years as withdrawals increase from Corporation Lake. An additional supply of 2.5 mgd is available from Lake Orange located upstream on the Fno River. This reservoir is owned and controlled by Orange County. The County, however, has not assigned the supply from this reservoir to any specific area. , Hillsborough is interconnected with both the Orange-Alamance Water System and OWASA. Hillsborough can receive up to 0.7 mgd from the Orange-Alamance system through a 6 inch pipeline. As noted earlier they can supply up to 2.0 mgd to OWASA during dry periods. Water demand projections for the Town of Hillsborough system are shown in Bigure 2-19. The Figure indicates that the system's current water supply source will be adequate to meet the highest projected demand only through the year 1983. It will need an additional, supply of 1.2 mgd to meet projected needs through the year 2000. Orange-AlamanCe Water Systems Incorporated Orange-Alamance Water Systems (CAWS) is a nonprofit association formed in 1969. Its service area is along the U.S. 70 corridor west of Hillsborough through the Efland community and on into Alamance County. In Alamance County the system serves rural, areas around the Town of Mebane. About one-quarter of OAWS customers are in Orange County. OAWS gets its raw water from Corporation Lake, an impoundment on the Eno River just north of U.S. 70. This source has a safe yield of approx- imately 1.3 mgd. QAWS is currently serving about 4800 persons on 1600 metered connections. Based on records for 1979, the system pumped an average of 0.34 mgd. In an emergency situation, OAWS can pump 0.7 mgd of water to the Hills- borough system. The OAWS system is also interconnected with the Graham-Mebane water system. The Graham-Mebane system in turn is conn- ected to the Gity of Burlington's system. Projected water demand for the OAWS system is shown on Figure 2-20.The Figure shows that,even for the highest water demand curve, the OAWS sys- tem has adequate supply to meet water demand to and beyond the year 2000. Potential Water S .. Sources For Or :- County The water demand projections developed for the OWASA system show an imme- diate need in southern Orange County for an additional source of supply. While the two water suppliers in central Orange County have ad- equate supplies to meet near-term needs, in the long term they will have to find additional, sources of water to supply a growing population in Orange County. A number of potential Impoundment sites have been identified in struc- ture site studies carried out in the past. Because the physical charac- teristics which are necessary for a good reservoir site (sufficient stream 18
