SHARON LAGOON Wastewater Treatment Plant, Sharon, Tennessee

SHARON LAGOON is a municipal wastewater treatment plant located in Sharon, Weakley County, Tennessee. The facility serves a population of about 1,025 residents and operates as a secondary treatment plant, which is standard for small communities in the United States. The plant has a designed capacity of 567,810 gallons per day and currently treats an average daily flow of 511,030 gallons, indicating it operates below its design capacity. As a US facility, it is subject to the Clean Water Act and likely operates under an NPDES permit issued by the Tennessee Department of Environment and Conservation, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant plays a key role in protecting the region's water resources by reducing organic pollutants and nutrients before discharge, supporting downstream aquatic ecosystems.

The plant discharges into tributaries of the Obion River, which flows into the Mississippi River and eventually the Gulf of Mexico. The region is part of the Mississippi River watershed, which is ecologically significant for migratory birds and aquatic life. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf of Mexico.
