Fairfield Co Pleasant Run WRF - Projected Wastewater Treatment Plant in Fairfield County, Ohio

Fairfield Co Pleasant Run WRF is a planned wastewater treatment facility located in Pleasant Township, Fairfield County, Ohio. The plant is designed to serve a population of 2,655, positioning it as a small-scale municipal treatment facility within the state's wastewater infrastructure. As a projected facility, the plant will be subject to the US Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting requirements. For small agglomerations in Ohio, typical treatment includes secondary treatment to meet effluent limits for biochemical oxygen demand and total suspended solids, with possible nutrient controls depending on the receiving water body. The plant's discharge will ultimately drain into the Ohio River basin, which flows into the Mississippi River and then to the Gulf of Mexico. The facility's location in inland Ohio means its effluent will contribute to the watershed that supports diverse aquatic life and serves as a major migratory corridor for birds and fish.

The plant's discharge will enter local streams that feed into the Ohio River watershed, part of the larger Mississippi River basin. This inland system supports diverse aquatic species and provides critical habitat for migratory birds and fish. The Ohio River eventually flows into the Mississippi River and then to the Gulf of Mexico, making nutrient management important to prevent downstream hypoxia.
