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 />P38 <br />
