York Lagoon Wastewater Treatment Plant, York, Alabama

York Lagoon is a municipal wastewater treatment plant located on Moore Street in York, Sumter County, Alabama. The facility serves a population of about 2,700 people, classifying it as a small community system under U.S. Environmental Protection Agency (EPA) regulations. The plant provides secondary treatment, which is the standard level required by the Clean Water Act for municipal wastewater facilities. With a designed capacity of 2,271.24 cubic meters per day and an average discharge volume of 416.40 cubic meters per day, the plant operates well below its capacity, indicating room for future growth or seasonal variability. Treated effluent from York Lagoon is discharged into nearby streams that flow into the Tombigbee River, a major tributary of the Mobile River Basin. This basin ultimately drains into the Mobile Bay estuary, an ecologically important area supporting diverse aquatic life and coastal habitats. The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Alabama Department of Environmental Management.

York Lagoon discharges into local waterways that are part of the Tombigbee River watershed, which flows southward to join the Alabama River and form the Mobile River. The Mobile River Basin empties into Mobile Bay on the Gulf of Mexico, a productive estuary that supports fisheries, migratory birds, and marine species. The plant's secondary treatment helps protect downstream water quality in this sensitive coastal ecosystem.
