$,/6-7 Section 1: Introduction 1.1 Background Redwood City (the City) is 100% reliant on one source of potable (drinking) water supply, the San Francisco Hetch Hetchy regional water system. Currently, the City is consuming approximately 1, 100 acre-feet per year (af/yr) over the contractual (wholesale) supply assurance of 12,243 af/yr. Since 2001, the City has been studying the feasibility of using disinfected tertiary recycled water for landscape irrigation, industrial applications, and other uses allowed by Title 22 of the California Code of Regulations. Studies showed that implementing a recycled water program, in conjunction with an aggressive conservation program, would enable the City to eliminate its potable water supply deficit by 2010. In August 2003, Redwood City Council approved a broadly-defined and flexible recycled water project to help the City achieve its goal of reducing demands on the Hetch Hetchy system. Also in August 2003, City Council created the Community Task Force on Recycled Water (Task Force). The objective of the Task Force, in summary, was to identify ways to reduce drinking water demand by 2,000 (af/yr) in a financially feasible manner that would give the City alternatives to using recycled water at schools and playgrounds. The Task Force focused on solving the City's water supply and demand imbalance by the year 2010. The Task Force presented its recommendations to City Council via the Recycled Water Task Force Report, dated March 3, 2004 and City Council accepted the Task Force recommendations on March 22, 2004. 1.2 Purpose The Task Force Report requested that City staff prepare annual reports on the City's progress toward implementing the recommendations presented in the Task Force Report and that these annual reports are made available for City Council and public review. This is the first Annual Status Report on Task Force Recommendations. 1.3 Potable (Drinking) Water Deficit Summary The City continues to track its overall progress in eliminating its potable water deficit by the year 2010. Table 1 provides a summary of the potable water demand and deficit history over the past 6 years. The demands reflect annual variations due to weather, implementation of increasingly 'active' conservation measures, and commercial building occupancy. The deficit increase from 2002/2003 to 2003/2004 was due to a two-week period of extremely hot weather at the end of the winter, which triggered irrigation demand almost a month earlier than normal. It is reasonable to assume that in addition, irrigation schedules were not reduced once the hot weather passed.
