HAYNESVILLE STP - Wastewater Treatment Plant in Haynesville, Louisiana

HAYNESVILLE STP is a municipal wastewater treatment plant located in Haynesville, Claiborne Parish, Louisiana. It serves a population of approximately 3,900 residents, making it a small-scale facility typical of rural communities in the southern United States. As a U.S. plant, HAYNESVILLE STP operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality. For a plant of this size, secondary treatment is the standard requirement, ensuring that effluent meets federal water quality standards before discharge. The plant's treated effluent is discharged into local waterways that drain into the Red River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. This connection to a major river system underscores the importance of effective treatment to protect downstream aquatic ecosystems and water quality.

HAYNESVILLE STP discharges into local streams that flow into the Red River, a major tributary of the Mississippi River. The Mississippi River carries water to the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones. Effective treatment at this plant helps reduce nutrient loads and protects aquatic life in the Red River basin and beyond.
