The plant discharges into tributaries of the Wabash River, which flows into the Ohio River and then the Mississippi River, eventually reaching the Gulf of Mexico. The Wabash River basin supports diverse aquatic life and is an important ecological corridor. Advanced treatment helps reduce nutrient loading, which is critical for preventing hypoxia in the Gulf of Mexico.
