PURYEAR WWTP - Puryear, Tennessee Wastewater Treatment Plant

PURYEAR WWTP is a municipal wastewater treatment facility located in Puryear, Henry County, Tennessee. The plant serves a small community of approximately 750 residents, providing secondary treatment to meet state and federal water quality standards. The plant has a designed capacity of 227.12 million gallons per year and currently discharges 113.56 million gallons annually. As a secondary treatment facility, it utilizes biological processes to reduce organic matter and suspended solids, consistent with typical US plants serving small populations under the National Pollutant Discharge Elimination System (NPDES) permit program. The treated effluent is discharged into local waterways within the Tennessee River basin, which ultimately drains to the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream water quality in the region's rural watershed, supporting aquatic life and recreational uses.

The plant discharges into tributaries of the Tennessee River, which flows into the Ohio River and then the Mississippi River, eventually reaching the Gulf of Mexico. The local watershed supports diverse aquatic habitats and is important for regional biodiversity. The plant's secondary treatment helps reduce nutrient loading and protect downstream ecosystems from eutrophication.
