Its advanced treatment helps protect downstream aquatic ecosystems and supports regional water quality goals in the Ohio River watershed.

The plant discharges into a tributary of the Ohio River, which flows into the Mississippi River and then the Gulf of Mexico. The Ohio River basin supports diverse aquatic life and is a critical water resource for the region. Advanced treatment at this plant helps reduce nutrient loading, which is important for preventing eutrophication in downstream waters, including the Gulf of Mexico's hypoxic zone.
