Campti STP Wastewater Treatment Plant, Campti, Louisiana

Campti STP is a municipal wastewater treatment facility located in Campti, Natchitoches Parish, Louisiana. The plant serves a small community of about 1,035 people, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. The plant has a designed capacity of 567.81 cubic meters per day and currently discharges an average volume of 454.25 cubic meters per day, indicating operational capacity below design levels. As a U.S. facility, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into nearby bayous that flow into the Red River, a major tributary of the Mississippi River. The Red River basin supports diverse aquatic life and provides drinking water for communities downstream. The plant's secondary treatment helps reduce nutrient and pathogen loads, contributing to the ecological health of the watershed.

The plant discharges into Campti Bayou, which flows into the Red River, a major tributary of the Mississippi River. The Red River basin supports a variety of fish and wildlife species, including several threatened and endangered species. Downstream, the Mississippi River carries treated effluent to the Gulf of Mexico, where nutrient loads can contribute to hypoxic zones. Secondary treatment at this plant helps mitigate local and downstream impacts.
