DeMotte WWTP - Advanced Wastewater Treatment in Jasper County, Indiana

DeMotte WWTP is a municipal wastewater treatment plant located in Jasper County, Indiana, United States. The facility serves a population of about 3,234 and operates with advanced treatment processes, ensuring high-quality effluent before discharge. The plant has a designed capacity of 1,514.16 thousand cubic meters and currently treats 946.35 thousand cubic meters annually. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent water quality standards. Under the US Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits, which set limits on effluent quality to protect receiving waters. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River Basin. This region supports diverse aquatic life and is part of a larger watershed that flows to the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient loading, contributing to the health of downstream ecosystems.

The plant discharges into local streams within the Mississippi River Basin, which flows southward to the Gulf of Mexico. This watershed is ecologically significant, supporting diverse fish and wildlife habitats. Nutrient pollution from wastewater can contribute to hypoxic zones in the Gulf, making advanced treatment important for downstream water quality.
