Brazil Regional WWTP - Clay County, Indiana Wastewater Treatment Plant

Brazil Regional WWTP is a municipal wastewater treatment facility located in Clay County, Indiana, serving a population of around 10,045. The plant is situated inland, away from coastal areas, and operates within the regulatory framework of the United States Clean Water Act. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the National Pollutant Discharge Elimination System (NPDES) permit program. Facilities of this scale typically employ biological treatment followed by disinfection to protect water quality. The plant discharges treated effluent to a local receiving water body, which ultimately drains into the Wabash River basin. The Wabash River flows southwest to the Ohio River, then to the Mississippi River and the Gulf of Mexico. This watershed supports diverse aquatic life and is an important ecological corridor in the Midwest.

The plant's discharge enters a tributary of the Wabash River, which flows through agricultural and forested landscapes in west-central Indiana. The Wabash River is a major tributary of the Ohio River, supporting diverse fish populations and providing habitat for migratory birds. Downstream, the Ohio River joins the Mississippi River, eventually reaching the Gulf of Mexico. The watershed is ecologically sensitive to nutrient loading, and the plant's treatment helps protect water quality in this interconnected system.
