The Moore County Water Pollution Control Plant is located at 1094 Addor Road in
Aberdeen, North Carolina and operates under Permit No: NC0037508. The facility is
designed to treat 6.7 million gallons a day (MGD) and consists of a raw sewage pump
station, two mechanical bar screens, grit removal system, two primary clarifiers, two
intermediate clarifiers, two final clarifiers, two aeration tanks, two digesters, and a
chlorination/dechlorination system.. 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 and treatment process. The method used to dry
sludge is sand drying beds; once this sludge is dry it is hauled to a composting facility.
These processes are maintained by operators certified by the state of North Carolina
and are inspected yearly by the North Carolina Division of Environment and Natural
Resources (NCDENR). Reports are submitted monthly to the state 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 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 is tied into the collection systems of the
following municipalities: Aberdeen, Carthage, Pinebluff, Pinehurst, and Southern
Pines. The facility also receives flow from Camp MacKall through a line that feeds
directly into the facility's pump station. As part of this collection, system, there are 14
monitoring stations that record flow information and two pumping stations that help lift
the wastewater to the gravity lines. Moore County is the owner of the wastewater plant
and collection system. It is also responsible for the Pinehurst Collection system that
consists of 16.4 miles of force mains, 198 miles of gravity lines, and 42 pumping
stations.
