in the water main at the user service line connection throughout the distribution system is not less .than 20 pounds per square inch (psi) at all times" (Chapter 16, Section 64602). However, in the event of a pipeline failure, pressures often drop below 20 psi, and sometimes even below 0 psi (atmospheric pressure) giving rise to potential contamination Pipeline Consequence of Failure Study October2015 page 17 San Jose """ CcxnPa,ny PIPELINE CONSEQUENCE ©FFAILURE EVALUATION METHODOLOGY of the water system. In addition to water quality concerns, pipeline failures can also compromise public safety due to flooding. Depending on the extent of flooding, conditions may be such that the general public is more prone to injuries. Lastly, public health and safety may be impacted due to users being put out of water service while the failed pipe is hydraulically isolated for repair. Pipeline failures can also negatively affect firefighting capabilities, However, due to the momentary nature of pipeline failures and the infrequency of fire events, fire -flow impacts during a pipeline failure were not included as part of this study. 3.1.2 Transportation Impact In densely populated areas such as the San Francisco Bay Area, transportation is a critical component of public life and is heavily intertwined with numerous societal functions. Therefore, it is essential that all corridors related to public transportation such as highways, roads, and passenger railroads be minimally disrupted. Pipeline failures, depending on magnitude and location, can cause major disturbances to transportation corridors due to flooding. 3.1.3 Business Impact Pipeline failures also negatively impact commercial and industrial businesses, possibly resulting in economic loss. When flooding occurs due to a pipe failure, all businesses that require customer or worker access may be temporarily inaccessible, thereby halting or impeding business operations. For example, potential customers of restaurants and shopping centers would be deterred from entering due to flooded conditions in parking lots, walkways, and building interiors. In addition to flooding, service shutdowns due to hydraulic isolation may also negatively affect businesses. While heavy water -consuming businesses such as restaurants, car wash stations, and certain heavy industries will be most affected, nearly all businesses will be affected as customers and workers will temporarily have only limited or no access to water. 3.1.4 System Operations lmpact There are specific pipelines that must remain in service for SJWC to maintain safe and reliable system operations. These pipelines include SCVWD transmission mains and critical pathway pipes that keep important water system facilities operational and hydraulically connected to the system. SJWC relies heavily on SCVWD for its water supply. On an average water demand day, the District treats and delivers approximately 70 million gallons of wholesale water per day to SJWC through their large transmission mains which range from 20-inches to 6.5-feet in diameter in SJWC's service area (20-inches to 48-inches within the Cupertino Lease Area). A catastrophic break in an SJWC main that crosses a District transmission main could potentially result in significant damage to SCVWD's pipeline. This could cause flooding damage and result in water supply shortages to Cupertino and other surrounding communities. Therefore, SJWC pipelines crossing SCVWD transmission mains are considered critical to system operations. pipeline consequence of Failure Study October 2015 Page 18 San Joso PIPELINE CONSEQUENCE OF FAILURE EVALUATION METHODOLOGY Company Critical pathway pipes are defined as pipelines without redundancy that keep major facilities such as tanks and pumps in operation. These pipelines typically include tank inlet/outlet pipes as well as transmission mains located upstream and downstream of pump stations. 3.1.5 Impact Categories Summary Table 2 summarizes the hydraulic effects and practical impacts which were considered in this study that correspond to the four impact categories.

Table 3 provides all of the parameters used for this study, as well as the primary tools used to obtain these measurements for each parameter. Table 3.

