EXHIBIT#A <br /> Work Order Number 13 <br /> Roseland Elevated Tank Conversion <br /> to <br /> Repump Station <br /> PROJECT UNDERSTANDING <br /> Indian River County Utilities(IRCU)owns and operates the Roseland 750,000 gallon elevated <br /> storage tank, which is a steel hydro-pillar type that has a common inlet/outlet pipe that allows <br /> distribution water to fill and drain the tank,depending on system demands. Currently, an altitude <br /> valve controls the filling of the tank,but does not have the ability to drain and charge the <br /> surrounding water distribution system, since the tank operating level is much lower than normal <br /> system pressures. <br /> Several evaluations were conducted, one by Neel- Shaffer in 2007, and the latest recently by <br /> Kimley-Horn and Associates,Inc. in 2015,to determine the most cost effective method of <br /> correcting the elevation shortfall and optimize use of the elevated tank. The options which were <br /> considered were raising the tank,constructing a taller one adjacent to the existing one, or <br /> converting the existing tank to an elevated storage and repump facility. The last option of <br /> converting the tank to a storage and repump station that provides remote storage and repumping <br /> to the North Roseland service area is recommended. This allows the utilities the ability to <br /> maintain and optimize use of an existing asset and address future fire flow requirements for this <br /> area. The water distribution system hydraulic model,updated in July 2014,identified this area as <br /> an area having low pressures during peak demands and having difficulty meeting fire flow <br /> demands. <br /> Modification of the elevated storage tank to include repumping facilities will require <br /> modifications to the inlet and outlet piping configuration,requiring a new separate fill line to the <br /> storage tank. It is assumed that a new 12/16-inch water line, approximately 500 ft long will be <br /> required base on the current distribution piping model and GIS information. <br /> Based on the following assumptions and the scope of the project described herein,an opinion of <br /> probable construction costs are estimated to be$950,000. <br /> The following is a list of assumptions that the Consultant has made in the preparation of the Task <br /> Order. <br /> 1. A new separate waterline to act as a fill or outlet pipe will be needed to separate the <br /> pressure zones for a repump and storage facility. The length is assumed to be <br /> approximately 500 ft, and be a 12-inch or 16-inch waterline. <br />
