Farmersburg STP - Advanced Wastewater Treatment in Farmersburg, Indiana

Farmersburg STP is a municipal wastewater treatment facility located in Farmersburg, Sullivan County, Indiana, United States. The plant serves a small population of 1,180 residents, providing advanced treatment to protect local water quality. The facility operates with advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,135.62 units and an actual discharge volume of 567.81 units, the plant operates well within its capacity. As a US facility, it is subject to the Clean Water Act and likely operates under an NPDES permit issued by the Indiana Department of Environmental Management, which sets effluent limits to protect receiving waters. The treated effluent is discharged into a local water body, ultimately draining into the Wabash River basin. The Wabash River flows into the Ohio River, then the Mississippi River, and finally the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient loading, which is critical for preventing hypoxia in the Gulf of Mexico.

The plant discharges into a tributary of the Wabash River, which flows into the Ohio River and then the Mississippi River, eventually reaching the Gulf of Mexico. The Wabash River watershed supports diverse aquatic life and is an important ecological corridor. Advanced treatment at this plant helps minimize nutrient pollution, which can contribute to algal blooms and dead zones downstream.
