<br />6. I ð- ¿,G <br /> <br />2.1.4 <br /> <br />Additional Conservation Measures <br /> <br />2.1.4.1 Pre-Rinse Spray Nozzles <br /> <br />Recommendation: Install water-efficient pre-rinse spray nozzles in dishwashing facilities of <br />restaurants, cafeterias, and other food service providers. The Task Force estimated 50% <br />market penetration, resulting in a potable water reduction of 33 af/yr. <br /> <br />Status: Redwood City began participation in the state-wide Pre-Rinse Spray Valve Installation <br />Program, coordinated and administered by the California Urban Water Conservation Council. A <br />total of 77 spray valves have been installed in Redwood City eateries, providing an estimated <br />potable demand reduction of 14 af/yr. <br /> <br />Work Plan Next Steps: Redwood City will renew its participation in the state program for Fiscal <br />Year 2005/06, with the goal of installing an additional 150 pre-rinse spray valves with an <br />estimated potable water demand reduction of an additional 26 af/yr. <br /> <br /> <br />2.1.4.2 Evapotranspiration Controllers <br /> <br />Recommendation: Install evapotranspiration (ET) controllers on landscape irrigation systems for <br />irrigation-only water customers. The Task Force estimated that this program would reduce <br />potable water demand by 46 af/yr. <br /> <br />Status: This recommendation has not yet been implemented. Staff's approach to implementing <br />the Large Landscape Irrigation Efficiency Program (know as BMP No.5 within the California <br />Urban Water Conservation Council's recognized conservation practices) is to first focus site <br />owners and managers on seasonally adjusted irrigation scheduling, based on a monthly water <br />budget unique to the site and its conditions. Equal emphasis is placed on basic system <br />inspection and repair, so that water is not being wasted due to broken spray heads and/or <br />leaking pipes. <br /> <br />Work Plan Next Steps: The City will implement a pilot program for residential sites in FY <br />2005/06. ET controllers will be installed on five large residential landscape systems with a total <br />estimated potable water demand reduction of 5 af/yr. User evaluations and performance results <br />will be tracked for future decision-making. <br /> <br />Redwood City Recycled Water Project <br />Progress Report 2005 <br />Redwood City Recycled Water Task Force Recommendations - Final Report <br />p:\pw-proj\2004\0468025 rwc recycled retrofit & support svcltask 11 program supportltask force status report\final reportlprogre.. report on tt recommendations_final.doc <br /> <br />Page 14 <br />
