Pigeon Township RSD - Selvin, Indiana Wastewater Treatment Plant

Pigeon Township RSD is a municipal wastewater treatment facility located in Selvin, Warrick County, Indiana, serving a population of approximately 3,500 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The facility provides advanced treatment, going beyond the secondary treatment standard typically required for municipal plants of this scale. With a designed capacity of 946.35 cubic meters per day, the plant treats wastewater from the local community before discharging into the region's surface waters. The plant's discharge ultimately drains into the Ohio River basin, which flows into the Mississippi River and then to the Gulf of Mexico. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The advanced treatment level helps protect water quality in this important river system.

The plant discharges into local streams within the Ohio River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. This region supports diverse aquatic ecosystems, including fish and macroinvertebrate communities. The advanced treatment helps minimize nutrient loading and protect downstream water quality.
