Pearl River WWTP | Advanced Wastewater Treatment in Pearl River, Louisiana

Pearl River WWTP is an advanced wastewater treatment facility located in Pearl River, St. Tammany Parish, Louisiana. The plant serves a population of 2,179 and is part of the municipal infrastructure for the Pearl River community. It operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for discharges into surface waters. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 1,892.70 thousand gallons per day and an actual discharge volume of 965.28 thousand gallons per day, the facility operates well within its capacity. This advanced treatment level is typical for plants in sensitive watersheds or those discharging to ecologically important water bodies. The treated effluent is discharged into the Pearl River system, which flows into Lake Borgne and ultimately the Gulf of Mexico. The Pearl River basin supports diverse aquatic life and provides critical habitat for fish and wildlife. The plant's advanced treatment helps protect downstream water quality in this important coastal watershed.

The plant discharges into the Pearl River, which flows south through Louisiana and empties into Lake Borgne, a brackish estuary connected to the Gulf of Mexico. This watershed supports a variety of aquatic species and provides important nursery habitat for fish and shellfish. The advanced treatment level helps minimize nutrient loading and protects the ecological health of the downstream estuary and coastal waters.
