ALMENA WWTP - Secondary Wastewater Treatment in Town of Clinton, Wisconsin

ALMENA WWTP is a municipal wastewater treatment facility located in the Town of Clinton, Barron County, Wisconsin, United States. The plant serves a population of approximately 754 residents, reflecting a small rural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 541.31 units and an average daily discharge of 177.91 units, the facility operates well below its capacity, indicating room for future growth. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources, ensuring compliance with water quality standards. The treated effluent is discharged into a local water body, likely a stream or river within the Red Cedar River basin, which flows into the Chippewa River and ultimately the Mississippi River. This downstream connection highlights the plant's role in protecting regional water quality and aquatic habitats in the Upper Mississippi River watershed.

The plant discharges into a local watercourse that is part of the Red Cedar River watershed, which drains into the Chippewa River and then the Mississippi River. This region supports diverse aquatic life, including fish species such as walleye and smallmouth bass. The plant's secondary treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality for recreational and ecological uses.
