Golden Meadow STP - Advanced Wastewater Treatment in Golden Meadow, Louisiana

Golden Meadow STP is a municipal wastewater treatment facility located in Golden Meadow, Lafourche Parish, Louisiana. The plant serves a small population of 790 residents, providing advanced treatment to protect local water quality. As a facility in the United States, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 681.37 MLD and an actual discharge volume of 132.49 MLD, the plant operates well below its capacity, indicating room for future growth. The advanced treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The treated effluent is discharged into local waterways that drain into the Gulf of Mexico via the Barataria Basin and the Mississippi River Delta. This region supports diverse aquatic life, including fisheries and migratory birds. The plant's advanced treatment helps reduce nutrient loading, which is critical for mitigating hypoxia in the Gulf of Mexico.

The plant discharges into the Barataria Basin, a complex estuarine system that connects to the Gulf of Mexico. This watershed supports vital habitats for fish, shellfish, and waterfowl, and is part of the larger Mississippi River Delta ecosystem. Advanced treatment at this plant helps reduce nutrient pollution, which is a key factor in the Gulf of Mexico's hypoxic zone, an area of low oxygen that affects marine life.
