Coal Grove WWTP and Sewer System - Secondary Treatment Plant in Ohio

The Coal Grove WWTP and Sewer System is a municipal wastewater treatment facility located in Coal Grove, Lawrence County, Ohio. Serving a population of approximately 2,047, the plant is part of the region's infrastructure for managing domestic wastewater. The facility operates under the U.S. Clean Water Act, which requires secondary treatment for municipal plants discharging to surface waters. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 984.20 million gallons per year and an actual discharge volume of 757.08 million gallons per year, the plant operates below its capacity. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Ohio Environmental Protection Agency. The treated effluent is discharged into the Ohio River watershed, which flows into the Mississippi River and ultimately the Gulf of Mexico. The plant plays a key role in protecting local water quality and the downstream aquatic ecosystem, including the diverse fish and wildlife habitats supported by the Ohio River.

The plant discharges into the Ohio River basin, which drains into the Mississippi River and the Gulf of Mexico. The Ohio River supports a variety of aquatic life, including fish species such as bass and catfish, and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this ecologically significant river system.
