Henagar WWTP - Advanced Wastewater Treatment in Henagar, Alabama

Henagar WWTP is a municipal wastewater treatment facility located in Henagar, Alabama, serving a small population of 233 residents. The plant is situated in DeKalb County, a rural area in northeastern Alabama, and operates as part of the local infrastructure managed by the city. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 757.08 cubic meters per day and a current discharge volume of 378.54 cubic meters per day, the facility operates well within its capacity. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Alabama Department of Environmental Management, ensuring compliance with federal water quality standards. The treated effluent is discharged into local streams that drain into the Tennessee River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream water quality and aquatic habitats in this ecologically diverse region.

The plant's discharge enters small streams in the Tennessee River watershed, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This region supports diverse aquatic life, including fish and macroinvertebrates, and the advanced treatment helps minimize nutrient loading and protect downstream ecosystems.
