Driver – Senate Bill SBX7-7 Water suppliers to increase water use efficiency

Urban Water Conservation Reducing per capita 10% by December 31, 2015 Reducing per capita 20% by December 31, 2020

Effective 2016 urban retail water supplies not meeting water conservation requirements are not eligible for State water grants and loans

The recycled water program assists in meeting this requirement

Background – 2011 and 2012

• Feasibility study approved by SWRCB• Reviewed 17 Alternatives• Narrowed down to Alternative A-6, MBR

plant near Oak Grove Drive at 0.25 MGD recharge at John Muir High School

• Two Firms hired to develop then review regulations and costs

• Costs dropped based on less purple pipe

Quantified Benefits

Recharge Recycled Water: 280 AFY

Other Recharge: 38 AFY average

• Estimated Stormwater Capture: 15 AFY

• Estimated Urban Runoff Capture: 23 AFY

Barren Land: Half Acre Improvement

Energy Savings: 600 Megawatts

• Enough for 85 Southern California homes annually

Hydrogeologic Model• 3 areas modeled:

– Athletic fields– Flint Creek Wash– Behind Devil’s Gate Dam

• Results:– All 3 alternatives achieve CDPH minimum of

four months retention time from active wells.– All alternatives do not exceed the RWC of 20%

over a 120-month period.
