Overview
DENMARK WWTP serves the village of Denmark, Wisconsin, treating wastewater for approximately 2,036 residents. The plant operates under the U.S. Clean Water Act framework with a designed capacity of 1.00 million gallons per day.
DENMARK WWTP is a municipal wastewater treatment facility located at 406 Mahlik Lane in Denmark, Wisconsin, serving a population of about 2,036. The plant is situated in Brown County and operates as part of the village's public infrastructure. As a small-scale facility, it plays a key role in managing local wastewater and protecting regional water quality. The plant's designed capacity is 1.00 million gallons per day, reflecting its service to a small community. Under the U.S. Clean Water Act, facilities of this size are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the Wisconsin Department of Natural Resources. These permits set effluent limits to protect receiving waters. The treated effluent from DENMARK WWTP discharges into local waterways that ultimately drain into Lake Michigan, part of the Great Lakes system. Lake Michigan is a vital freshwater resource supporting diverse aquatic life, recreational activities, and municipal water supplies. The plant's operations are critical to maintaining water quality in this sensitive watershed.
Environmental context
The plant discharges into streams that flow into the Lake Michigan basin, a major freshwater ecosystem. Lake Michigan supports a wide range of fish species, including lake trout and whitefish, and provides habitat for migratory birds. Protecting this watershed from nutrient pollution and pathogens is essential for maintaining ecological balance and public health.
