➢ Treatment Plant & Collection System Description:
The Moore County Water Pollution Control Plant (WPCP) is located at 1094 Addor
Road in Aberdeen, North Carolina and operates under Permit No. NC0037508. The
facility is currently permitted to treat 10 MGD. Flow entering the plant passes through
1 of 2 bar screens to the raw sewage influent pumps that transport the wastewater up to
the grit removal units. Treatment is accomplished by splitting the flow between 3 trains,
each consisting of a primary clarifier, 1st stage aeration basin, intermediate clarifier, 2nd
stage aeration basin and a final clarifier. All flow then passes through sand filtration
followed by UV disinfection. The treatment plant uses a biological treatment process to
remove pollutants in the wastewater that can potentially be harmful to the environment
and to the receiving stream. The facility uses anaerobic digestion to treat the sludge
removed from the wastewater treatment process. The method used to dry sludge is belt
filter press; the dried sludge is stored on -site then hauled to a landfill. These processes
are maintained by Operators certified by the State of North Carolina and are inspected
annually by the North Carolina Department of Environment Quality (NCDEQ).
Reports are submitted monthly to NCDEQ that contain the results of testing done on
the incoming raw wastewater and treated effluent discharged from the plant.
The treated water is discharged from the Plant into Aberdeen Creek in the Lumber
River Basin. The wastewater enters the Plant from an interceptor sewer, a collection
system that is made up of approximately 15 miles of gravity sewer lines that is capable
of handling 32 MGD. This interceptor sewer receives wastewater from the collection
systems of the following municipalities: Aberdeen, Carthage, Pinebluff, Pinehurst,
Southern Pines, and Vass. The WPCP facility also receives flow from Camp MacKall
and the Town of Hoffman via force mains that discharge directly into the WPCP raw
sewage pump station. As part of this interceptor system, there are 19 flow monitoring
stations that record flow information for bulk billing purposes to the municipalities.

Moore County Public Utilities (MCPU) is responsible for the Pinehurst Collection
system. All together the interceptor sewer and Pinehurst collection system consist of
28 miles of force mains, 207 miles of gravity lines, and 43 pumping stations.
