Wastewater Treatment

Columbus City Utilities is proud of its new wastewater treatment facility.

The new treatment plant utilizes the most recent technology including a headworks with fine screening, grit removal, two new oxidation ditches, four final clarifiers, a return activated sludge (RAS) pumping station, UV effluent disinfection, a Cannibal Sludge Reduction Process ™, aerobic solids handling tanks, centrifuge biosolids dewatering, emergency power, odor control, and an administration and maintenance building.

The design includes provisions for expansion and potential nutrient removal process that may be needed to meet future effluent treatment requirements.

The plant was built with low interest loans from the State Revolving Fund plus $4m grant from the American Recovery and Revitalization Act.
