Delcambre STP Wastewater Treatment Plant, Delcambre, Louisiana

Delcambre STP is a municipal wastewater treatment plant located at 339 South Central Street in Delcambre, Louisiana, within Vermilion Parish. The facility serves a population of approximately 2,168 residents and has a designed capacity of 1.00 million gallons per day, reflecting the scale of this small community. As a plant in the United States, Delcambre STP operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality. For small agglomerations like this, secondary treatment is typically required to meet effluent standards for biochemical oxygen demand and total suspended solids. The plant's treated effluent is discharged into local waterways that drain into the Vermilion River basin, ultimately reaching the Gulf of Mexico. This coastal region supports diverse aquatic life and is part of the larger Mississippi River Delta ecosystem, which is ecologically sensitive to nutrient loading and other wastewater impacts.

Delcambre STP discharges into the Vermilion River watershed, which flows southward through Louisiana's coastal marshes and into the Gulf of Mexico. The receiving waters support a variety of fish and shellfish species and are part of an important migratory corridor for waterfowl. The proximity to the Gulf of Mexico means that nutrient discharges can contribute to coastal eutrophication and hypoxic zones, making treatment performance critical for downstream ecosystem health.
