Traverse City Regional STP - Wastewater Treatment Plant in Traverse City, Michigan

The Traverse City Regional STP is a municipal wastewater treatment facility located in Traverse City, Michigan, serving a population of approximately 51,251. Situated on the shores of Grand Traverse Bay, the plant is part of the region's critical water infrastructure, supporting both residential and commercial needs in this Great Lakes community. As a US facility, the plant operates under the Clean Water Act and is regulated by an NPDES permit issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). For a population of this scale, secondary treatment is the federal minimum standard, though many plants in the Great Lakes basin employ advanced treatment to protect sensitive waters. The plant's designed capacity is 1.00 million gallons per day, indicating it is sized to handle the community's wastewater flows. The plant's treated effluent discharges into the Grand Traverse Bay watershed, which flows into Lake Michigan, one of the largest freshwater lakes in the world. This water body supports diverse aquatic life, including lake trout, whitefish, and migratory species, and is a vital resource for recreation and drinking water. The plant's performance directly affects the ecological health of the bay and the broader Great Lakes ecosystem.
