Ironton WWTP and Sewer System - Ohio Wastewater Treatment Plant

The Ironton WWTP and Sewer System is a municipal wastewater treatment facility located in Ironton, Lawrence County, Ohio. Serving a population of around 12,000, the plant is part of the city's essential infrastructure for managing domestic wastewater from the community. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. The plant's treated effluent is discharged into the Ohio River watershed, which flows into the Mississippi River and ultimately the Gulf of Mexico. The Ohio River supports diverse aquatic life and provides drinking water for millions downstream, making effective wastewater treatment critical for regional environmental health.

The plant discharges into the Ohio River basin, a major tributary of the Mississippi River system. The Ohio River supports a variety of fish and wildlife species and is an important migratory corridor for birds. Downstream, the river flows into the Mississippi and reaches the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones. Effective treatment at this plant helps reduce nutrient and pollutant loads to the river.
