.A5 <br /> <br />Executive Summary <br /> <br />ES.1 Background <br /> <br />Redwood City (the City) is 100% reliant on one source of potable water supply, the San <br />Francisco Hetch Hetchy regional water system. Currently, the City is consuming <br />approximately 1,000 acre-feet per year (AF/yr) over the contractual (wholesale) supply <br />assurance of 12,243 AF/yr. The Redwood City Water Use Forecast for 2000 to 2020, <br />dated June 20, 2002 (prepared by John Whitcomb, PhD), includes water supply <br />projections associated with future housing, employment, and population, etc. The <br />Water Use Forecast explores future water supply scenarios including the "worst case" <br />scenario that excludes any water conservation and a scenario that takes into account <br />passive water conservation. The potential water supply savings associated with an <br />active water conservation scenario are addressed in the City's Urban Water <br />Management Plan. Based on these forecasts and planning, the City will need additional <br />water supplies to meet both current and future needs. <br /> <br />The City has four options to reduce current demands on the Hetch Hetchy supply, in <br />order to comply with the supply assurance and provide supply for future growth: <br /> <br /> 1. Negotiate water transfers from other agencies that use the Hetch Hetchy regional <br /> system <br /> <br /> 2. Negotiate a new source of potable water supply via the regional system <br /> .

I .m,plement,@ ~v.a,ter recycling program for landscape irrigation and industrial uses <br /> <br />This study builds upon the joint recycled water pilot project being operated in Redwood <br />Shores by the South Bayside System Authority (SBSA) and the City, and on the Water <br />Recycling Feasibility Study for the Redwood Shores Area (Kennedy/Jenks Consultants, <br />January 22, 2002). <br /> <br /> ES.2 'Market Assessment <br /> <br /> Three geographica~ areas within the City were reviewed relative to providing a new <br /> market for recycled water use. The areas generally include Redwood Shores, the <br /> "Greater Bayfront Area" and Central Redwood City. Potential recycled water uses are <br /> primarily for landscape irrigation' in Redwood Shores and Central Redwood City. SOme <br /> industrial uses, and potential for internal uses such as toilet flushing, exist primarily in <br /> thie Greater Bayfront area 'and, to a lesser extent, Central Redwood City. <br /> <br /> Water Recycling Feasibility Study for Redwood City <br /> <br /> <br />
