- 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
Regulatory Changes
•Metering, Graywater,•Lead removal, and more…
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
EBMUD Water Supply Management Program
(WSMP) To 2040
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
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
1 Estimated range of multiple measures/products across all customer sectors.2 Preliminary number based on need for water in 3 of 10 years. Baseload unit costs subsequently reduce by approx. 60%.
Content Overview:Projected 2040 Water Supply
Note: Customer rationing limited to 15%
2011 Water Conservation 2011 Water Conservation Master Plan (WCMP) Update Master Plan (WCMP) Update
• Update to 1994 WCMP
• Internal planning-level document
• Ten-year period 2011-2020
• Incorporates long-term planning to year 2040
• Obtains customer input through surveys, focus
groups, facilitated meetings, and workshops
