TAIrI3 DRAFT URBAN WATER MANAGEMENT PLAN supplies to greatly improve the water reliability of existing customers and allow for new development without compromising that improved reliability. Given the increases in cost of San Francisco water, recycled water will also eventually cost less in relative terms. The City already has a small pilot project running and has completed the planning and environmental review of a larger water recycling system. Water conservation is another important water source. "Passive conservation" occurring from the adoption of State and Federal plumbing codes mandating the sale of high - efficiency toilets and clothes washers (that account for about half of total residential indoor water use) will achieve about 965 acre -feet of water savings per year by 2020. Passive conservation will occur over time without any City action or expense. The question for the City is how much "active conservation" is warranted? The City has a potential implementation plan of active conservation programs that could save from 500 to 800 acre -feet of water per year. Water savings for most programs, however, have limited lifetimes. This is especially true for toilet and clothes washer programs that accelerate water savings in the near term, but eventually would be achieved via passive conservation. Hence, the timing of water savings is important to consider, as different programs can achieve different flows of results. From an institutional and long -term perspective, the Master Water Sales Contract with the City and County of San Francisco (via the SFPUC) is scheduled to expire July 1, 2009. The City should aim to renegotiate the terms of the contract so that it improves its water supply reliability. This may be accomplished via the newly formed Bay Area Water Supply & Conservation Agency (BAWSCA) that is based on enabling legislation signed into law by the Governor in the fall of 2002.
