Baird, County Administrator <br />Vincent Burke, P.E., Director of Utility Services <br />Arjuna Weragoda, P.E., Capital Projects Manager AW <br />Subject: Water Distribution Model -Work Order No.7 <br />?n% <br />D ESCRIPTIONS AND CONDITIONS: <br />Indian River County Department of Utility Services (IRCDUS) needs to update the existing water <br />system hydraulic model to reflect current GIS (Geographical Information System) data and better <br />represent the current system configuration. The existing water system model is in an older version of <br />WaterCAD format, and is outdated and therefore does not reflect the current system configuration. <br />System water demand is the quantity of water that the treatment plants must produce in order to meet all <br />water needs in the community. Water demand includes water delivered to the system to meet the <br />needs of consumers, water supply for fire fighting and system flushing, and water required to properly <br />operate the treatment facilities. In order to accurately evaluate the existing distribution system <br />within the County and determine its strengths and weaknesses and predict when and where <br />additional pipeline, storage and pump station capacity is required, a good hydraulic model must be in- <br />place. Once a hydraulic model has been established for the entire County, the model can address <br />things such as hydraulic and water quality problems, improve pressures and fire flow, and make sure <br />the system can meet peak hour demands. <br />ANALYSIS: <br />Staff requested that Kimley-Horn and Associates prepare a proposal to evaluate modeling the <br />existing water distribution system. The scope of the evaluation is more specifically described in the <br />attached Exhibit 1 under Work Order No.7. <br />Kimley-Horn and Associates has submitted Work Order No. 7 to evaluate and prepare a hydraulic <br />model of the existing distribution system. On November 15th, 2011, the Indian River County Board <br />of County Commissioners approved the Continuing Contract Agreement for Professional Services <br />with Kimley-Horn and Associates. The total negotiated cost for the hydraulic analysis is a lump sum <br />amount of $ 24,700.00. A basic hydraulic model network of the water system in WaterCAD v8 <br />format with one (1) topology configuration being TODAY conditions assuming maximum daily flows <br />(MDF) and average daily flow (ADF) will be provided. Also included in the deliverables will be an <br />output file containing system pressures flows, and fire hydrant flow test results. <br />133 <br />
