Lineville Lagoon Wastewater Treatment Plant, Lineville, Alabama

Lineville Lagoon is a municipal wastewater treatment facility located in Lineville, Clay County, Alabama. The plant serves a small community of about 1,750 people and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. As a lagoon system, it provides biological treatment through natural processes in aerated or facultative ponds. The plant has a designed capacity of 1,892.70 cubic meters per day and currently discharges an average volume of 567.81 cubic meters per day, indicating it operates well below its capacity. The treatment level is secondary, which is the minimum standard for municipal wastewater treatment in the United States under the National Pollutant Discharge Elimination System (NPDES) permit program. The treated effluent from Lineville Lagoon is discharged to nearby creeks that flow into the Tallapoosa River, a major tributary of the Alabama River system. The Tallapoosa River 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 water quality of the river basin.

Lineville Lagoon discharges into local streams that are part of the Tallapoosa River watershed, which ultimately drains into the Alabama River and then to Mobile Bay. The Tallapoosa River is an ecologically important waterway supporting diverse fish and mussel species. The plant's secondary treatment helps protect downstream water quality by reducing organic pollutants and suspended solids before discharge.
