Part of EBMUD’s Strategic Plan

Goal: Ensure a reliable high quality water supply

for the future

Strategy 1 Preserve current entitlements and augment the District’s

successful water supply projects by obtaining supplemental

supplies to meet annual customer demands

Strategy 2 Reduce potable water demand through water conservation

and build on past water savings to help ensure a reliable

water supply

Strategy 3 Reduce potable water demand through water recycling and

build on past success to achieve a diversified and reliable

water supply

Bay Area Regional Reliability

(BARR)

Eight Bay Area water agencies

working together on regional

solutions to improve water

supply reliability

MOA signed in 2015

Obtained USBR WaterSMART

funding for Drought

Contingency Plan (DCP)

Includes “Task Force” of 25

stakeholder groups

(environmental, public policy,

wastewater, regional

planning) that review and

comment

29

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

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

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

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

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

35

• 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

Freeport Supplies

36

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

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

concept to lead to a project

implementation plan and MOA

• Sacramento River Settlement

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
