Ashland WWTP and Sewer System - Municipal Wastewater Treatment in Ashland, Ohio

The Ashland WWTP and Sewer System is a municipal wastewater treatment facility located in Ashland, Ohio, United States. It serves a population of about 21,249 residents in the city and surrounding Montgomery Township, Ashland County. The plant is situated inland, approximately 50 km from the nearest coast, and operates under the regulatory framework of the US Clean Water Act. As a facility serving a medium-sized agglomeration, the plant is expected to provide at least secondary treatment under National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. Plants of this scale typically employ biological treatment followed by disinfection to meet effluent limits for biochemical oxygen demand, total suspended solids, and other pollutants. The treated effluent is discharged to a receiving water body within the Lake Erie basin, ultimately draining into the Great Lakes system. The plant plays a key role in protecting downstream water quality, supporting aquatic life, and preventing nutrient pollution that could contribute to algal blooms in Lake Erie.

The Ashland WWTP discharges into a tributary of the Black Fork of the Mohican River, which flows into the Muskingum River and eventually reaches the Ohio River and Mississippi River system. The plant's effluent contributes to the water quality of these waterways, which support diverse aquatic ecosystems and are used for recreation and drinking water. The facility's nutrient removal performance is important for mitigating downstream eutrophication risks.
