14 <br /> • significant upgrades to the existing wastewater collection system to handle the increased <br /> flow from this large area, <br /> • upgrades to the Mason Farm Wastewater Treatment Plant, and <br /> • operation and maintenance of the new infrastructure. <br /> The area north and west of the Gravity Sewer Boundary generally flows northward to Morgan <br /> Creek and may be serviceable by gravity. A small area near the intersection of Smith Level <br /> Road and US 15-501,while not flowing northward to Morgan Creek,appears to have adequate <br /> slope to reach a gravity system. The boundary for the University Lake watershed to the west, <br /> which also restricts extension of water and sewer service,follows closely with Smith Level <br /> Road. Planning to serve the area above the Gravity Sewer Boundary would require <br /> consideration of several factors,including the need and costs for. <br /> • new gravity sewer lines for the new development, <br /> • upgrades to the existing wastewater collection system to handle the increased flow, <br /> ■ long-range planning for upgrades to the Mason Farm Wastewater Treatment Plant,and <br /> • operation and maintenance of the new infrastructure. <br /> Rule of thumb cost estimates include$200 per foot for 8-inch sewer lines and$750,000- <br /> $1,000,000 for a typical wastewater pump station. <br /> Water <br /> Water can be provided within the area of interest. Planning to serve this area with water, <br /> however,would require consideration and analysis of several factors,including the need and <br /> costs for <br /> • new water distribution lines for the new development; <br /> • upgrades to the existing distribution system to handle the increased flow,including the <br /> possibility of a new elevated water storage tank and pump station to serve portions of <br /> the Chapel Hill transition zone; <br /> ■ long-range planning for upgrades to the Jones Ferry Road Water Treatment Plant;and <br /> • operation and maintenance of the new infrastructure. <br /> Rule of thumb cost estimates include$200 per foot for 8-inch water lines and$1,500,000 - <br /> $2,000,000 for an elevated storage tank and pump station, should modeling indicate a new tank <br /> was needed. <br /> I hope you find this information helpful.
