The study area boundaries will be as defined and presented in a GIS format. Key political jurisdictions will be defined including public and private utilities service areas . Subtask 5.2 — Identify Major Reclaimed Water Users . Within each proposed Reuse Service Area, identify all major users of reclaimed water, typically defined as customers using an average of 100, 000 gallons or more of reclaimed water per day will be identified and located on a map of the System. Also identify the location of any planned residential or commercial developments to be served initially by the reclaimed water system. Subtask 5.3 — Forecast Initial and Future Reclaimed Water Demand Projections. Prepare reclaimed water demand projections for each proposed Reuse Service Area in 5 - year increments over the next 20 years . Relate the number of potential reclaimed water customers and the potential reclaimed water demand to wastewater treatment capacity and the quantity of reclaimed water that will be available in each Reuse Service Area over that period. Subtask 5.4 — Develop Conceptual Design of Reclaimed Water System. For each Reuse Service Area, develop recommendations for wastewater reuse and develop a conceptual layout for a reclaimed water storage, transmission and distribution system. Depending on operational requirements and the locations of planned developments, the conceptual layouts may or may not include the existing transmission loop that supplies effluent disposal sites . The initial phases of reclaimed water system development will likely focus on the areas between the source (WWTF) and one or two major users in the Reuse Service Area. The conceptual designs will include planning level definition of the following: • Developments or geographical areas to be served initially with reclaimed water; • Availability of reclaimed water customers, reclaimed water demand, and potential revenues from the sale of reclaimed water; • Improvements at reclaimed water production facilities (WWTFs) that are required to produce a reliable supply of reclaimed water; • Approximate locations and sizes of reclaimed water storage tanks, pumping stations, and transmission mains required initially in each Reuse Service Area; • A planning level opinion of probable construction cost; and • A plan for phased construction over the next 10 years, taking into account developers ' timelines for having new reclaimed water customers connected to the County' s System. Simplified hydraulic models will be used to develop a conceptual layout and the approximate sizing of reclaimed water system components required for each Reuse Service Area. The models will be developed using GIS data available from Indian River S:\041077.003\IRC Reclaimed Water System Implementation PlanWttachment I .doc October 1 , 2005
