- 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

17. Regulatory Changes
•Metering, Graywater,
•Lead removal, and more…

18. 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

19. EBMUD Water Supply
Management Program
(WSMP) To 2040

20. 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

21. 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

22. WSMP 2040 Solution
Provides 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%

23. 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

25. 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

26. 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

29. WSMP 2040 - Water Conservation
Approach
• 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. Customer Opinion Research
(April – August 2011)
• Awarded $131K DWR
grant
• Conducted focus groups,
web survey, facilitated
meetings
• Researched
– drought behaviors
– WCMP strategies and
services

38. Customer Opinion Research
Findings
• 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
