Gibson Wastewater Treatment Plant, Gibson, Tennessee - USA

The Gibson wastewater treatment plant is located at 202 Austin Peay Memorial Highway in Gibson, Tennessee, serving a small population of 414 residents. As a municipal facility in rural West Tennessee, it plays a key role in managing local wastewater for this community. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. The facility has a designed capacity of 113.56 million gallons per day and currently discharges an average of 79.49 million gallons per day, indicating it operates below capacity. Under the National Pollutant Discharge Elimination System (NPDES), the plant must meet effluent limits to protect water quality. The treated effluent is discharged into nearby streams that drain into the Forked Deer River system, eventually reaching the Mississippi River and the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional water quality, particularly in the Mississippi River basin.

The plant discharges into local tributaries of the Forked Deer River, which flows into the Mississippi River and ultimately the Gulf of Mexico. This watershed supports diverse aquatic species and is an important migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream ecosystems from eutrophication and oxygen depletion.
