6.1E Page 9 rates for its wholesale customers in addition to addressing water supply and water shortages for the regional water system. The Master Contract expires on June 30, 2009. The Master Contract provides for a 184 million gallon per day (mgd) "Supply Assurance" to the SFPUC's wholesale customers, subject to reduction in the event of drought, water shortage, earthquake, other acts of God, or rehabilitation and maintenance of the system. The Master Contract does not guarantee that San Francisco will meet peak daily or hourly customer demands when their annual usage exceeds the Supply Assurance. The SFPUC's wholesale customers have agreed to the allocation of 184 mgd Supply Assurance among themselves, with each entity's share of the Supply Assurance set forth on a schedule adopted in 1993. This. Supply Assurance survives expiration of the Master Contract in 2009. Water SUDDlv Contract between Citv and Countv of San Francisco and the Citv of Redwood Citv (Auaust 1984). Redwood City, along with 27 other Bay Area water suppliers, signed the Settlement Agreement and Master Contract with San Francisco in 1984. The Master Contract is supplemented by an individual Water Supply Contract; Redwood City signed the individual contract in 1984 and it also expires in 2009. Redwood City's contracted Supply Assurance from the SFPUC is 12,243 af/yr. Over the fast ten years, the City consumed an average of 700 af/yr over the contractual amount; the City is able to purchase this additional supply from the SFPUC because other entities do not use their full contractual supply. The City and the Bay Area Water Supply and Conservation Agency are expected to renegotiate its contracts with San Francisco prior to expiration in 2009. Recycled Water Supply The Redwood City Council approved a recycled water project in 2003 with the goal of reducing demand on the San Francisco Regional Water system. The City's recycled water system, which is operational and currently being extended, consists of treatment, disinfection, and pumping facilities at the South Bayside System Authority (SBSA) wastewater treatment plant in Redwood Shores, and pipeline distribution and customer retrofit facilities in the Redwood Shores, Bayfront, and Seaport areas east of Highway 101. The SBSA and Redwood City entered into agreements for the production and distribution of recycled water that is treated to the California State Title 22 standards for non-potable unrestricted use. The recycled water can be used for landscape irrigation, industrial applications, and other approved indoor uses such as toilet flushing in new commercial and residential buildings. The recycled water system has been designed to deliver up to 1,995 af/yr by 2030. Current demand on the recycled water system is approximately 260 af/yr. tn 2008, the City Council of Redwood City adopted a Recycled Water Use Ordinance and established a Recycled Water Service Area. The Stanford in Redwood City Project site is not within the adopted Service Area; as a result, the Service Area would need to be expanded and a transmission system would need to be constructed for the use of recycled water in the Stanford in Redwood City Project. Groundwater supply Groundwater is not a source of potable water supply for Redwood City because of water quality, reliability, and long-term production capacity concerns. Local groundwater is currently used by a limited number of private well owners for domestic and irrigation uses. The City does not include groundwater as a source of supply in its 2005 UWMP. Summary of Current and Planned Water Supplies Table 2 identifies the existing and planned water supplies available for Redwood City from 2005 to 2030 in five-year increments. Page 6 of 11
