Smart Irrigation Program (S.I.P.) (Direct Installation Program) June 3, 2011: Board of Public Utilities

RPU Water Use Efficiency  Mandates  AB 1420 - Best Management Practice (BMP) compliance for grant eligibility  SBX7-7 - 20% per capita water savings by 2020  RPU Advantages  Preserve water resources  Meet state mandates for water use efficiency  Generate revenue from excess water sales

The Smart Irrigation Program “SIP” • A multi year Smart Irrigation Controller and High Efficiency Nozzle Direct Installation Program • Program is FREE to approved customers • RPU staff will engage high water users

High Efficiency Sprinkler Nozzles Traditional Spray Head High Efficiency Spray Head   Easy to install Better defined edges   Less run off Retrofits multiple brands   Save 1,300 gal/year More Uniform Coverage 37,357 / 35,599 IEUA WMWD 101,152 42,117 143,269

“Smart” or Weather Based Irrigation Controllers (WBICs) Smart Controllers/WBICs are more efficient:  Real-time local weather data  Historical weather patterns  Pre-programed watering schedules/restrictions  Plant type Can save up to 20% of water used instantly!  Soil Type  Slope/Sun considerations

The Smart Irrigation Program “SIP”  Potential savings analysis performed before audit/install approval  Three year program targets:  Year 1 – top 5% water users  Year 2 – top 10% water users  Year 3 – top 20% water users

The Smart Irrigation Program “SIP” STEP 1 – Initial Site Visit  Qualified customers will receive a certified water audit from a licensed RPU contractor  Assess irrigation system  Feasibility of controller install  Feasibility of high efficiency nozzle install S S S SS SZSSSSSSSSSSSSSS

The Smart Irrigation Program “SIP” STEP 2 – Installation Visit  Installation of smart controller/WBIC and high efficiency sprinkler nozzles  Audit results/data used to program smart controllers  Audit inventories used to ensure correct nozzles obtained for install

The Smart Irrigation Program “SIP”  Program Projections:  Estimated cost per site $600-$800  Estimated 700 sites installed over 3 year program  Estimated average water savings of 20% per site

Recommendations That the Board of Public Utilities recommend that the City Council:  Approve the Smart Irrigation Program;  Approve funding in the amount of up to $200,000 for F/Y 2011-12 and inclusion in the budget for the following two (2) fiscal years; and  Authorize the City Manager, or his designee, to make any minor, non-substantive changes necessary to implement this program.
