Coalton WWTP and Sewer System - Advanced Wastewater Treatment in Coalton, Ohio

Coalton WWTP and Sewer System is a municipal wastewater treatment facility located in Coalton, Ohio, United States. Serving a population of 545, the plant provides advanced treatment to protect public health and the environment in this small community within Jackson County. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. With advanced treatment, the facility exceeds the secondary treatment standard typically mandated for plants of this size, ensuring high-quality effluent. The designed capacity is 378.54 megaliters, with an actual discharge volume of 302.83 megaliters. The treated effluent is discharged into local streams that drain into the Scioto River watershed, ultimately reaching the Ohio River and then the Mississippi River. This contributes to the ecological health of the region's aquatic habitats, supporting diverse fish and wildlife populations.

The plant's discharge enters small tributaries within the Scioto River basin, which flows into the Ohio River and eventually the Mississippi River. This watershed supports diverse aquatic life, including several fish species and migratory birds. The advanced treatment helps maintain water quality in this inland system, reducing nutrient loading and protecting downstream ecosystems.
