BAXTER STP Wastewater Treatment Plant, Baxter, Tennessee

BAXTER STP is a municipal wastewater treatment plant located in Baxter, Tennessee, a small community in Putnam County. The plant serves a population of approximately 1,385 residents and operates as part of the region's water infrastructure. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 1,892.70 cubic meters per day and currently treats an average daily flow of 946.35 cubic meters, indicating it operates at about half its capacity. Under the U.S. Clean Water Act, secondary treatment is the minimum standard for municipal wastewater plants, ensuring compliance with National Pollutant Discharge Elimination System (NPDES) permit requirements. The plant's performance is regulated by the Tennessee Department of Environment and Conservation. Treated effluent from BAXTER STP is discharged into local streams that flow into the Cumberland River, a major tributary of the Ohio River and ultimately the Mississippi River. The Cumberland River basin supports diverse aquatic life and provides drinking water for downstream communities. The plant's location inland, away from coastal areas, reduces direct marine impact, but its discharge contributes to the overall water quality of the Cumberland watershed.

BAXTER STP discharges into local waterways that drain into the Cumberland River, a major tributary of the Ohio River and part of the Mississippi River system. The Cumberland River basin supports diverse aquatic ecosystems, including fish species such as bass and catfish, and provides habitat for freshwater mussels. The plant's secondary treatment helps protect downstream water quality, though nutrient loading from treated effluent can contribute to algal growth in receiving waters. The inland location minimizes direct coastal impacts.
