From Drought Response to Center Stage

  1. 1. From Drought Response to Center Stage:Water Conservation Finds It’s Home in Integrated Resources PlanningCentral Texas WaterConservation Symposium Richard HarrisFebruary 26, 2013 Water Conservation Manager
  2. 2. Presentation Outline• EBMUD Facts and Figures• California’s Water Challenges• EBMUD’s Water Supply Management Program• EBMUD’s Water Conservation Master Plan Implementation Strategies
  3. 3. EBMUD Facts and Figures
  4. 4. EBMUD Service Area
  5. 5. EBMUD Water Supply• The watersheds – Water quality – Water storage• Size matters
  6. 6. EBMUDWater and Wastewater Services Water • 1.34 million customers • 190-210 MGD demand • 35 communities • 330 sq.mi service area • >4,000 miles of pipe • 385,000 accounts Wastewater • 650,000 customers • 75 MGD Avg. Flow • 83 sq.mi service area • 100% energy sufficient

  14. 14. Challenge: Zero Sum Game• Competition between Water Agencies for limited supplies Legal Decisions 1957 Plan• Competition between Agencies and Environmental Clean Water Concerns for water Ac t e Climate Chang Endangered• Desire to protect Species water quality/habitat & fisheries
  15. 15. Challenge: Climate Change Could Impact California’s - Snowpack - River Flow - Fisheries Habitat (warmer water) - Delta Levees - Water Quality (particularly in the Bay Delta) - Water use patterns - Groundwater Quality - Drought (severity and frequency) - Floods (severity and frequency) - Hydroelectric Power Generation
  16. 16. Regulatory Changes •Metering, Graywater, •Lead removal, and more…
  17. 17. Urban Water Management Planning Act - 1983• EBMUD sponsored legislation• Evaluates supply reliability in drought years and emergencies• Provides public input in shaping water resources planning• Verifies water supply assessments for new developments• Supports basis for State Water Plan• Complies with Water Conservation Act of 2009
  18. 18. EBMUD Water SupplyManagement Program (WSMP) To 2040
  19. 19. WSMP 2040 Purpose/Objectives• Water supply reliability to the year 2040• Account for accomplishments and changes since the last WSMP (1993), including: - New facilities and programs - New regulatory and resource requirements - Climate change• Find optimum balance between customer rationing, conservation, recycling and supplemental supply• Maintain environmental stewardship
  20. 20. WSMP 2040 Planning Objectives• Operations, Engineering, Legal & Institutional - Provide water supply reliability - Utilize water right entitlements - Promote regional solutions• Economic - Minimize customer cost - Minimize drought impact - Maximize positive impact to local economy• Public Health, Safety and Community - Ensure high water quality - Minimize adverse sociocultural impacts - Minimize risks to public health & safety - Maximize security of infrastructure & water supply• Environmental - Preserve & protect the environment for future generations - Preserve & protect biological resources - Minimize carbon footprint - Promote recreational opportunities
  21. 21. WSMP 2040 SolutionProvides Flexibility for the Future• Future demand growth will be met through: - Aggressive water conservation - Maximum feasible recycled water - 10% water rationing objective in dry years• Additional diverse supplemental supplies will allow reduction in water rationing from >25%
  22. 22. WSMP 2040 - Preferred Portfolio • Robust plan: needed in light of future uncertainty (e.g., Global Climate Change) • Multiple, parallel project components • Diverse & flexible strategy • Environmentally sound

  24. 24. 2040 Demand Study• Employed a land-use based approach to develop water use estimates• Land-use approach viewed as the most rigorous methodology• Actual water use data by land use was utilized• Met with 19 city and county land use planning agencies to confirm planning projections
  25. 25. 2040 Demand Study Results• Higher density, development up not out• 0.8% annual increase in demand (2010-2040)• Demand reflects planning agencies’ best estimate of development• Demand confirmed by population projections• Future increase in demand entirely offset by conservation, recycling and rationing in dry years
  26. 26. 2040 Demand Projection withConservation & Recycling
  27. 27. SBx7-7 Interim & Compliance 2020Per Capita Use Targets 10-year (1995-2004) Baseline = 165 GPCD 5-year (2003-07) Projected 2020 133 Conservation Baseline = 158 GPCD And Recycling 144 GPCD
  28. 28. WSMP 2040 - Water ConservationApproach• Considered more than 100 conservation measures• Analyzed 53 individual conservation measures beyond plumbing codes• Range of analysis: from natural savings to maximum voluntary conservation potential• Assess technology, behavior and leak repair• Assess implementation barriers (e.g. customer acceptance, market saturation, cost)• Range of market saturation <1% to 95%

  37. 37. Customer Opinion ResearchFindings• General perception that low water price limits conservation-related financial savings• Function, price and water savings are important purchasing considerations• Outdoor landscape is an extension of living space, aesthetics and usability• Few customer know how much water they use; measured in dollars, not gallons• Ability for landlords to individually meter, bill for usage could provide conservation incentive• Many expressed interest in metering technology, real time access, water budgets
