30 Bay Area Regional Reliability (BARR) cont d Draft DCP identified 15 potential drought mitigation projects - Interties, storage, advanced treatment for new supplies, water recycling, and changes in water management practices that do not require new infrastructure Seeking additional USBR WaterSMART funding for a Regional Water Marketing Program - $750,000 over three years to pilot regional transfers/exchanges - Develop a roadmap document to help facilitate future transfers/exchanges 30

31 Los Vaqueros Reservoir Expansion Project CCWD, Bureau studying expansion from 160 to 275 TAF EBMUD participating in environmental review Several possible scenarios for EBMUD participation - During wet years, EBMUD sends Mokelumne water to LV in exchange for an option during droughts - EBMUD wheels water through Freeport to LV for the project partners - No commitment; still determining benefit for EBMUD participation 31

32 Local Groundwater Stewardship & Leadership Sustainable Groundwater Management Act (SGMA) - In November 2016, EBMUD became Groundwater Sustainability Agency (GSA) for the portion of the East Bay Plain that underlies its service area - In February 2017, Hayward City Council authorized GSA application for the portion underlying its service area Next Steps - Preparation of single Groundwater Sustainability Plan for entire East Bay Plain (due in 2022) 32

33 Bayside Groundwater Project Bayside facility allows EBMUD to inject treated potable water into the aquifer during wet years for extraction in dry years Constructed in 2010, but not used due to dry conditions 2017 conditions allowed EBMUD to make test injections, beginning in February 33

34 SJC-EBMUD Groundwater Demonstration Project Current Status - Application for groundwater export permit filed with County - Supported by Advisory Water Commission in February - County Hearing in April Next Steps - Finalize Operations and Funding Agreements - Water rights - Detailed design - Construction - Operation in FY20 Dam (Existing) Mokelumne River NSJWCD Pump Station Pump Irrigation (Drip Emitters) 2.8 miles New Pipe Booster Pump NSJWCD Pipeline (Existing) Water Filter Pixley Slough Well ( gpm) Road Crossing (Multiple) Stream / Ditch Crossings (Multiple) Water Treatment Water Tank Mokelumne Aqueduct 34

35 Freeport Regional Water Project Drought Lessons Learned Advance planning and investment paid off: 1/3 of customer demand was met in 2015 by Freeport CVP supplies are less reliable, especially in consecutive dry years Water transfers can meet more EBMUD needs than originally expected Short-term transfers are very difficult to implement on short schedules. As much as possible, start transfer permitting the prior year Long-term transfers offer greater certainty, advance permitting, and less price risk 35

36 Freeport Supplies Freeport Goals Preserve and maximize Central Valley Project (CVP) deliveries Supplement water supply short falls with long-term transfers Use short-term transfers when necessary after maximizing CVP and long-term transfer deliveries Consider use of capacity by others 36

37 Preserve and Maximize CVP Deliveries EBMUD s unique CVP contract - Dry years only, EBMUD entitled to take up to 133 TAF - EBMUD s 2015 supply was cut by 75% Work with USBR on M&I Water Shortage Policy to improve CVP supply reliability Continue to advocate for EBMUD on Coordinated Operations Agreement (COA) modifications, Reinitiation of Consultation on Long-Term Operations, and other CVP activities Folsom Lake - January 16, 2014 Folsom Lake - February 9,

38 Placer County Water Agency (PCWA) Long-Term Water Transfer PCWA Executed MOU in August Amending MOU to include variable water pricing based on water-year type Purchased 17,000 AF of short-term supply in 2014 and 2015 Working on developing long-term water transfer agreement PCWA is conducting modeling and environmental reviews for EIR 38

39 Additional Long-Term Water Transfer Partnerships Yuba County Water Agency - Developing long-term transfer concept to lead to a project implementation plan and MOA Sacramento River Settlement Contractors - In 2015, EBMUD purchased 13 TAF of short-term transfer water - Working with several individual water agencies to develop longterm agreements Sycamore Mutual Water Company Reclamation District No 1004 Anderson Cottonwood Irrigation District 39

40 Key Strategies for Long-Term Water Supply Plan for uncertainty (drought, climate change, regulatory uncertainty) Lock in customer conservation levels and maximize the effectiveness of conservation dollars Water recycling program expands and plans for potential future potable reuse Regional partnerships to diversify supplies and improve reliability Sustainable groundwater management with local partners Long-term water transfers to backstop CVP short falls 40
