Negaunee STP - Wastewater Treatment Plant in Negaunee Township, Michigan

Negaunee STP is a municipal wastewater treatment facility located in Negaunee Township, Marquette County, Michigan. Serving a population of approximately 4,576, the plant is part of the region's infrastructure for managing domestic wastewater. Its designed capacity is 1.00 million gallons per day, reflecting the scale of the community it supports. Under the U.S. Clean Water Act, plants of this size are typically required to meet secondary treatment standards through National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy. These permits set effluent limits to protect water quality. The plant's treatment process is designed to comply with these regulatory requirements. The plant discharges into the Lake Superior basin, the largest of the Great Lakes. Lake Superior is a critical freshwater resource with sensitive aquatic ecosystems. The plant's operations help protect downstream water quality, supporting recreational use and wildlife habitat in the region.

The plant discharges into the Lake Superior watershed, which ultimately drains into the Great Lakes system and the St. Lawrence River. Lake Superior is a cold, oligotrophic lake with low nutrient levels, making it sensitive to nutrient pollution. The plant's treatment helps maintain water quality for fish populations and recreational activities in the region.
