Fall Creek Plant Wastewater Treatment Facility, Madison County, Indiana

Fall Creek Plant is a municipal wastewater treatment facility located in Madison County, Indiana, United States. Serving a population of approximately 31,103, the plant is part of the region's water infrastructure, managing wastewater from residential and commercial sources in the area. The plant operates under the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For facilities serving populations around 30,000, secondary treatment is typically mandated to reduce organic matter and suspended solids before discharge. The plant's treatment processes and capacity are designed to meet these federal and state standards. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River Basin. The plant plays a key role in protecting the water quality of receiving streams and downstream environments, including the Ohio River and the Gulf of Mexico, by reducing pollutant loads and preventing eutrophication.

Fall Creek Plant discharges into local tributaries of the White River, which flows into the Wabash River and eventually the Ohio River and Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's operations help maintain water quality in this agriculturally influenced region, reducing nutrient and sediment loads that could impact the Gulf of Mexico's hypoxic zone.
