2 Water Customers Daly City Hayward Palo Alto San Jose

3 SFPUC Service Area Demands San Francisco Retail Demand FY demand 78 mgd 96% from SFPUC Regional Water System supplies 4% from groundwater Wholesale Customer Service Area FY demand mgd 64% from SFPUC Regional Water System supplies 12.8% from groundwater 3% from recycled water 3.4% from surface water 15.9% from other sources 3

4 Wholesale Customer Supply Limitation 2009 Water Supply Agreement places a supply limitation on the wholesale customers and San Francisco to encourage conservation and use of alternative supplies SFPUC does not implement conservation programs in the wholesale service area Bay Area Water Supply and Conservation Agency has implemented conservation programs to benefit the wholesale customers Individual UWMPs describe conservation activities for wholesale customers 4

21 Non-Residential Assistance Variety of assistance Surveys and plan review Large project partnerships Indoor equipment retrofit grant Launched Jan 2012 Fixed saving projects & custom retrofits 21

22 Example Large Partnership Projects NASA Ames and Moffett Field (completed 2012) Survey and rebates for replacement of 965 old toilets and urinals with water efficient models; also provided over 12,000 watersaving aerators and showerheads Moscone Center (completed 2012) Survey and rebates for replacement of 190 toilets and 99 urinals Civic Center (in progress) Direct install of toilet, urinal, and fixture replacements in five buildings thru EPA grant funding SF Housing Authority 38 Buildings (completed 2012) Survey and rebates for replacement of over 1,100 toilets; also provided over 12,000 water-saving devices 22

23 Large Landscape Assistance Seven projects awarded through grant program since 2009: Sunset Boulevard (6.5 blocks), complete Nov 2011 Alta Plaza Park, complete Dec 2012 Jefferson Park, complete Dec 2012 Balboa Park, complete Dec 2012 Fort Mason, complete 2013 Laguna Honda Hospital, complete 2013 Alamo Park, planning to start early 2013 Eleven large landscape audits through technical assistance program since 2011 a 23

24 Large Landscape Grant Example: Sunset Boulevard Before: Sunset Blvd is a main thoroughfare that runs north/south through the Sunset District. Center medians and side aprons consisted of weeds/turf, uneven irrigation coverage, broken and plugged pop-up spray heads, overspray, and a maintenance challenge due to the high-traffic area. Grant Amount: $1,239,644 Estimated Water Savings: AFY 24

25 Sunset Boulevard After After: SFPUC provided grant to retrofit 6.5 blocks with native Bentgrass, low-precipitation heads, new irrigation controllers, rain and soil moisture sensors and gopher barrier. CA native Bentgrass expected to use 40% less water Project Status: Complete; educational signs to be posted 25

26 Jefferson Square Park Before Before: 4.8 acre park in Western Addition. Existing park was all turf with antiquated irrigation system that resulted in uneven irrigation coverage causing brown spots. Grant Amount: $1,063,980 Estimated Water Savings: 6.57 AFY 26

27 Jefferson Square Park After After: Entire park renovated with a new irrigation system. CA native no-mow on the upper slopes, new turf replacing highly used quadrant area, and 30,000 square feet of low-water use plants replacing turf on the perimeter of the park. Project Status: Bids opened 1/11/12 - $200,000 under budget!; Construction starting April 27

28 Community Irrigation Meter Grant Helps urban agriculture and community gardens manage irrigation water use Waives SFPUC fees for installation of a new dedicated irrigation water service connection and meter Provides sites annual water budget based on square footage of the irrigated landscape Applicant must pay water bill 4 applications received since Dec 2011 launch, 3 meters installed to date 28

29 Small Landscape Assistance Educational materials and supplies Trainings Demonstration garden Plan review 29

30 Residential Graywater for Outdoor Irrigation Laundry to landscape pilot Design manual Workshops Onsite tech assistance Kit of parts 95 applications, 56 kits sold since 2011 Permit fee rebates 30

31 Education and Outreach School Ed State standards aligned curriculum Classroom presentations Science center Field trips Outreach Water supply Program participation Fix a leak! 31

32 Where We Anticipate Water Savings Moving Forward Clothes Washer Incentives Toilet Incentives Other Fixtures (showerheads, urinals, prerinse spray valves) Large Nonresidential Indoor Retrofits This is an estimate based on projections from the 2010 model update thru 2035 and doesn t account for actual measure activity through 2012; in the 2010 update, several measures (such as toilet direct install) were shown as running for many years past beyond when they will actually end with the assumption that a replacement measure would take its place ; this should only be used for very general purposes with caveats that it was our best estimate in 2010, will evolve over time, and its difficult to accurately predict over a 25-year period 32
