Eutaw Lagoon Wastewater Treatment Plant, Eutaw, Alabama

Eutaw Lagoon is a wastewater treatment facility located in Eutaw, Greene County, Alabama, serving a population of approximately 3,250 residents. The plant provides secondary treatment, a standard level for municipal wastewater in the United States under the Clean Water Act. The plant has a designed capacity of 3,331.15 million gallons and reports an annual discharge volume of 632.16 million gallons. As a lagoon-based system, it relies on natural biological processes to treat wastewater before discharge. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES), which sets effluent limits to protect water quality. The treated effluent from Eutaw Lagoon is discharged into local waterways that ultimately drain into the Tombigbee River basin, a major tributary of the Mobile River system. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's location inland, away from coastal areas, reduces direct marine impact, but its discharge contributes to the overall health of the regional river ecosystem.

Eutaw Lagoon discharges into the Tombigbee River basin, which flows southward to join the Alabama River and form the Mobile River, eventually emptying into the Mobile Bay estuary. This watershed supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream water quality and aquatic habitats.