Therefore, all users that would experience low pressures and all properties or roads that would be flooded due to pipeline failure were accounted for according to their type. See Section 3.3 Pipeline Consequence of Failure Scoring Methodology for detail on how these critical users and facilities contributed to the overall consequence of failure score for each pipe. Pipeline Consequence of Failure Study October2015 Page 110 San Jeea wet, lcwcomp."y PIPELINE CONSEQUENCE OF FAILURE EVALUATION METHODOLOGY As indicated in Table 3, all parameters required in this study for evaluating the consequence of failure of each pipeline could be obtained through the use of the hydraulic model and Geographic Information System (GIS) mapping system. Synergi Water7r" was the tool used to measure parameters related to services experiencing low pressures following pipe breaks and outages due to isolation, while ArcGlS° was the tool used to measure parameters related to geographic location such as flooding or proximity to other features. The following subsections explain in detail how these two software tools were used to obtain measurable parameters. 3.2.1 Hydraulic Model In order to obtain results required for the consequence of failure evaluation, SJWC created an all pipes and valves hydraulic model based on GIS data. Pipe segments are assigned a unique ID in GIS and defined as a continuously drawn pipe with the same diameter and work order ID. A pipe segment is only broken by GIS at water main tees, changes in diameter, or when the work order ID changes. Pipe segments are not broken in GIS at valves, hydrants, elbows, or service taps. After importing all facilities into the hydraulic model from GIS, 1-ft resolution elevation contours were obtained from Santa Clara County and assigned to each node. Annual service demand data from SJWC's Billing Department was then geospatially plotted and assigned to the nearest node of the appropriate pipeline. Creating this hydraulic model allowed SJWC to simulate the effect caused by catastrophically breaking and then isolating each pipe segment. 3.2.2 Geographic Information System (GIS) ArcGIS® software can perform various spatial analyses and yield useful information tied to the geographic location of a specific feature. In this study, ArcGIS® was used to tie locations and attributes of each failed pipe to other external spatial data such as parcels, transportation corridors, SCVWD facilities, and population density. Flooding Buffers Following a catastrophic main break, water may inundate the surrounding area, possibly impacting critical facilities, roads, transportation corridors, businesses, and residential properties. SJWC's Distribution Systems Department identified 50-ft as the inundation limit for most pipe breaks. Therefore, 50-ft buffers surrounding each pipe were developed as potential flooding areas. When flooding intensity (see Section 3.3.1 Health & Safety Impact Category Scoring for an explanation of flooding intensity) was simulated to be greater than twice the average flooding intensity, a 100-ft flooding buffer surrounding the pipe was used as the potential flooding area. Map 2 shows the flooding buffers created around each water main. 61S Spatial Dato Spatial data related to parcels, railroads, roads and population density was needed for this study and obtained via external sources as summarized in Table 4 and illustrated in Maps 3, 4 Pipeline Consequence of Failure Study Qctober2015 Page 111 San .lox Water Company PIPELINE CONSEQUENCE OFFAILURE EVALUATION METHODOLOGY and 5. Map 3 contains parcel, road, railroad, and SCVWD pipeline data, while Map 4 shows the population density distribution. Map 5 identifies critical facilities, commercial parcels and industrial parcels. Parcels were flagged as critical in GIS if they contained hospitals, acute health care facilities, schools, and residential or commercial units where users require uninterrupted water service for dialysis or other life-support equipment.

Figure 5 provides samples of the data obtained from ArcGISO by using a 50-ft flooding buffer as an example. GIS was also used to identify water mains considered critical to SJWC's operations, as illustrated in Map 6.

First, the parameters listed in Table 3 were used to calculate scores for each impact category for every pipeline. Then scores for each impact category were weighted and combined to yield the consequence of failure score for all pipes. Figure 6 illustrates the overall scoring process.

