Treatment Plant & Collection System Description:
The Moore County Water Pollution Control Plant is located at 1094 Addor Road
in Aberdeen, North Carolina and operates under Permit No. �C003 075 The
facility is designed to treat 6.7 million gallons a day (MGD) and consists of a raw
sewage pump station, a mechanical bar screen, 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.
Two forms of sludge drying are being used. The first is mobile containment
dewatering which is hauled to a facility and composted. The second method used
to dry sludge is sand drying beds; once this sludge is dry it is hauled to a lined
landfill. 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. This facility has been in
compliance with all permit limits set by the state and has passed with a
satisfactory rating on this year's inspection. The treated water that is discharged
from the facility goes 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
1

directly into the facility's pump station. As part of this collection system, there
are 13 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 over 20 miles of force mains, 150 miles of
gravity lines, and 38 pumping stations.
Performance
July 2006
July 24, 2006 The Moore County Water Pollution Control Plant failed the
multiple dilution toxicity test for the month of July 2006 with a result of 14.5%.
