Task 1: Project Initiation end Data Collection We will review data and information collected for the 1997 Water Supply and Distribution plan and supplement that data with information and data for facilities constructed since the 1997 Plan publication. Additionally, we will meet with Centervllle staff to get Input on any changes, modifications, or Improvements that they would like to see in the water system. Talk 2: Water Usage Review and Projections , We will review the City's water use dala collected since the 1997 Plan (maximum day, average day. I and monthly totals). This data will be used to establish existing and estimate future water use patterns within the City. We will establish water use at points throughout the City based on the updated land use plan. Design average day and maximum day water demands will be established for the yeal"!-g020 and the ultimate build out of the City. Maximum Fire flow requirements will be reviewad based on Insurance Services Office and City requirements. We will meel with the City to review the projected water demands and ~re flow requirements. Task 3: Wellfleld Review We will review the wellfiald to detenl1ine that It meets the needs of the City's ultimate water demand. This analysis will consist of estimating the number of additional wells required (based on capacity of I existing wells), and estimating the location of future wells (based on aveilable data). Task 4: Water Treatment Evaluation We will review the existing well water quality with respect to current and proposed drinking water standards, This evaluation wIll Include both public health concerns and aesthetic issues, such as taste, odors, and "red" or 'black" water complaints. j I Task 5: Hydraulic Modeling I The eXisting hydraulic model of the Centerville Water System will be upgraded to a WaterGAD I medel. WaterCAD is a powerfUl analytical tool that operates in a totally integrated AutoCAO and GIS1' environment. The computer model can be ...Iewed with City base maps, iand use maps. or Integrated into the City GIS system. By simulating operation of the water system, the computer model: I i I I i I , 01 Reveals system problems, 01 Predicts the effects of alternative solutions, and .; Predicts the effeclll of system expenslons. Pipes constrl./cted since the 1997 plan will be added to the model. The model will be used to size future trunk water mains to serve development as well as to determine the size and location of additIonal water storage. T.sk 6: Capital Improvement Plan A wllter utility must have a sound basis for planning the expansion of Its water system. This is ' especially true now, with Increasing regulatlons regarding property acquisition, publiC notification and construction. A sound Capital Improvement Plan (OIP) will enable Centervllle to ha...e the required I facilities in-place by the time they are needed.
