Clarksville WWTP and Sewer System - Advanced Wastewater Treatment in Ohio

Clarksville WWTP and Sewer System is a municipal wastewater treatment facility located in Clarksville, Ohio, United States. Serving a small population of 497, the plant provides advanced treatment to protect local water quality. The facility is situated in Clinton County, within the rural landscape of southwestern Ohio. The plant operates with advanced treatment processes, exceeding the secondary treatment standard required by the US Clean Water Act for municipal facilities. With a designed capacity of 340.69 megaliters and an annual discharge volume of 227.13 megaliters, the plant manages wastewater from the local community effectively. Under the National Pollutant Discharge Elimination System (NPDES), the plant is expected to meet stringent effluent limits to safeguard receiving waters. The treated effluent is discharged into a local waterway that eventually drains into the Ohio River basin. The plant's advanced treatment helps reduce nutrient loading and protect downstream aquatic ecosystems, including the Ohio River and its tributaries, which support diverse fish and wildlife populations.

The plant discharges into a tributary of the Little Miami River, which flows into the Ohio River and ultimately the Mississippi River. The Little Miami River is a designated State Scenic River, supporting diverse aquatic life and providing habitat for species such as smallmouth bass and freshwater mussels. The advanced treatment at this plant helps maintain water quality in this ecologically sensitive watershed.
