Potential Changes due to Climate Change
Supply• Changes in timing and
quantity of precipitation in the Sierras
• Sea level rise could increase sea water intrusion into the Delta, decreasing amount of time surface diversions are suitable quality
Demand• Increased air temperatures
could increase outdoor demands
• Changes in local precipitation could change water demands
• Changes in development could change water demands
Contra Costa County Climate Leaders Workshop October 2013
Water Management Strategies
• Increase Conservation• Increase Water Recycling/Reuse• Diversify Supply Portfolio• Acquire New Supplies
Contra Costa County Climate Leaders Workshop October 2013
Water Conservation Act of 2009 (SBX7-7)
20% reduction in per capita water use by the year 2020
Each urban retail water supplier must develop water use targets by July 1, 2011 and the following must be included in the UWMP: • Baseline daily per capita water use • 2015 interim water use target • 2020 water use target

CCWD SBX7-7Interim and Compliance Water Use
• Additional plumbing code savings• Continued conservation programs• New conservation programs
• CII • Fixtures• Landscape
• Recycled water
EBMUD SBX7-7Interim and Compliance Per Capita Water Use
Baseline = 165 GPCD
10-year (1995-2004)
Projected 2020Conservation
And Recycling144 GPCD
• Baseline = 165 GPCD
• Min. 5% 2020 Target = 150 GPCD
• Calc. 2020 Target = 175 GPCD
• UWMP Target = 150 GPCD
• 2015 Target = 158 GPCD
• Suppressed demand during drought recovery will help achieve 2020 water use target.
• Projected demand goal in 2020 lower than 2020 water use target.
Use Less, Conserve More
CCWD Conservation Program• Water use evaluations• Rebates• Water budget• Educational materials
EBMUD Conservation Program• Water use evaluations• Rebates• Water budget • Grey water/Rain water• Landscape ordinances

CCWD Conservation Services
Contra Costa County Climate Leaders Workshop October 2013
• Indoor Water Use Evaluations– Review all indoor water use– Identify inefficient fixtures– Provide recommendations for replacement or repair
• Landscape System Evaluation– Review existing watering schedule– Inspect sprinkler system– Provide site-specific watering schedule and set controller with
customer– Provide site specific recommendations for improving long term
water use efficiency
• Rebate Program– Lawn to garden conversion– High efficiency toilets and clothes washers– Smart Irrigation Timers– Commercial devices and fixtures
• Water Budgets– Site specific estimate of landscape water demand– Compare weekly meter readings to ensure use is on budget
EBMUD Conservation Program
Contra Costa County Climate Leaders Workshop October 2013
• Indoor Water Use Evaluations– Indoor water use surveys– Commercial/Industrial water use surveys– Provide recommendations for equipment upgrades
• Landscape System Evaluation– Landscape water surveys– Landscape water budgets– Leak detection– Landscape irrigation upgrades– Landscape ordinances– Graywater/Rainwater harvest
• Rebate Program– High efficiency toilets, clothes washers, dish washers– Smart Irrigation Timers– Commercial devices and fixtures
Recycle and Reuse
CCWD Service Area• Central Contra Costa Sanitary
District– Concord/Pleasant Hill
landscape irrigation– Future Concord Naval Weapons
Station development• Delta Diablo Sanitation District
– Pittsburg/Antioch irrigation– Dow wetlands– Power plants
• Current Use: ~ 9 mgd• Future Use: ~ 14 mgd
EBMUD Service Area• North Richmond Water
Reclamation Plant & Richmond Advanced Recycled Expansion– Industrial boilers & cooling
towers at Chevron refinery• San Ramon Valley Recycled
Water Project– Irrigation
• Current Use: ~ 7.6 mgd• Future Use: ~ 20 mgd (by 2040)

Diversify Supply Portfolio
Contra Costa County Climate Leaders Workshop October 2013
EBMUD Future Drought Supply Portfolio
Note: Customer rationing limited to 15%
Acquire New Supplies
• Purchase imported water from other parties– Sept 2013 EBMUD & CCWD successfully completed a one time transfer
from Woodbridge Irrigation District
• Pump more groundwater– Cities of Brentwood, Pittsburg pump their own groundwater– Bay Point receives groundwater from Golden State Water Company– Oakley receives groundwater from Diablo Valley Water District
• Develop groundwater banking conjunctive use programs
• Obtain/increase water rights for local streams• Desalinate surface or groundwater
– Bay Area Regional Desalination Project has completed site specific analyses of a possible facility at Mallard Slough Intake