Health and Safety Category Scoring Process and ,Equations The Health & Safety impact category score can be separated into a water quality component and a flooding component, as these are the two major impact causes associated with the general health and safety of the public. There is also a third component, the 'but of service" component which results from hydraulic isolation. However, this third component was only considered in special cases, particularly when critical facilities requiring constant water service were placed out of service. These special cases were handled separately and are further discussed throughout this subsection. The water quality component and flooding component contributed 75 percent and 25 percent, respectively, to the total weight of Health & Safety impact category score, as shown in Equation 3.1. The methodologies used to obtain water quality and flooding scores are described in the following subsections. Health &Safety ; 0.75 (Water Quality Score) + 0.25 (Flooding Score) (3.1) Impact Score Pipeline Consequence of Failure Study October2015 Page120 San Joan "'a'a` Company PIPELINE CONSEQUENCE OF FAILURE EVALUATION METHODOLOGY Water Quality Scare Service Water Quality Score For each pipe, the water quality score was determined based on the number of services that would experience between 0 psi and 20 psi, and the number of services that would experience less than or equal to 0 psi during the break or isolation stage of a pipeline failure event. Each service experiencing between 0 psi and 20 psi contributed one point to the water quality score, and each experiencing less than or equal to 0 psi contributed two points to the service water quality score, as shown in Equation 3.2 below. #of services between #of services Service Water Quality Score = 0 psi and 20 psi } + 2 { c 0 psi ) (3.2) Hydraulically isolated services that did not drop below 20 psi after the pipe break (i.e. before isolation) do not contribute to the water quality score. The rationale behind this was that hydraulic isolation does not negatively affect water quality because, although isolated services drop to 0 psi, isolation is a controlled event. Before an isolated pipeline is put back into service, the necessary protocols (e.g. flushing) will be taken to ensure only high quality water is provided to users. However, if a service elsewhere in the system that is not hydraulically isolated drops below 20 psi or 0 psi as a result of the isolation of the failed pipe, it will contribute to the water quality score. If no services dropped below 20 psi in both the break and isolation stages, the service water quality score was equal to 0. In these cases the node water quality score was considered. Node Water Quality Score_ In some cases, areas of the water system without services may experience low pressures due to a pipeline failure. Should there be contamination infiltration into these parts of the system, it is still possible for contaminated water to be conveyed toward users' services. In order to account for these potential cases, the number of hydraulic model nodes that would experience less than or equal to 0 psi were considered for the node water quality score, as shown in Equation 3.3, Only nodes with pressures at or below atmospheric pressure were included as part of the node water quality score because of the unlikelihood of water quality at a service being negatively affected due to pressures below 20 psi but above atmospheric pressure in a remote area. Any minor contamination infiltration would likely be disinfected by chlorine residual before the water reaches any service. Node Water Quality Score = # of nodes S 0 psi (3.3) Pipeline Consequence of Failure Study October2015 page 121 San JQ%Q we`"` Company PIPELINE CONSEQUENCE oFFAILUREEVALUATION METHODOLOGY Water Quality Score In cases where the service water quality score was greater than 0, the service water quality score was used as the water quality score. When the service water quality score was equal to 0 (i.e. no services were affected by low pressures), one-half of the node water quality score was used. Only a half of the node water quality score was used because, although contaminated water may be introduced into the system at atmospheric or sub -atmospheric conditions, the chlorine residual may disinfect the contaminated water in the time it would take to reach users services. Equation 3.4 shows the process for determining the water quality score. After a water quality score was calculated for atl pipes, the scores were scaled such that the maximum score was equivalent to a value of 1. ( Service WQ Score , Service WQ Score > 0 Water Quality Score = j x (Node WQ Score), Service WQ Score = 0 (3.4) z Critical Facilities Pipes affecting critical facilities by lowering their service pressures below 20 psi due to a pipe break had their scores elevated to the maximum water quality score of 1. In addition, pipes that took critical facilities out of service during the isolation stage were also given the maximum water quality score of 1. Although isolation is not typically a water quality concern, because it is a serious overall health concern for critical facilities requiring constant water service, it was considered a reasonable cause for score inflation. Flooding Score For each pipe, the flooding score was determined based on estimated flooding intensity and population density of the estimated flooded area. Estimated Flooding Intensity Flooding intensity resulting from a pipe break is difficult to approximate as it is dependent on numerous factors. However, it can be roughly approximated as a function of the discharge rate of the pipe break and the time it takes to isolate the failed pipe, as shown in Equation 3.5. Flooding Intensity = (Discharge Rate) x (Time Until Isolation) (3.5) The discharge rate for each pipe break was attained from the hydraulic model (see Section 3.2.1 Hydraulic Model), and the time required to respond to and isolate each failed pipe was approximated based on the pipeline emergency response procedures and practices of SJWC's Field Service and Distribution Systems Departments. Pipeline Consequence of Failure Study October2015 Page 122 $anpany Jose avatar PIPELINE CONSEQUENCE OFFAX URE EVALUATION METHODOLOGY Com Typically, when SJWC is notified of a water leak, it may take a Field Service worker up to 45 minutes to respond and arrive at the site of the break for investigation. If the Field Service worker is able to close the valves by hand (i.e. when valves are not larger than 8-inch gate valves or 12-inch butterfly valves), then it will usually take up to 10 minutes to close each valve. However, if valves cannot be closed by hand (e.g. larger valves) the Field Service worker will contact the Distribution Systems Department to have a truck dispatched. It may take up to 45 minutes for the truck to arrive onsite, and it may take up to 15 minutes to close each of the remaining valves, The flow chart used for deciding the approximate required time for isolation is shown in Figure 8.

