Oberlin WWTP and Sewer System - Lorain County, Ohio Wastewater Treatment

The Oberlin WWTP and Sewer System is a municipal wastewater treatment facility located in Lorain County, Ohio, serving the community of Oberlin and surrounding areas. With a population served of about 8,195, the plant is classified as a small to medium agglomeration under U.S. regulatory frameworks. The facility is situated inland, approximately 50 kilometers from the Lake Erie coast, and its operations are subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting. As a plant serving fewer than 10,000 people, typical treatment expectations under the Clean Water Act include secondary treatment as a minimum standard. The designed capacity of 1.00 million gallons per day provides adequate capacity for the current service population. The plant's treatment process and operational status are consistent with standard municipal practices for facilities of this scale in Ohio. The treated effluent from the Oberlin WWTP ultimately discharges into the Lake Erie watershed, which is part of the Great Lakes Basin. Lake Erie is a critical freshwater resource supporting diverse aquatic life, recreational activities, and municipal water supplies. The plant's operations contribute to protecting the water quality of local streams and the downstream lake environment from nutrient pollution and pathogens.

The Oberlin WWTP discharges into the Lake Erie watershed, which drains into Lake Erie, the shallowest and most biologically productive of the Great Lakes. The lake supports a diverse ecosystem including fish species such as walleye and yellow perch, and is a vital resource for drinking water and recreation. The plant's location in an agricultural and urban area means its effluent management is important for controlling nutrient inputs that can contribute to algal blooms in the lake.
