The Aberdeen Wastewater Treatment Plant located a mile south of Melgaard road, was constructed in 1987 and upgraded starting in 2006.

The Wastewater Plant reclaims, on average, four million gallons of wastewater per day.

Treatment of Wastewater
The Wastewater Treatment Plant removes oxygen demanding pollutants, solids, and ammonia from the wastewater using both mechanical and biological means.

The treated water (called effluent) is then discharged into Moccasin Creek. This is regulated by the issuance of a Surface Water Discharge permit.
