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 basins, intermediate clarifier,
2nd stage aeration basins 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 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 all the results of testing done on
the incoming raw wastewater and treated water discharged from the plant.
The treated water is discharged from the facility into Aberdeen Creek in the Lumber
River Basin. The wastewater enters the facility 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 system 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
via force main that discharges 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 also responsible for the Pinehurst Collection
system. All together the interceptor and Pinehurst collection system consist of 28 miles
of force mains,207 miles of gravity lines, and 43 pumping stations.