However, if takes longer for Field Service to close the smaller valves than it does for the distribution System truck to be dispatched and close the larger valves, then the time it takes to close the smaller valves should be used. Figure 8. Estimated Time Required for Isolation Flow Chart Population Density Flooding occurrences in densely populated areas will have a greater impact on general public safety. The average population density associated with each pipe was estimated based on the intersection of the population polygons and the flooding buffer of each pipe. See Section 3.2.2 Geographic Information System (GIS) for more detail on how the population density for each pipe was estimated. Pipeline Consequence of Failure Study October 2015 Page] 23 San Jns Waas any p III cwnPIPELINE CONSEQUENCE OFFAILURE EVALUATION METHODOLOGY Com Flooding Score The flooding score for each pipe was calculated by multiplying estimated flooding intensity by the logarithm of the estimated average population density in the vicinity of the pipe, as shown in Equation 3.6. The logarithm of the population density was used for a more even distribution. After the flooding scores were calculated for each pipe, they were scaled such that the maximum flooding score was equivalent to a value of I . Flooding Score = (Flooding Intensity) x log(Population Density) (3.6) Critical Facilities Pipes affecting critical facilities due to flooding had their scores elevated to the maximum flooding score of 1_ 3.3.2 Transportation Impact Category Scoring The Transportation impact category is a large contributor to the overall consequence of failure score, accounting for 20 percent of the total weight. The score for this impact category is calculated solely based on flooding of public transportation corridors. The City of Cupertino categorizes their road types similarly to the United States Department of Transportation Federal Highway Administration's classifications. Table 5 tabulates the City of Cupertino road types along with their estimated Annual Average Daily Traffic (AADT). The AADT is defined as the total volume of vehicle traffic in a year divided by the number of days in a year, in units of vehicles. A map provided by the City of Cupertino with the AADT values for major roads is included in Appendix B.

This allows for a fair comparison between the two datasets and more representative relative values. (2) The United States Department of Transportation Federal Highway Administration provides general AADT ranges for various road classifications. In order to determine the amount of impact each pipeline failure would have on public transportation, flooding areas for each pipeline were geospatially plotted and overlaid with roads and railroads (see Section 3.2.2 Geographic Information System (GIS) for more detail on flooding areas). Each pipe was given a score equivalent to the AADT value of the highest traveled road affected by the pipe. For example, a pipe affecting both an arterial and a major collector would receive a score of 35,800. One exception, however, was that only half of the AADT value for freeways was taken into account because of the unlikelihood of flooding both sides of freeways with center dividers. After the transportation corridor scores for all pipelines were assigned, scores were scaled so that the maximum score was equivalent to a value of 1. Passenger Railroads Pipes that affected passenger railroads due to flooding were given the maximum score of 1. Although passenger railroads would likely not affect as many people as freeways, the impact would be great because trains are typically unable to take alternate routes to get to their destinations, and any railroad damage could require extended repair times.

This impact category score takes into account pipelines that are necessary for the continual operation Of the water system, Pipes that cross SCVWD transmission mains were considered critical to the overall operations of the water system, as SJWC relies heavily on these transmission mains for water supply; these pipes were given a score of 1. In addition, critical pathway pipes without redundancy that are essential for the operation of pumps or tanks were also given a score of 1. Table 6 presents the scoring summary for the system operations impact category. See Section 3.1.5 System Operations Impact Category Scoring for more information on the System Operations impact category. Table 6.

