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

The Jamestown WWTP and Sewer System is a municipal wastewater treatment facility located in Jamestown, Ohio, a small village in Greene County. Serving a population of around 4,400, the plant is part of the community's essential infrastructure for managing domestic wastewater. As a small-scale facility, it operates under the regulatory framework of the U.S. Clean Water Act, administered by the Ohio Environmental Protection Agency (Ohio EPA). Plants of this size in Ohio typically employ secondary treatment or advanced technologies to meet National Pollutant Discharge Elimination System (NPDES) permit requirements. The facility is subject to state and federal standards for effluent quality, ensuring protection of receiving waters. The plant's treated effluent is discharged into local streams that flow into the Great Miami River, a major tributary of the Ohio River. The Great Miami River basin supports diverse aquatic life and provides recreational and drinking water resources. The plant plays a key role in maintaining water quality in this ecologically important watershed.

The Jamestown WWTP discharges into small tributaries of the Great Miami River, which flows southwest to join the Ohio River near Cincinnati. The Ohio River then drains into the Mississippi River and ultimately the Gulf of Mexico. The Great Miami River basin is ecologically significant, supporting species such as smallmouth bass and freshwater mussels. Protecting this watershed from nutrient pollution and pathogens is critical for downstream ecosystems and human uses.
