BUNKIE STP Wastewater Treatment Plant, Bunkie, Louisiana

BUNKIE STP is a municipal wastewater treatment facility located at 628 East Oak Street in Bunkie, Avoyelles Parish, Louisiana. Serving a population of about 4,100, the plant is part of the region's infrastructure for managing domestic wastewater from this small community in central Louisiana. As a US facility, BUNKIE STP operates under the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point-source discharges. The Louisiana Department of Environmental Quality oversees permitting and compliance within the state. The plant's treated effluent discharges into local waterways that ultimately drain into the Atchafalaya River basin, a major distributary of the Mississippi River. This watershed supports diverse aquatic life and provides critical habitat in the Mississippi River Delta ecosystem, which flows into the Gulf of Mexico.

The plant's discharge enters the Atchafalaya River basin, which flows south through Louisiana's swamp and marsh ecosystems before reaching the Gulf of Mexico. This region is ecologically sensitive, supporting diverse fish, bird, and reptile species. The Atchafalaya Basin is the largest swamp in the United States and plays a vital role in flood control and nutrient cycling, making proper wastewater treatment essential for protecting downstream water quality.
