Stoney Creek WWTP | Advanced Wastewater Treatment in Madison County, Alabama

Stoney Creek WWTP is a municipal wastewater treatment facility located in Madison County, Alabama, United States. The plant serves a small population of 240 residents, reflecting its role in a rural or suburban community within the Tennessee Valley region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 189.27 megaliters and an annual discharge volume of 102.21 megaliters, the facility operates under the regulatory framework of the U.S. Clean Water Act, administered by the Alabama Department of Environmental Management. Plants of this scale in the U.S. are typically required to meet stringent effluent limits through National Pollutant Discharge Elimination System (NPDES) permits. The treated effluent from Stoney Creek WWTP is discharged into local waterways that ultimately drain into the Tennessee River basin. The Tennessee River flows westward through Alabama before joining the Ohio River and eventually the Mississippi River, making this plant part of a larger watershed that supports diverse aquatic life and provides water resources for communities downstream.

The plant's discharge enters streams within the Tennessee River watershed, which flows through northern Alabama and into the Ohio River. This basin supports a variety of fish and wildlife species, including several endemic mussels and fish. The advanced treatment level helps protect water quality in this ecologically sensitive region by reducing nutrient loads that could otherwise contribute to algal blooms and habitat degradation downstream.
