CLAYTON STP discharges into local streams that are part of the White River basin, which flows into the Wabash River and then the Mississippi River, eventually reaching the Gulf of Mexico. The plant's advanced treatment helps protect these waterways from nutrient pollution, which can cause algal blooms and hypoxia in the Gulf. The surrounding area is primarily agricultural, so the plant's nutrient removal is critical for maintaining downstream water quality.
