Jeromesville WWTP and Sewer System - Advanced Wastewater Treatment in Ohio

Jeromesville WWTP and Sewer System is a municipal wastewater treatment facility located in Jeromesville, Ohio, within Ashland County. Serving a small population of 478 residents, the plant is part of the local infrastructure managed by the village. The facility operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges into surface waters. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With an annual discharge volume of 189.27 megaliters and a designed capacity of 249.84 megaliters, the facility operates below its maximum capacity, indicating room for future growth. The treatment level meets or exceeds typical requirements for small communities in Ohio, which often mandate secondary treatment as a minimum. The treated effluent is discharged into a local waterway that ultimately drains into the Lake Erie basin via the Ohio River and Great Lakes system. This watershed supports diverse aquatic life and provides drinking water for millions downstream. The plant's advanced treatment helps protect water quality in this ecologically significant region, which is part of the larger Mississippi River drainage basin.

The plant discharges into a tributary of the Mohican River, which flows into the Walhonding River, then the Muskingum River, and eventually the Ohio River. The Ohio River is a major tributary of the Mississippi River, which empties into the Gulf of Mexico. This watershed supports diverse aquatic ecosystems, including fish species such as smallmouth bass and walleye, and provides habitat for migratory birds along the Mississippi Flyway.
