Technical Memorandum <br /> <br />To: Peter Ingrain, RWC Public Works Services Director <br />From: John B. Whitcomb, PhD, Consultant <br />Date: August 15, 2002 <br />Subject: RWC Water Supply Reliability <br /> <br />This technical memorandum presents my analysis of the water supply and demand balance for <br />the City of Redwood City (RWC) water system. Assessing water demand/supply reliability can <br />be useful in supporting a variety of water planning functions including: <br /> <br /> Assessing the merits of an expanded recycled water system in Redwood Shores and <br /> subsequent proposed phases in the Greater Bayfront and Central Redwood City. <br /> <br /> [] Determining the availability of water for new developments under new state laws adopted <br /> via Senate Bills 221 and 610. <br /> <br /> ~ Assessing the need for expanded water conservation programs and/or other new water <br /> supplies. <br /> <br /> [] Understanding and developing drought response actions to match thc risk accepted by thc <br /> City in purveying water to its customers. <br /> <br />The discussion of water supply reliability is described in following four sections: <br /> 1. SFPUC water supply <br /> <br /> 2. RWC Water demand <br /> <br /> 3. Reliability: thc water supply and demand balance <br /> <br /> 4. Selecting a proper level of reliability <br /> <br />1. SFPUC Water Supply <br /> <br />RWC currently purchases 100% of its potable water supplies from the San Francisco Public <br />Utilities Commission (SFPUC). The SFPUC serves as a wholesaler of water f~om the Hetch <br />Hetehy Water and Power System. To quantify the future reliability of water supplies from this <br />source, I consulted the following three sources of information: <br /> <br /> [] San Francisco Public Utilities Commission (SFPUC) Water Supply Master Plan, April <br /> 2000. <br /> <br /> <br />
