1 The Metropolitan Water District of Southern California May 30, 2013

2 Regional Water Wholesaler to 6 counties 5,200 square miles 26 Member Agencies ~18 million residents Regional economy: ~$1 trillion Estimated Retail Demand: 4 million acre-feet Provide about ½ of retail demands

3 Bay/Delta LA Aqueduct Colorado River Aqueduct State Water Project Sierra Mountains Local Groundwater and Recycling Conservation

8 25% Colorado River supplies 30% State Water Project (flowing through the Delta) 45% Local Supplies Los Angeles Aqueduct Conservation Recycling Groundwater Desalination 8

9 20% Reduction in Per-Capita Water Use Water Use Efficiency Develop Incentives and Partnerships Implement Foundational Actions Local Resources Delta Improvements for Reliability SWP Develop Dry-Year Supply Programs CRA Blueprint for Adapting to Change

10 20% Reduction in Per-Capita Water Use Water Use Efficiency Develop Incentives and Partnerships Implement Foundational Actions Local Resources Delta Improvements for Reliability SWP Develop Dry-Year Supply Programs CRA Blueprint for Adapting to Change What Does This Mean? Stabilize Imported Supplies Increase Efficiency and Local Resources What Does This Mean? Stabilize Imported Supplies Increase Efficiency and Local Resources

11 Heavy dependence on imported supply and SWP Diversions Emphasis on Conservation, Local Supplies, and Storage & Transfers

12 Local Storage Diamond Valley Lake Mathews Lake Skinner Conjunctive Use Groundwater DWR State Project Reservoirs Central Valley/SWP Storage San Luis Carryover Semitropic Arvin-Edison Kern Delta Mojave CRA Storage Advance Delivery Lake Mead ICS

13 14x Increase in Capacity

14 14 Conservation: 900,000 af/yr Recycling: 335,000 af/yr Groundwater Recovery:111,000 af/yr Seawater: 46,000 af/yr (planned) Conservation represents regional actions both active & passive Recycling & groundwater represents total regional production 2012 (MWD & member agency) Seawater represents 3 planned local projects

15 15 $1, ,500+/AF $ ,500/AF $1, ,500+/AF $1, ,300/AF Local Supply Avg. ~ $1,500/AF SWP Existing ($650/AF) + Delta Improvements ($200/AF) = ~ $850/AF is committed to meeting future additional Metropolitan is committed to meeting future additional water supply needs through local resources and conservation Revised: December 18, 2012

17 17 Metropolitans share ~ 25% Includes work completed by the BDCP Steering Committee effort Exports will be minimal for 1.5 to 3 years following an earthquake

18 Objectives Improve export quality to meet Public Health standards & reduce treatment costs Support actions to minimize salinity imports Meet 500 mg/l blending goal Some Basin Plans have low TDS objectives Could restrict extended recharge of high salinity Colorado River water * OrangeCounty Main San Gabriel Raymond Chino San Jacinto 18 Las Posas Cucamonga Warner Valley Elsinore Upper San Juan San Mateo & San Onofre Six Basins SylmarSylmar VerdugoVerdugo East San Fernando Fernando *Some of the highlighted basins do not currently receive MWD recharge supplies

19 Users pay – new conveyance & associated mitigation Beneficiaries pay – habitat conservation & other state-wide benefits Average cost for Southern Californians ~ $5 - 6/month per householdImprovementsCapital Annual O&M Funding Source Conveyance$14 billion$83 millionWater Contractors Eco-Restoration & Other Stressors $3.6 billion$46 million Fed/State/Water Contractors/Other 19 Metropolitans share is approximately 25 percent The $14 billion estimate per the Governors announcement (July 25, 2012) Other cost information from Dec-2010 BDCP document

20 BDCP Delta Facilities San Francisco PUC Hetch Hetchy Project Repairs to protect against future seismic events, and to meet current building codes and drinking water regulations Contra Costa Water Districts Los Vaqueros Project Improves water quality and provides emergency storage 20 BDCP Economic Benefits and Financial Strategies, SCWC/The PFM Group, February 2012

21 MWD share of BDCP Cost MWD Diamond Valley Reservoir/Inland Feeder projects Primarily an emergency storage facility but also provides drought and water quality benefits SDCWA Emergency Storage Project Enhances reliability of the water supply of San Diego in the event of seismic disruption 21 BDCP Economic Benefits and Financial Strategies, SCWC/The PFM Group, February 2012

22 Delta is critical to Californias water supply Southern California is committed to conservation and local supplies for future growth and diversification 1.1 MAF of conservation and local resources will be developed to meet future needs Storage has been developed to manage big gulp/little sip Stable imported supplies are needed for reliability
