Eupora POTW - Secondary Wastewater Treatment in Eupora, Mississippi

Eupora POTW (Publicly Owned Treatment Works) is a municipal wastewater treatment facility located in Eupora, Webster County, Mississippi. The plant serves a population of approximately 2,328 residents, classifying it as a small community system under U.S. EPA guidelines. It is situated inland, away from coastal zones, and operates under the regulatory framework of the Clean Water Act. The plant provides secondary treatment, which is the standard level required by the EPA for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. With a designed capacity of 1,983.55 thousand gallons per day and an average discharge volume of 870.65 thousand gallons per day, the plant operates at about 44% capacity, indicating room for future growth. The treated effluent is discharged into a local water body, likely a tributary of the Tombigbee River basin, which flows southward to Mobile Bay and the Gulf of Mexico. The plant plays a key role in protecting local water quality and downstream ecosystems, including the Mobile Bay estuary, which supports diverse aquatic life and commercial fisheries.

Eupora POTW discharges into a receiving water body within the Tombigbee River basin, which ultimately drains into Mobile Bay and the Gulf of Mexico. The Mobile Bay estuary is a critical habitat for fish, shellfish, and migratory birds. Secondary treatment helps reduce nutrient and organic loads, mitigating risks of eutrophication and hypoxia in downstream waters. The plant's inland location reduces direct marine impact, but its discharge still influences the broader watershed health.
