Junction City WWTP and Sewer System - Ohio Wastewater Treatment Plant

Junction City WWTP and Sewer System is a municipal wastewater treatment facility located in Junction City, Ohio, United States. Serving a population of 818, the plant is a small-scale operation that manages the community's wastewater needs within Perry County. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 378.54 cubic meters per day and an average discharge volume of 174.13 cubic meters per day, the facility operates well within its capacity. Under the U.S. Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency, ensuring compliance with effluent limits. The treated effluent is discharged into local streams that drain into the Muskingum River watershed, ultimately reaching the Ohio River and the Gulf of Mexico. This small plant plays a crucial role in protecting downstream water quality and aquatic habitats in the region.

The plant discharges into tributaries of the Muskingum River, which flows into the Ohio River and then the Mississippi River to the Gulf of Mexico. The local watershed supports diverse aquatic life and is important for regional biodiversity. Secondary treatment helps reduce nutrient loads that could otherwise contribute to algal blooms in downstream waters.