Business Impact Category Scoring Process and Equations Out of Service Score The Out of Service score, which is a measure of business impact due to a water service outage, was based on inhibited demand. The inhibited demand is equivalent to the average day demand (in gpm) of the services placed out of service, which can also be understood as the amount of water that would have been used by businesses had there been no service outage. The equation used for the Out of Service score is as follows, in Equation 3.7: Out. of Service Score =log Commercial and Industrial + 1� (3.7) Inhibited Demand A small number of commercial and industrial services with very high demands create a skewed and uneven demand distribution. Therefore, the logarithm of the demands was used for a more even distribution. A value of 1 was added to the demand before the logarithm was taken in order to avoid negative Out of Service scores and also to ensure that pipes which did not affect Pipeline Consequence of Faitura Study October 2015 Page 127 San Jose co PIPELINE CONSEQUENCE OF FAILURE EVALUATION METHODOLOGY 4"o- commercial or industrial demands would receive a score of 0 (i.e. !og(0+1)=0). After the scores were obtained for each pipe, the results were scaled such that the maximum value was equal to a value of 1. Flooding Score The flooding score for the business impact category was equivalent to the number of commercial and industrial parcels affected. A parcel was considered affected if it was at least partially within the flooding region of the pipe_ Equation 3.8 presents the equation used to calculate the flooding score. . #of Commercial and Industrial Flooding Score = Properties Af f ected (3.8) After the flooding scores were obtained for each pipe, results were scaled such that the maximum score was equivalent to a value of 1. Business Impact Category Score The overall Business impact category score is equivalent to the weighted sum of the Out of Service score and the flooding score for each pipe. The Out of Service score was given a 60°% weight, and the flooding score was given a 40% weight. The flooding score was given a lower weight than the Out of Service score because of the higher degree of uncertainty with flooding. In the event of a pipe break, there is uncertainty as to where the break will occur along the pipe, and there is also uncertainty as to the exact destination of the discharged water. Nevertheless, because a large flooding scenario would leave a relatively long-term negative impact on businesses, a weight no lower than 40% was considered appropriate. Equation 3.9 is the equation used to obtain the overall Business impact category score for each pipe. Business Impact = 0.6 (Out of Service Score) + 0.4 (Flooding Score) (3.9) Category ,Score After the scores for each pipe were calculated, they were scaled such that the maximum score was equivalent to a value of 1. Freight Railroads Railroads exclusively used for freight transport are critical to numerous industries requiring the transport of goods. Because pipes that impact freight railroads due to flooding would have a large impact on many businesses, they were given the maximum business impact category score of 1.

Pipeline Consequence of Failure Evaluation Results 4.1 Results for Overall System Every pipeline in the Cupertino Lease area was evaluated according to the methodology explained in Section 3.3 Pipeline Consequence of Failure Scoring Methodology and ranked based on the calculated consequence of failure scores. Pipes with identical final scores were prioritized according to their flooding intensities. Results were grouped into four criticality categories as shown in Table 7. Figure 10 shows the breakdown of the four criticality categories by pipe count and by pipe segment length. Table 7.

Recommended Improvements and Actions The results and findings of this study are intended to provide a baseline to help with future efforts to identify and prioritize pipeline capital improvement projects. !Definitive main replacement and rehabilitation projects are not included as part of this study. SJWC requests that the City of Cupertino provide more pipe type and age of installation data before a comprehensive probability of failure analysis is conducted for the development of definitive pipeline improvement projects. However, the results of this study did bring to surface the need for a regulator installation, a valve installation, and easement documentation. 5.1 Regulator Installation for Mann Regulated Zone Mann Regulated Zone is located within the northeast portion of the Cupertino Lease Area. Although most pipes within Mann Regulated Zone do not affect any critical facilities, key features, or businesses, nearly all of them fell within Medium -High and Medium criticality categories. The cause of these results is that h4ann Regulated Zone was designed with only one regulator station as the sole .input into the zone. Therefore, when there is high demand in the zone due to fire flows or a pipeline failure, nearly all. services in the regulated zone drop to very low pressures, often to subatmospheric pressures, regardless of which pipe fails. Therefore, SJWC recommends an 8-inch pressure regulator be installed on the northern border of Cupertino Memorial Park, near the intersection of Christensen Drive and Fenway Court. This improvement will prevent many services from dropping to low pressures in the event of a pipeline failure and will also increase fire -flow capacity to help meet current fire department flow requirements. Figure 13 shows the location of the proposed 8-inch regulator in relation to Mann Regulated Zone, and Figure 14 shows the regulator in relation to its immediate vicinity. This improvement is recommended for implementation in 2017 and is estimated to cost $117,600.

