Wastewater Plant Information
Marion
The Marion WWTP is located in the City of Marion and serves the City of Marion residents. The plant is permitted to treat 6.0 million gallons per day and discharge treated effluent to the Great Pee Dee River near Pee Dee.
The plant employs the Activated Sludge Oxidation Ditch process to maintain high quality effluent prior to discharge into its receiving stream.
The biological solids that are generated during the treatment process are treated to Class A standards through composting to provide the most beneficial reusable product. The composted material is utilized as crop fertilizer at several of the SCDHEC approved Authority farms.
