IRWD Projects with Met Funding
Regional Benefits from Met Funding Local Projects:
1. Defers Met’s need to construct and operate new
water supply projects;
2. Reduces region’s reliance
on imported supplies; and
3. Improves supply diversity for local water agencies:
 Potable Water Supply Projects
 Recycled Water Program
 Water Use Efficiency
11
IRWD Projects with Met Funding
Potable Water Supply Projects:
• Dyer Road Well Field Seasonal Shift Program
 Incentivized IRWD to pump wells during MWD peak usage periods
 From 1988 through 2008, total LRP funding: $15 million
• Irvine Desalter Project Potable Treatment Plant
 New local water supply: 63,000 acre-feet of treated groundwater
 From 2006 through 2027, estimated LRP funding: $15 million
• Wells 21 and 22 Desalter Project
 New local water supply: 121,000 acre-feet of treated groundwater
 From 2012 through 2037, estimated max LRP funding: $30 million
12
IRWD Projects with Met Funding
IRWD Recycled Water Program
• Michelson Water Recycling Plant – LRP1
 Assisted IRWD to develop RW production: 3 MGD to 13 MGD
 From 1986 through 2011, 186,000 acre-feet of recycled water
 Incentive at $154 per AF; total LRP Funding: $29 million
• IRWD Water Recycling Plants – LRP2
 Assisted IRWD to develop RW production: 13 MGD to 18 MGD
 From 2005 through 2030, 131,000 acre-feet of recycled water
 Incentive at $117 per AF; estimated LRP funding: $15 million
Conversion: 1,000 AF per year = 0.9 MGD
13
IRWD Projects with Met Funding
Water Use Efficiency Initiatives
• Met Incentives to IRWD from 2005 through 2012:
 Residential Incentives: $1.3 million
 Commercial Incentives: $3.1 million
• Met funding incentives based on Met’s avoided cost.

• Cost-Effective
Programs
 Incentive at $154 per AF
 Funded through Met’s Water Stewardship Fund ($43 per AF)
 Met incentives leveraged by IRWD at average of $225 per AF
• “Lifetime” Water Savings = 19,000 acre-feet
• On-going program.
