F <br />4 <br />to create a relatively low pressure zone which would provide <br />adequate fire protection by increasing the water flow <br />capacity in the area along Churton St north of Mayo St. <br />Hillsborough proposes to use the segment between Oakdale <br />Drive and Davis Road to provide for future development in the <br />southern Hillsborough service area. The segment of line <br />between Oakdale Dr and I -40 would eventually be to create a <br />loop in the Town's future water system. This loop would <br />connect -the Old 86 line segment to an elevated water storage <br />tank which would be located in the area between old and new <br />NC 86. This elevated tank would also be connected to the <br />existing 12 inch water main at or near the intersection of NC <br />86 and New Hope Church Road. The remaining section of the <br />purchased 16 inch segment between I -40 and Davis Road could <br />be used to serve future development, if any. around the I -40 <br />and Old NC 86 interchange. <br />The proposal by Hillsborough to purchase the segment of line <br />described above reflects sound engineering judgement in terms <br />of addressing the long and short term needs of the Town of <br />Hillsborough. If Hillsborough does not obtain the segment of <br />the existing OWASA main, it will have to install at least a <br />12 inch line along the same route as the existing line to <br />fulfill its long term plans for water service areas, elevated <br />storage tanks and looped system of mains. The construction <br />costs for 13.000 feet of 12 inch main from Davis Drive to <br />Mayo Street would be approximately $450.000 in 1991 dollars. <br />There would probably not be any significant near term <br />financial saving for Hillsborough in purchasing the existing <br />sixteen inch main as opposed to constructing a new twelve <br />inch line. In addition to the cost of purchasing the <br />existing main from OWASA, construction of a new OWASA pump <br />station in the vicinity of Davis Road would be required. The <br />existing OWASA pump station at Calvander would be unable to <br />pump water from OWASA into Hillsborough's high pressure zone <br />without replacing its existing pumps. As OWASA plans to use <br />the Calvander pumping station to create a high pressure zone <br />of its. own, it would not be interested in changing the pumps <br />in the Calvander pumping station, thus the need for the new <br />pump station at pavis Road. The total cost of the <br />construction of the Davis Road pump station. moving the water <br />meter from the Exchange Club to Davis Road, and the purchase <br />of just the 13.000 foot segment of the 16 inch main from Mayo <br />Street to Davis Road (at the price per foot offered by <br />Hillsborough) would be in the $500,000 to $600,000 range. <br />This cost is comparable to the cost of $500,000 for the <br />construction of 13,000 feet of twelve inch main, engineering <br />and contingencies. - <br />There are several other advantages to the Town with the <br />purchase of the existing line. however. The Town would not <br />have to find a way to construct a new main along Churton <br />Street and under I -85. Considering the already crowded <br />
