DRAFT URBAN WATER MANAGEMENT PLAN Redwood City will be required to reduce water use by 17.5 %. By one estimate, the probability of Redwood City having to reduce water use by 17.5% or more is 10.1 %. Moreover, the City's water reliability is deteriorating. As total water demands on Hetch Hetchy grow, water shortages will increase both in frequency and in magnitude. In addition, the system yield has been reduced by the 2002 order from the State Division of Safety and Dams to draw down Calaveras Reservoir in Alameda County to only 30% of its capacity. This represents a loss of about 25% of the total Bay Area storage capacity in the system. 2. Wholesale Water Costs The cost of SFPUC water is projected to increase by 188% by FY 2011 -2012 because of significant new costs associated with the SFPUC's recently adopted Capital Improvement Program (CIP). That CIP forecasts about $2.9 billion in investments to the regional water system to strengthen it against collapse during earthquakes, meet federal and state drinking water standards, and improve its robustness from an engineering perspective. The decreasing reliability and increasing wholesale cost and issues are linked, as both motivate the City to develop alternative sources. With such large increases in purchased water costs, alternative supplies and water conservation programs become relatively more cost - effective. In early 2002 the City Council added three items to the `A' list of its priorities, all concerning water supply: I. Address Redwood City water supply assurance 2. Regional water supply — Fix the Hetch Hetchy system 3. Implement a water recycling project On April 1, 2002, the City Council held a study session, in which they: • Reviewed and discussed a draft Capital Improvement Program budget, reflecting their priority list, and recommended by the City Manager • Reviewed and discussed a feasibility analysis of each priority prepared by staff. No changes were made to the three water supply priorities. The City Council ultimately approved a Capital Improvement Program budget for Fiscal Year 2002/03 in June, 2002, which included necessary appropriations to advance each priority. Water recycling is a feasible alternative, as presented to the City Council in two engineering feasibility studies in 2002 The wastewater treatment plant operated by the South Bayside System Authority (SBSA) in the Redwood Shores area of Redwood City produces high quality effluent that can be further treated and used for landscape irrigation and some industrial applications. Using recycled water would free up potable water 3 Water Recycling Feasibility Study for the Redwood Shores Area, Submitted by Kennedy /Jenks Consultants, January 22, 2002 and Water Recycling Feasibility Study for Redwood City, Submitted by Kennedy /Jenks Consultants, August 7, 2002.
