concrete floor slab within a building without
prior approval of the Administrative Authority.
When approved, such piping shall be installed in
accordance with the following requirements:
(The Sections 609,3,1 and 609.3,2 remain as per
current code text)
Findings
1. Most of the surface soils in the Silicon Valley
are relatively young and unconsolidated
sedimentary materials formed from a wide
variety of parent materials, the varying chemical
composition, degree of weathering, and the
relatively acid environment have created soils of
varying types, which are particularly corrosive in
nature,
2, Much of the surface soil in the Silicon Valley
is highly expansive (i,e., shrink-oswell behavior)
and have low bearing strength.
There are two types of expansive soils in the
area:
a. The organic silty clays which are
from the recent bay muds.
b. The plastic silty clays which weather
from the shale found in the hills surrounding
Santa Clara Valley,
3, The local climate is characterized by
markedly delineated rainy and dry seasons,
which tend to maximize the expansive
characteristics of soil.
4. Some parts of the Silicon Valley have hard
water, which is corrosive to ferrous pipe,
5. The groundwater table is unusually high in
many places,

6, The Silicon Valley is in a highly active
seismic area.
16,20.060 Backwater Valves
1994 OPC Section 710.1 is amended to read as
follows (deleted language is lined through and
new language is underscored):
(a) Drainage piping serving fixtures which have
flood level rims located below less than twelve
(12) inches (3048mm) above the elevation of
the next upstream manhole and/or flushin~ inlet
cover at the public or private sewer svstem
serving such drainage piping shall be protected
from backflow of sewage by installing an
approved type backwater valve, Fixtures above
such elevation shall not discharge through the
backwater valve, unless first approved by till;
Administrative Authority
Findings
The Silicon Valley topography includes
mountainous and foothill areas with intennittent
steep slopes, Also, Silicon Valley is located in a
seismically active area, which increases the
likelihood of breakage of building sewers and
laterals, leading to an above average potential of
sewage back-up into buildings without adequate
protection.
16,20.070 Cleanouts
1994 OPC Section 719 is amended by adding
Subsection 7 as follows:
719,7 Cleanouts shall be installed at the property
line where the private sewer system connects to
the publicly-maintained sanitary sewer lateral.
All such line cleanouts shall be extended to
grade with materials and according to
specifications approved by the Administrative
Authority and tenninate within a concrete box,
Findings
The Silicon Valley soils are expansive in nature,
These expansive soils create unstable conditions
which increase the potential of breaks in sewer
laterals, To maintain sanitary services, it is
necessary to gain access, to periodically maintain
public sanitary laterals, This is accomplished by
the additional cleanout as required above,
16,20.080 Condensate Disposals
1994 OPC Section 807,2 is amended by
replacing it with the following:
Condensate from air-cooling coils and comfort
cooling equipment not intended to be used for
the storage or holding of food or drinks shall be
collected and discharged to an approved point of
disposal acceptable to the Administrative
Authority.
Tennination of such drains shall be made by an
air break. Condensate drain lines in sizes 1 1/4"
and larger shall be assembled using approved
drainage pipe and fittings. Condensate waste
water shall not drain over or upon a public way,
sidewalk, pedestrian ramp or the like,
Condensate drains within the interior of a
building shall not be connected to the building or
drain or overflow piping systems, The waste
pipe shall have a slope of not less than 1/8 inch
per foot and shall be of approved corrosion.
resistant material not smaller than the outlet size
as required below for air-cooling coils or
condensing fuel-burning appliances,
respectfully,
Condensate wastes pipes from air-cooling coils
shall be sized in accordance with equipment
capacity as follows:
EQUIPMENT CAPACITY
Up to 20 tons of refrigeration
21 to 40 tons of refrigeration
4i to 90 tons ofrefrigeration
91 to 125 tons of refrigeration
126 to 250 tons of refrigeration

The size of condensate waste pipes may be for
one unit or a combination of units, or as
recommended by the manufacturer, The capacity
of waste pipes assumes a 1/8 inch-per.foot slope,
with the pipe running three-quarters full.
Condensate drain sizing for other slopes or other
conditions shall be approved by the
Administration Authority,
