WASTEWATER TREATMENT PLANT
2005 Old Chappell Hill Road
Bobby Keene, Jr., Superintendent
The Wastewater Treatment Plant is responsible for the treatment of wastewater received from the wastewater collection system for discharge into local creeks. The wastewater must be treated to meet strict federal and state limits before being discharged.
The wastewater is received by gravity flow to the treatment plant. Once at the plant, the wastewater enters the main lift station and is pumped in the head works where (2) mechanical bar screens remove large objects from the wastewater. The wastewater then flows through a grit chamber where sand and grit is removed. After this process, the wastewater flows into a diverter box where the flow is divided between the new aeration basin and the old aeration basin. The wastewater is then aerated for additional treatment with bacteria and other organisms which help breakdown the solids. Once this is done, the wastewater enters the clarifiers where the solids settle out. The clear supernatant then flows to the chlorine contact chamber where it is treated with Chlorine, followed by de-chlorination with Sulphur Dioxide in order to discharge into Hog Branch Creek. Wastewater Clarifier
The wastewater must be treated to meet strict federal and state limits before being discharged. The remaining solids from the bottom of the clarifiers are pumped into the 4 large digesters which also help break down the solids by final aeration, organisms and bacteria. The remaining solids are then pumped to the belt press and treated as Class "A" biosolids which are then sold to local farmers and ranchers as a soil enhancer.
Inlet Lift Station
The Wastewater Treatment Plant has the capacity to treat up to 3.55 million gallons per day.
