I c/// I I i Executive Summary i ES.1 Background Redwood City (the City) is 100% reliant on one source of potable water supply, the San Francisco Hetch Hetchy regional water system. Currently, the City is consuming approximately I 1,000 acre-feet per year (AF/yr) over the contractual (wholesale) supply assurance of 12,243. AF/yr. The Redwood City Water Use Forecast for 2000 to 2020, dated June 20, 2002 (prepared by John Whitcomb, PhD), includes water supply projections associated with future housing, i employment, and population, etc. The Water Use Forecast explores future water supply scenarios including the "worst case" scenado that excludes any water conservation and a scenario that takes into account passive water conservation. The potential water supply i savings associated with an active water consen/ation scenario are addressed in the City's Urban Water Management Plan. Based on these forecasts and planning, the City will need additional water supplies to meet both current and future needs. i The City has four options to reduce current demands on the Hetch Hetchy supply, in order to comply with the supply assurance and provide supply for future growth: i 1. Negotiate water transfers from other agencies that use the Hetch Hetchy regional system . i 2. Negotiate a new source of potable water supply via the regional system ("wheeling") 3. Implement water conservation measures I 4. Implement a water recycling program for landscape irrigation and industrial uses This study builds upon the joint recycled water pilot project being operated in Redwood Shores i by the South Bayside System Authority (SBSA) and the City, and.on the Water Recycling Feasibility Study for the Redwood Shores Area (Kennedy/Jenks Consultants, January 22, 2002). ES,2 Market AsseSsment I Three ge0graphicaJ areas within'the City were reviewed relative to providing a new market for recycled water Use. The areas generally include Redwood Shores, the "Greater Bayfront Area" and C~eqtral R(~dwood City. potent a recyc ed water uses are primarily for landscape irrigation in RedwoOd Shor6s and Central Redwood City. Some industrial uses, and potential for nterna i uses such as toilet flushing, exist primarily in the Greater Bayfront area and, to a lesser extent, Central Redwood City.
