The water distribution system roughly covers the entire county with the exception of the northeastern portion. The distribution system consists of approximately 2,266 miles of water mains (July 2014). Staff maintains the water distribution system including mains, valves, hydrants, and connections. Staff also installs water connections at the request of customers in addition to managing the backflow prevention program.
This area provides wastewater collection to residential, commercial, and industrial customers. The sewer system serves approximately 64% of the occupied dwellings/businesses within the county. The wastewater collection system consists of approximately 1,781 miles of sewer mains (July 2014). The Construction & Maintenance staff maintain the collection system including the mains, manholes, sewer connections, and force mains. The staff also installs sewer connections at the request of the customers.
Overflow Reduction Efforts
Since the passage of the North Carolina Clean Water Act in 1999, the total volume of annual Sanitary Sewer Overflows (SSOs) has been tracked against the baseline year of FY99. For FY14, the total volume of sewer overflows represents a 92.6 percent decrease from the volume reported for the baseline year. There were a total of 82 sewer overflows during FY14, a 27 percent decrease compared with 111 overflows reported in FY13. This decrease in SSOs is directly related to proactive measures our field maintenance staff and Capital Project Engineers have executed.
The accumulation of fats, oils, and grease in sewer lines can cause blockages in the collection system. Of the 82 sanitary sewer overflows in the collection system during FY14, 26 were attributed to grease accumulation. This is the largest reduction in grease-caused overflows over previous years and reflects the continued effectiveness of the Grease Interceptor Ordinance (in place since 2003) and public education efforts. As a result of these efforts, a "Can the Grease" campaign was launched. This campaign included a brochure and associated educational materials. This information is routinely provided to the public at functions throughout the year. The reduction also reflects the proactive approach to cleaning sewer main lines and the publicly maintained portion of sewer connections. Sewer-line maintenance also prevents overflows due to the intrusion of tree roots and debris, which are the other major contributors to line blockages.

Reads and maintains all residential and commercial water meters in the system. Staff services and changes water meters, and performs cut-ons and cut-offs at the request of the customer and/or the Billing Office. The Meter Shop ensures that meters work effectively and are read properly in order that water consumption is accounted for and billed accurately. Maintenance includes replacing meters ranging from 3/4” to 2” and rebuilding meters.
Assists in maintaining water quality by flushing specified areas of the system, overseeing the Cross-Connection Control program which includes the testing and rebuilding the backflow assemblies as well as performing inspections of large meter (3"+) and fire service (private hydrant and sprinkler systems) connections through our "B" permitting process.
Cross-Connection Control Standards
For Backflow Preventers & Large Water Connections
Cross-Connection Control is the prevention of connections between a potable water supply and any source that can result in a health hazard contamination. The Technical Services section provides expert consultant services for: installation of backflow prevention devices for industrial, commercial, and residential applications of domestic, fire protection, and irrigation systems. Water connections are assessed for the degree of hazard they present, backflow preventer requirements are determined, and installations are inspected, tested, and maintained by state-certified technicians. The Cross-Connection Control standards for backflow preventers and large water connections serve as a technical reference for installation and material requirements.
