9ENT BY: HP LA~ERJET 31~0~ B50281§102~ MAR-21-02 §:38AU; PASE 8/10 <br /> <br /> Redwood Shores Area, dated 22 January 2002. This recent study will be used as the basis for <br /> performing additional work under this task. The intent is to identify all facility requirements and <br /> cost components, develop an overall recycled water CIP, create a phased implementation plan, <br /> and perform an economic analysis cfa recycled water system that would serve the most cost- <br /> effective customers these three areas of Redwood City, and maximize the use of recycled water. <br /> <br /> Task 3.q - Refined Market Assessment <br /> Cons~ltant will refine the recycled water market assessment for the "Greater Bayfront" Area. <br /> Consultant will collect, review, evaluate and summarize specific irrigation and non-irrigation <br /> demand information through field reconnaissance *,ad using information provided by the City's <br /> Community Development Services Department for proposed development and re-development. <br /> A meeting will be conducted with the City's Community Development Services Depsat,~ent and <br /> the City's Enviromnental Consultant to collect and discuss development information. Existing <br /> and future recycled water customer locations and demands will be identified and summarized in <br /> tabular form and depicted using the City's Geographical Information System or existing aerial <br /> photography. Thc existing market assessment for Redwood Shores and Central Redwood City <br /> will be reused from the aforementioned Redwood Shores study, and a composite market <br /> assessment map will be created in GIS or using aerial photography, showing the relative size, <br /> customer identification number and location of customer demands in the three areas of Redwood <br /> City being addressed under this study. Specific meter connection locations will not be shown for <br /> customers in the Greater Bayfront and Central Redwood City areas, unless provided by the City. <br /> <br /> Subtask 3.2 - Treatment Evaluation <br /> The additional treatment facility requirements for producing recycled water to serve customers <br /> outside of the Redwood Shores area will be developed based on prior work, for the recycled <br /> water market identified under Subtask 3,1. Capital and operations and maintenance requirements <br /> will be developed for two disinfection options, hypochlorite and ultraviolot light (UV), and a <br /> map will be prepared showing the location and phasing of required treatment facilities. SBSA <br /> will be contacted to discuss new information regarding SBSA's investigation into the final <br /> feasibility of using ultraviolet light for disinfection. Available results of the UV investigation <br /> will be incorporated into the treatment evaluation. <br /> <br /> Subtask 3.3 - Distribution Evaluation <br /> The distribution system will be evaluated for up to thur alternatives, using the following step-by- <br /> step approach. <br /> <br /> . Identify an initial transmission and distribution pipeline system alignment in (}IS or on <br /> aerial photography, based on prior work and Subtask 3.1. Distribution pipelines and <br /> service laterals will be shown for connection of all proposed customers to transmission <br /> pipelines. <br /> <br /> · Meet with City staff to discuss pipeline alignment constraints, storage/pumping site <br /> possibilities, special pipeline crossing requirements, and opportunities to combine <br /> construction ct'recycled water pipelines with other planned City projects. <br /> <br /> Recycled Water Program Support Services 3 of 7 ~Jla/2002 <br /> 12:38 PM <br /> <br /> <br />
