Infrastructure The Orange-Alamance system can be basically described as consisting of: 1) its original 1.0 mgd water treatment plant, which is located at the northwest quadrant of the intersection of the Eno River and US Hwy 70 west of Hillsborough and east of Efland; 2) a 12" diameter water main trunk line extending west along Hwy 70 from the plant to a point just east of Mebane city limit, then north and west through and across the northern end of Mebane, then south along the west side of Mebane and crossing the interstate at Trollinger Road to NC 119, then continuing south along NC 119 through Hawfields and across NC 54 to Swepsanville; 3) one 300,000 gallon elevated water tank in Orange County (on Hwy 70 adjacent to the Hancor Plant) and one 300,000 gallon and two 100,000 elevated water tanks in Alamance County (US 70 west of Mebane; NC 119 and Swepsonville); and 4) a number of smaller diameter water mains and lines, from 2" to 8" in diameter serving azeas in both Orange and Alamance Counties that are outlying from the route of the primary 12" diameter trunk main. Furthermore, Orange Alamance awns and operates or will operate two ground water wells, each with a rated capacity significantly in excess of 100,000 gpd, one located on the grounds of the treatment plant in Orange County and one at the elevated water tank on NC 119 in Alamance County (the Alamance well has not yet been put in service but will be very soon). Water from the well at the treatment plant is currently run through the treatment plant before it enters the distribution system. Water from the well at the elevated water tank will be chlorinated and discharged directly into the distribution system. Orange Alamance also owns an approximately 30 acre site on NC 54 in Alamance County just east of Swepsonville where Haw Creek flows under NC 54. The original plan for this site was as a location for a raw water intake on Haw Creek and a water treatment plant. However, during the state's drinking water watershed classification process during the early and mid 1990's, Orange- Alamance (at the behest of Mebane and Graham) officially abandoned this property as a raw water intake site and petitioned the Environmental Management Commission to declassify the Haw Creek watershed as a water supply watershed. In Orange-Alamance's Orange County service azea (shown on the attached map), most of the customers lie in the US Hwy 70 corridor bounded by I-85 on the south and Lebanon Road on the north. However, there are about 20 customers in the area near the intersection of Mount Willing Road and West Ten Road south of I-8S and perhaps 40 customers on the north side of Lebanon Road in areas neaz the intersections of Lebanon Raad and Frazer Road and Lebanon Raad and Brookhallow Road. Customers in both Orange and Alamance Counties that are not adjacent to the 12" main are served from the network of smaller diameter, often dead-end, mains. While the Orange-Alamance. distribution network does contain f re hydrants (primarily along the trunk main), the system is not generally designed to provide fire protection. It certainly could oat be expected to meet fire protection standards far water pressure or flow in azeas not adjacent to the 12" trunk line. Although there aze oat widespread or frequent problems ar complaints with low water flow or low water pressure on the Orange-Alamance distribution system, customers located at the ends of long segments of small diameter water mains may occasionally suffer from conditions of low flow or pressure. This would be particulazly true during periods of high demand at the upstream portions (nearest the trunk mains) of small diameter water lines. 4
