Description of Collection System or Treatment Process:
DENR WATER QUALITY
DWQ
The collection system consists of five lift stations located throughout the Town and 120 low
pressure grinder pumps at customer's homes. The main lift station that takes the wastewater to
the treatment plant is located on Clinton Street behind Two Dogs Pizza. This lift station is fed by
a gravity sewer and has an automatic 60 KW generator for backup power in the event of power
failure. A lift station is located at McDonald's on 50/55 highway. A lift station is located
approximately one quarter of a mile outside the Town limits on 50/55 highway. Another lift
station is located at the trailer park on Mt Olive highway. A lift station is located at Hobbton
School on Clinton Highway and pumps directly to the treatment plant. The treatment plant is
located on Pork Chop Hill Road off Bryan Road. It consists of abar screen, flow equalization
basin, an oxidation ditch/clarifier, a tertiary sand filter, aerobic digester, and flow
monitoring/disinfection station. Ultraviolet light is usedto disinfect the water before being
discharged into Beaver Dam Swamp and ultimately into Coharie Creek. A generator is located at
the plant for power supply during power outages. This generator comes on automatically during
power failure.
All sludge generated at the plant enters an aerobic digester. Upon proper digestion, the
sludge is then applied on a 7.4 acre permitted site (Permit#WQ0010470), adjacent to the
treatment plant. Approximately 250,000 gallons of sludge are applied each year.