Recommended 8-inch Pressure Regulator and Immediate Vicinity Pipeline Consequence of Failure Study October 2015 Page 134 San Jose Water Cprnpeny REcOMMENDED IMPROVEMENTS AND ACTIONS 5.2 Valve Installation A 2,200-ft long, 14-inch diameter pipe alignment on South Foothill Boulevard between Stevens Creek Boulevard and Alcalde Road requires 7 valves to be closed to achieve hydraulic isolation, 4 of which are greater than or equal to 12 inches in diameter. In the event of a catastrophic break anywhere along this alignment, it is estimated that approximately 2 million gallons could be discharged into the surrounding area. However, with the installation of a 14-inch valve at the intersection of South Foothill Boulevard and Stevens Creek Boulevard, only two valves greater than or equal to 12 inches in diameter will need to be closed, thereby decreasing the time required to hydraulically isolate the alignment and reducing the volume discharged by up to 400,000 gallons. Therefore, it is recommended that a 14-inch valve be installed as illustrated in Figure 15. This improvement is recommended for implementation in 2017 and is estimated to cost $21,900. Figure 15. Recommended 14-inch Valve Installation 5.3 Easement Documentation It was found that a number pipelines within the Cupertino Lease Area cross through private property yards and streets. SJWC requests the City of Cupertino provide documentation defining the limits of the easements, as they would be necessary for any potential pipeline improvements in these areas. Map 8 highlights the location of these pipelines and Table 8 lists APN's and addresses of parcels that intersect these pipelines.

