ROSEPINE WASTEWATER SYS - Advanced Treatment Plant in Rosepine, Louisiana

ROSEPINE WASTEWATER SYS is a municipal wastewater treatment facility located on C Dees Road in Rosepine, Vernon Parish, Louisiana. The plant serves a population of approximately 1,500 residents, classifying it as a small-scale treatment system within the state's wastewater infrastructure. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,135.62 m³/day and an average discharge volume of 757.08 m³/day, the plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. Louisiana's Department of Environmental Quality (LDEQ) oversees permitting and compliance for plants of this scale. The treated effluent is discharged into local waterways that drain into the Calcasieu River basin, ultimately reaching the Gulf of Mexico. This region supports diverse aquatic habitats and is important for migratory fish and waterfowl. The plant's advanced treatment helps protect downstream water quality in a state with significant wetland and coastal resources.

The plant discharges into streams within the Calcasieu River watershed, which flows southward through Louisiana's piney woods and coastal marshes before emptying into the Gulf of Mexico. This region is ecologically sensitive, supporting diverse aquatic life including fish, amphibians, and migratory birds. Advanced treatment reduces nutrient loading, helping to mitigate eutrophication risks in downstream estuaries.
