20 <br /> 2-inch and 12-inch water lines From U.S. Highway 70 down <br /> Redman Road to south side of <br /> Southern Railroad <br /> Extending the 12-inch water main along U.S. 70 to the approximate center <br /> of the northern quadrant of the District would cost approximately $62,500. <br /> This cost includes 2,000 linear feet of 12-inch ductile iron water line at <br /> $25 per linear foot plus contingencies and engineering costs(25%). <br /> Another potential provider is the City of Mebane (Graham-Mebane Water <br /> System) through an existing 12-inch water main which terminates at the <br /> Pak-Lite plant on Washington Street south of the Southern Railroad 0.3 <br /> mile from Buckhorn Road. <br /> Sewage Disposal Orange County's Efland sewer system has an 8-inch <br /> gravity line on the north side of U.S. Highway 70 which terminates 400 <br /> feet west of Richmond Road. Any service west or south of that point <br /> would have to be pumped, and flows of up to 100,000 gallons per day <br /> (GPD) could be accommodated in that line. Plants with flows of greater <br /> than 100,000 GPD would have to pump farther to the east to a section of <br /> 12-inch gravity sewer line. <br /> The four intermittent streams in the northern quadrant flow south, <br /> underneath I-85 and converge in the southern quadrant of the EDD <br /> Sewer construction which will occur as the ETD develops should rely to <br /> the extent possible on gravity flow in order to minimize the number of <br /> pip stations and associated costs. A system which maximizes the use of <br /> gravity flow would include construction of gravity lines alone <br /> intermittent streams in the north quadrant. and underneath 1-85 to West <br /> Ten Road. A single pump station near the stream crossing at West Ten <br /> could then convey wastewater from the entire EDD to a=vi section of <br /> the Eflan_d sewer system <br /> Otherwise- several pip stations could be nece awry in the northern <br /> Quadrant of the EDD because the topggr=hy there generally ,ns <br /> 12e=ndicular to the gravity sewer on Highw y 70 <br /> Cost estimates for construction gravity system along the streams and a <br /> pup station at West Ten may be developed to determine potential <br /> funding scenarios. <br /> swien having 100,000 QRD twer-age aad 250,000 peak ge,Aege fiews to the pump swien weaid then be puolped by way of a- <br /> . <br />
