Mr. L Harding Hughes, Jr. <br />January 14, 1987 <br />Page 3 <br />r t� <br />J <br />average out of a total pump capacity of 98,400 GPD average. Actual pump capacity <br />totals 246,000 GPD before applying a 2.5 peaking factor. Excess capacity of 14,725 <br />GPD average exists at this station, again allowing for the additional 10,500 GPD <br />average provided by the school. In any event, the 3 -inch force mains in the system are <br />capable of handling the additional influx as evidenced by pump tests performed at both <br />Woodsedge and Wildwood. <br />Preliminary design of the necessary facilities to transport sewage to the <br />Woodsedge pump station for further pumping to the waste treatment plant consists of <br />8,500 feet of 4 -inch PVC force main and an above ground duplex centrifugal pump <br />station. The new pump station must be located at the rear of the proposed site so that <br />discharge from the school can flow by gravity to the pump. The 4 -inch force main will <br />be routed from the pump station across school property to NC 86, which it will parallel <br />to the entrance of the Woodsedge development. From that point, the line will travel <br />down the Woodsedge access road where it will empty into the existing pump station. <br />The total cost for supplying sewer service to the school is estimated to be $138,050, <br />which includes $19,400 as a perpetual maintenance fee. A breakdown of the unit prices <br />used to develop this estimate is given in Table 3. <br />Attached to this report are general location maps of the proposed improvements <br />for both water and sewer extensions. Be aware that the locations of the proposed lines <br />are approximate and may be slightly altered pending final design. <br />If I can be of any further assistance, please feel free to let me know. <br />WDCIbc <br />Attachments <br />Sincerely, <br />David Cain <br />31 <br />rY �� <br />v � <br />
