Matthews WWTP - Grant County, Indiana Wastewater Treatment Plant

Matthews WWTP is a municipal wastewater treatment facility located in Grant County, Indiana, United States. The plant serves a small population of around 700 residents, reflecting its role in a rural community. It operates under the regulatory framework of the U.S. Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level required for most municipal facilities in the United States. Its designed capacity is 416.39 units, with a current discharge volume of 416.40 units, indicating near-full utilization. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a stream or river within the Mississippi River Basin. The plant's operations help protect downstream water quality in the region, supporting aquatic life and recreational uses. As a small facility, it plays a key role in managing local wastewater and preventing pollution in the surrounding environment.

The plant discharges into a receiving water body within the Mississippi River Basin, which ultimately drains into the Gulf of Mexico. This watershed supports diverse aquatic ecosystems and is important for regional agriculture and recreation. Proper treatment helps reduce nutrient loading, which can contribute to hypoxia in the Gulf.
