PINSON LAGOON Wastewater Treatment Plant, Pinson, Tennessee

PINSON LAGOON is a municipal wastewater treatment facility located in Pinson, Tennessee, a small community in Madison County. The plant serves a population of approximately 574 residents, classifying it as a small-scale treatment system typical of rural areas in the southeastern United States. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 151.42 million gallons per year and an actual discharge volume of 113.56 million gallons per year, the facility operates below its capacity, indicating room for future growth. As a lagoon-based system, it likely uses natural biological processes to treat wastewater before discharge. The treated effluent is released into local streams that drain into the Forked Deer River system, part of the Mississippi River basin. This watershed ultimately flows into the Mississippi River and then the Gulf of Mexico, making the plant's performance important for downstream water quality in the region.

The plant discharges into tributaries of the Forked Deer River, which flows into the Hatchie River and then the Mississippi River. This watershed supports diverse aquatic life and provides habitat for fish and migratory birds. The Mississippi River basin is ecologically significant, and nutrient management from small plants like PINSON LAGOON contributes to overall water quality in the Gulf of Mexico.
