Rutherford WWTP - Secondary Treatment Plant in Gibson County, Tennessee

Rutherford WWTP is a municipal wastewater treatment facility located in Gibson County, West Tennessee, United States. The plant serves a small population of 1,280 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 1,400.60 million gallons per year and currently treats an average of 295.26 million gallons annually, indicating significant spare capacity. Under the U.S. Clean Water Act, secondary treatment is the minimum standard for municipal wastewater plants, and the facility operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Tennessee Department of Environment and Conservation. The treated effluent is discharged into local streams that drain into the Mississippi River watershed, ultimately reaching the Gulf of Mexico. The plant's operations help protect downstream water quality in the region's agricultural and natural areas, supporting aquatic life and recreational uses.

The plant discharges into tributaries of the Mississippi River, which flows into the Gulf of Mexico. This region is part of the larger Mississippi River Basin, a critical ecological corridor for migratory birds and aquatic species. The discharge contributes to nutrient loading concerns in the Gulf, where excess nitrogen and phosphorus can cause hypoxic zones. The plant's secondary treatment helps reduce organic pollutants but may not fully address nutrient removal, which is a growing focus for inland plants in the basin.
