Challenge: Zero Sum Game

• Competition between Water Agencies for limited supplies

• Competition between Agencies and Environmental Concerns for water

• Desire to protect water quality/habitat & fisheries

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)

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

• Environmental- Preserve & protect the environment for future generations- Preserve & protect biological resources- Minimize carbon footprint- Promote recreational opportunities

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%

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

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

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

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%

Water Conservation (Market) Trends

• Indoor residential conservation becoming saturated

• Focus toward outdoor and supply-side savings

• Maintaining savings through behavior-related services

• Innovative incentives thru loans, on-bill financing

• Standards for advanced metering infrastructure

• Nexus with energy, wastewater, and solid waste

• Enhanced web-based services (self-help tools, videos)

• Professional landscaper & plumber certification

Customer Opinion Research Customer Opinion Research (April (April –– August 2011)August 2011)

• Awarded $131K DWR grant

• Conducted focus groups, web survey, facilitated meetings

• Researched

– drought behaviors

– WCMP strategies and services

Customer Opinion Research Customer Opinion Research FindingsFindings

• 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
