Sulligent WWTP - Advanced Wastewater Treatment in Sulligent, Alabama

Sulligent WWTP is a municipal wastewater treatment facility located in Sulligent, Lamar County, Alabama, United States. The plant serves a population of approximately 1,484 residents, classifying it as a small community system under US EPA regulations. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,892.70 megaliters per year and an actual discharge volume of 719.23 megaliters per year, the plant operates well within its capacity. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Tombigbee River basin, ultimately reaching the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's rivers and estuaries.

The plant discharges into tributaries of the Tombigbee River, which flows southward to join the Mobile River and empty into Mobile Bay and the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and invertebrates, and provides critical habitat for migratory species. The advanced treatment helps reduce nutrient loading, which is important for preventing eutrophication in downstream waters.
