It serves a population of approximately 1,000 residents, classifying it as a small community facility within the state's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. With a designed capacity of 378.54 cubic meters per day and an average discharge volume of 340.69 cubic meters per day, the facility operates at a high utilization rate. As a US plant, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Saginaw Bay of Lake Huron, part of the Great Lakes system. This watershed supports diverse aquatic life and provides recreational and drinking water resources. The plant's operation helps protect downstream ecosystems from nutrient pollution and pathogens.

Environmental context

The plant discharges into a tributary of the Saginaw River, which flows into Saginaw Bay, a shallow bay of Lake Huron. This region is ecologically sensitive, supporting fish spawning grounds and migratory waterfowl. Nutrient loading from wastewater can contribute to algal blooms in the bay, making secondary treatment and proper nutrient management critical for maintaining water quality in the Great Lakes basin.
