Sorrento STP - Advanced Wastewater Treatment Plant in Sorrento, Louisiana

Sorrento STP is a municipal wastewater treatment facility located in Sorrento, Ascension Parish, Louisiana, United States. The plant serves a small population of 1,119 residents, providing advanced treatment to protect local water quality. The plant operates with advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 567.81 units and an average daily discharge of 340.69 units, the facility operates below its capacity. As a US plant, it is subject to the Clean Water Act and likely operates under an NPDES permit issued by the Louisiana Department of Environmental Quality. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River basin. The plant's advanced treatment helps protect downstream ecosystems, including the Mississippi River Delta and the Gulf of Mexico, by reducing nutrient loads that can contribute to hypoxic zones.

The plant discharges into a tributary of the Mississippi River, which flows through Louisiana and into the Gulf of Mexico. The Mississippi River basin supports diverse aquatic life and is a critical migratory corridor for birds and fish. Advanced treatment at this plant helps reduce nutrient pollution, which is a key concern for the Gulf of Mexico's hypoxic zone.