Evaluate and record high and low levels. ✓ Check and record fluoride concentration in the distribution system. ✓ Collect routine bacteriological samples and test for total coliform. Follow up on unsatisfactory sample results and provide a report documenting the results. ✓ Check service pressures throughout distribution systems and investigate the cause of any low pressures. Flush dead ends or low flow sections of the system to maintain water quality. ✓ Conduct distribution system maintenance and keep records of all preventive work, repairs, and equipment modifications or replacements Annually ✓ Evaluate overall performance of the distribution system (e.g., pressure, flow capacity) and identify areas needing repair or update. ✓ Exercise distribution system valves and clean valve pots. Record inspection results and repair broken valves. Locate (i.e., GPS coordinates) unmapped valves and add to the City's GIS system. ✓ Do a water audit and calculate unaccounted-for water by comparing water production and usage — goal of < 4%. ✓ Conduct a preventive maintenance program (e.g., calibration, replacement) on high volume service meters. Replace 5% to 7% of lower flow meters beginning with earliest installations. ✓ Evaluate safety programs and equipment (e.g., traffic safety, trench safety, confined space, ladder safety) and update training documents as needed. ✓ Evaluate Emergency Response Plan (e.g., loss of pressure, contamination, cross connections, overfeeds) and update as needed. ✓ Update/reconcile distribution system data (e.g., year of install, size, type, material, condition) in GIS or other asset management software to reflect the latest capital projects and repairs. ✓ Evaluate the flushing program (e.g., training, equipment, availability of hydrants or blowoffs). ✓ Have backflow prevention assemblies tested by certified backflow assembly tester (BAT). Record results and take corrective maintenance as needed. Ensure backflow inventory is up to date by reconciling with new construction and remodels in the service area. ✓ Determine daily and monthly peak water -demand periods. Document peaks for next five- year master plan update. ✓ Conduct Cross -Connection Control Program activities according to your program plans. ✓ Perform flow tests on 20% of fire hydrants. Pumps and Pumping Facilities Daily ✓ Check motors for unusual pump motor conditions, such as: • Unusual pump noises in operation (hum, chattering, clicking, rapid knocking, etc.) • Motor fails to start or to come up to speed normally. • Blackened or excessive sparking at commutator or brushes. • Fine dust under couplings with rubber butters or pins. • Smoke or charred insulation. • Excessive vibration, heat, unusual odors. ✓ Check any warning lights or alarms for low pressure, pump failure, intrusion, power outage, etc. Correct issues or write work order for follow up corrective action. ✓ Check pumps for leaks or seepage for pumps that are not water lubricated. Write work order for follow up corrective action for any leaks found. ✓ Check pump cycle rate - troubleshoot excessive pump cycling (about 6 cycles per hour). ✓ Verify start and stop pressure settings and operability of water pressure gauges - reference O&M manual. Reset if out of parameters. ✓ Check bearing temperatures if a temperature gauge is available. Take care when checking how hot it may be. Write work order for follow up corrective action. ✓ Check pump run hours if information is available. ✓ Clean pump station interior and grounds. Report wear, vandalism, and/or security concerns for follow up corrective action. Monthly ✓ Check oil or grease lubricant reservoirs for proper levels and any leakage or unusual conditions. Write work order for follow up corrective action if unable to correct problem. ✓ Check packing for wear and repack as necessary. ✓ Check pump and motor alignment to ensure torque transfer to the pump. Adjust as needed. ✓ Check and secure all pump mountings. ✓ Inspect bearings and drive belts for wear. Adjust, repair, or replace as necessary. ✓ Perform routine operation of emergency generator per manufacturer's instructions. ✓ Check condition of emergency generator batteries, fuel levels, oil levels, instruments, and controls. Correct conditions outside of parameters or write work order for follow up corrective action. ✓ Check that existing pressure gauges, pump run meters, and flow meters are functioning properly. ✓ Check that pump controls are functioning properly. Write work order for follow up corrective action. ✓ Check pump station lighting, ventilation, security, and animal proofing (bats, birds, rodents). Write work order for follow up corrective action. ✓ Read electric meter at pump house and record. Annually ✓ Clean electrical panels and MCCs. Inspect connections for burning, pitting, discoloration. Replace worn or damaged components. ✓ Perform pump efficiency tests on well and system pumps. Schedule maintenance or replacement when efficiency fall below establish levels of service. ✓ Performed by a qualified electrician, twice per year or every 400 hours (whichever is less), service the emergency generator and test the automatic transfer switch at Mann Station ✓ Measure source pump capacity in gallons per minute (GPM) to detect pump output problems. ✓ Calibrate pressure gauges and flow meters monitoring pump performance and capacity. Storage Facilities Weekly ✓ Check any warning lights or alarms - low water level, high water level, intrusion, power outage, etc. Correct issues or write work order for follow up corrective action. ✓ Check storage tank for signs of security breaches - damaged fences, open gates, graffiti, vandalism, etc. Report security violations. ✓ Check the overflow line, vents, ladder access locks, roof access hatches, and controls that are readily visible from the ground for damage, vandalism, or other conditions. Correct issues or write work order for follow up corrective action. ✓ Check storage tank and site after any adverse event (i.e., heavy rain, high wind, earthquake). Correct issues or write work order for follow up corrective action. Monthly ✓ Check water level indicator and record information. ✓ Verify all openings are protected from surface runoff, windblown contaminants, insects, birds and animals. Correct issues or write work order for follow up corrective action. ✓ Check tank overflow lines for signs of damage, such as, screens, flapper valves, check valves, splash plate, etc. Correct issues or write work order for follow up corrective action. ✓ Check area for excessive vegetation or dangerous conditions - uncut grass, brush, dead trees, fire hazard, ponding water, etc. Correct issues or write work order for follow up corrective action. ✓ Check control valves for proper positions, open or closed.
