Jefferson WWTP and Sewer System - Ohio Wastewater Treatment Plant

The Jefferson WWTP and Sewer System is a municipal wastewater treatment facility located in Jefferson, Ashtabula County, Ohio. It serves a population of about 3,572 residents, providing essential sanitation services to this rural community in the northeastern part of the state. As a small-scale treatment plant in the United States, it operates under the regulatory framework of the Clean Water Act, administered by the Ohio Environmental Protection Agency. Facilities of this size are typically required to meet secondary treatment standards, ensuring that effluent quality protects local water bodies. The plant's treated effluent is discharged into a local waterway that ultimately drains into the Lake Erie basin. Lake Erie is a vital freshwater resource that supports diverse aquatic life and provides drinking water for millions. The plant plays a key role in protecting this sensitive ecosystem from nutrient pollution and other contaminants.

The plant discharges into a tributary of the Grand River, which flows northward into Lake Erie. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting important fisheries and recreational activities. The watershed is predominantly agricultural and rural, making nutrient management a key concern for downstream water quality.
