The plant's advanced treatment helps reduce nutrient loading and protects downstream ecosystems.

The plant discharges to a tributary of the Ohio River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River watershed supports diverse aquatic species and is an important migratory corridor for fish. Advanced treatment at this plant helps minimize nutrient pollution, which can cause algal blooms and hypoxia in downstream waters.
