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

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.
