West College Corner WWTP - Advanced Wastewater Treatment in Union County, Indiana

West College Corner WWTP is a municipal wastewater treatment facility located on Brookville Road in Union County, Indiana. The plant serves a small community of approximately 2,023 residents, providing advanced treatment to protect public health and the environment. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent water quality standards for its receiving waters. The treated effluent from the plant discharges into local streams that are part of the Ohio River watershed. The Ohio River ultimately flows into the Mississippi River and then to the Gulf of Mexico. This plant plays a key role in maintaining water quality in the region, supporting aquatic life and downstream ecosystems.

The plant discharges into tributaries of the Whitewater River, which flows into the Ohio River near Lawrenceburg, Indiana. The Ohio River is a major tributary of the Mississippi River, draining into the Gulf of Mexico. The local watershed supports diverse aquatic species and is an important corridor for migratory fish. Advanced treatment helps reduce nutrient loading, which is critical for preventing algal blooms in downstream waters.
