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

Background - 2012• Cal Poly Pomona began working on
project in August 2012 – Field of Green• IRWMP process began in September
2012• November 2012 Board authorizes
proceeding with hydrogeologic evaluation, CEQA Plus, and Program Management services and payment of fee for grant application

Background - 2013• January 2013 - Board adopted resolution
regarding WaterSMART Grant• March 2013 - Board authorized consulting
services for conceptual report for Title 22• March 2013 - Draft groundwater recharge
regulations changed • April 2013 - Labor Compliance resolution
adopted by Board• April 2013 - Board approved amendment to
hydrogeologic modeling agreement for two other modeling runs

Recycled Water Flow
13
Benefits of Recycled Water Project Enhance local supply and reduce dependency on
imported water
Reduction in greenhouse gases and energy usage
Demonstrate watershed approach to developing
local supplies and benefitting the community• Water Education
• Watershed Integrity and Health
• Public Outreach
Support of stakeholders – city, school, church,
Sanitation Districts, County Public Works5/20/2013
14
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.

CEQA Plus
• Initial Study to be distributed June via FMWD website, via email notice to Board packet distribution list which includes newspapers and blogs, public agencies, other entities
• Workshop will be scheduled for 30 days from release of document
• Recommended action at August Board meeting

Title 22 – Conceptual Report
• Conceptual Report drafted on May 9, 2013• Provides:
– Summary key requirements or topics, – References to Title 22 and FMWD method of
compliance• All items are achievable - no fatal flaws
with the project

Raymond Basin Management Board
• Originally stormwater and urban runoff to be captured was to be credited to account
• RBMB has stated no longer able to provide 100% credit
• RBMB willing to provide some capital contribution
