Fairfield Co Pleasant Lea WWTP - Advanced Wastewater Treatment in Fairfield County, Ohio

Fairfield Co Pleasant Lea WWTP is an advanced wastewater treatment facility located in Pleasant Township, Fairfield County, Ohio. The plant serves a small population of 282 residents, reflecting its role in a rural or suburban community. Its location in the interior of Ohio places it within the broader context of the state's water management infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 151.42 units and an actual discharge volume of 75.71 units, the facility operates well below its capacity, indicating room for future growth or seasonal variability. As a US plant, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency, ensuring compliance with federal water quality standards. The treated effluent from the plant is discharged into local waterways that ultimately drain into the Ohio River basin. The Ohio River is a major tributary of the Mississippi River, supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps protect downstream water quality, particularly in sensitive watersheds that feed into larger river systems.

The plant discharges into local streams within the Ohio River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River basin supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. Advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing algal blooms and maintaining ecological balance in downstream waters.
