SEYMOUR STP - Seymour, Indiana Wastewater Treatment Plant

SEYMOUR STP is a municipal wastewater treatment plant located in Seymour, Indiana, serving a population of about 19,009. The facility is situated in Jackson County and is part of the region's essential water infrastructure. As a medium-sized agglomeration, the plant plays a key role in protecting local water quality. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For communities of this scale, secondary treatment is typically mandated to reduce organic pollutants and suspended solids. The facility's treatment processes are designed to meet state and federal effluent limits. The treated effluent from SEYMOUR STP is discharged into a receiving water body that ultimately drains into the Mississippi River Basin. This watershed supports diverse aquatic life and provides water resources for downstream communities. Proper treatment helps prevent nutrient pollution and protects the ecological health of the region's waterways.

SEYMOUR STP discharges into a local waterway that flows into the Mississippi River Basin, eventually reaching the Gulf of Mexico. The watershed supports a variety of fish and wildlife species, and maintaining high water quality is essential for recreational uses and drinking water supplies downstream. Nutrient loading from wastewater can contribute to algal blooms, so effective treatment is critical for ecosystem health.
