sj 3-inch Water Line West side of Buckhorn Road from south side of Southern Railroad to I-85 2-inch and 12-inch water lines From U.S. Highway 70 down Redman Road to south side of Southern Railroad Extending the 12-inch water main along U.S. 70 to the approximate center of the northern quadrant of the District would cost approximately $62,500. This cost includes 2,000 linear feet of 12-inch ductile iron water line at $25 per linear foot plus contingencies and engineering costs (25%). Another potential provider is the City of Mebane (Graham-Mebane Water System) through an existing 12-inch water main which terminates at the Pak-Lite plant on Washington Street south of the Southern Railroad 0.3 mile from Buckhorn Road. Sewage Disposal Orange County's E11and sewer system has an 8-inch gravity line on the north side of U.S. Highway 70 which terminates 400 feet west of Richmond Road. Any service west or south of thai point would have to be pumped, and flows of up to 100,000 gallons per day (GPD)could be accommodated in that line. Plants with flows of greater than 100,000 GPD would have to pump farther to the east to a section of 12-inch gravity sewer line. The four intermittent streams in the northern quadrant flow south underneath_I-85 and converge in the southern quadrant of the EDD Sewer construction which will occur as the EDD develops should rely to the extent possible on gmyity flow in order to minimize the number of pump stations and associated costs by the use of gmyity lines along the intermittent streams in the north Quadrant and underneath I-85 to West Ten Road. A single pump station near the stream crossing at West Ten could then convey wastewater from the entire EDD to a gravity section_of the Eflaud sewer system. Otherwise.several_pump stations could be necessary in the northern quadrant of the EDD because the top.Q by there generally runs pe=jWicular to the gravity sewer on High=70. Cost estimates for constructing a grayiV system along the streams and a pump station at West Ten may be developed to determine potential funding scenarios. statien having 100,000 GPD avefage and 250,000 peak eapaei4ies.
