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

The Adena WWTP and Sewer System is a municipal wastewater treatment facility located in Adena, Jefferson County, Ohio. Serving a population of approximately 825 residents, the plant provides advanced treatment to ensure effluent quality meets environmental standards before discharge. The facility operates under the regulatory framework of the US Clean Water Act, which mandates National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. As a small community plant, it is designed to handle a capacity of 484.53 cubic meters per day, with a current discharge volume of 378.54 cubic meters per day. The advanced treatment process likely includes tertiary filtration or nutrient removal, common for plants in sensitive watersheds. The treated effluent is discharged into local streams that flow into the Ohio River, a major tributary of the Mississippi River system. This river network supports diverse aquatic life and provides drinking water for millions downstream. The plant's location in inland Ohio, away from coastal areas, reduces direct marine impact but contributes to the overall health of the Mississippi River basin.

The plant discharges into local waterways that drain into the Ohio River, which flows southwest to join the Mississippi River. The Ohio River watershed supports a variety of fish species and is an important migratory corridor for birds. The advanced treatment helps protect water quality in this ecologically significant river system, which supplies drinking water and supports recreation.
