Slide 6AD1 If we have a complete history would be good to see if our use dropped in 2015 then rose back up? I can dig into some of the data to see if we have that complete annual history. That might be more illustrative than picking out just 2013, 2019, and 2020Andre Duurvoort, 7/14/2021
Water Conservation Measures for Municipal Water Use• City Ordinance 15.32 – Water Conservation• 2015 Water Conservation Measures• Partnered with Valley Water and water retailers to offer rebates (Graywater - Laundry to Landscape, Landscape Conversion and Rainwater Capture)• Achieved 31% below 2013 consumption baseline during 2015 drought event
