Hiawassee WWTP - Advanced Wastewater Treatment in Hiawassee, Georgia

Hiawassee WWTP is a municipal wastewater treatment plant located in Hiawassee, Towns County, Georgia, United States. The facility serves a population of approximately 1,130 residents, providing advanced treatment to protect public health and the environment. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. As an advanced treatment facility, it goes beyond secondary treatment standards to achieve higher removal of nutrients and other pollutants, which is particularly important for sensitive receiving waters. The treated effluent from Hiawassee WWTP is discharged into the Hiwassee River watershed, a tributary of the Tennessee River system. The Tennessee River flows into the Ohio River, then the Mississippi River, and ultimately reaches the Gulf of Mexico. The plant's advanced treatment helps reduce nutrient loading that could contribute to downstream eutrophication and hypoxia in the Gulf.

The plant discharges into the Hiwassee River, which flows into the Tennessee River, a major tributary of the Ohio-Mississippi river system. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The advanced treatment at Hiawassee WWTP helps minimize nutrient pollution that can cause algal blooms and oxygen depletion in receiving waters, protecting both local streams and the far-field Gulf of Mexico ecosystem.
