Cumming Twp Rose City WWS - Rose City, Michigan Wastewater Treatment Plant

Cumming Twp Rose City WWS is a municipal wastewater treatment facility located at 2700 Beechwood Road in Rose City, Michigan, within Ogemaw County. The plant serves a population of approximately 2,004 residents, classifying it as a small community system under US EPA guidelines. The facility provides secondary treatment, which is the minimum standard required by the US Clean Water Act for municipal wastewater plants. With a designed capacity of 605.66 units and a discharge volume of 605.67 units, the plant operates near its design capacity, reflecting the demands of the local community. As a small plant in Michigan, it is subject to state-level NPDES permitting administered by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The treated effluent is discharged into local waterways that drain into the Saginaw Bay watershed, ultimately reaching Lake Huron. The plant plays a key role in protecting the region's surface water quality, supporting aquatic habitats, and maintaining the ecological health of the Great Lakes basin.

The plant discharges into tributaries of the Saginaw River system, which flows into Saginaw Bay and then Lake Huron. This watershed supports diverse aquatic life, including fish species such as walleye and perch, and provides important migratory corridors for birds. The facility's secondary treatment helps reduce nutrient loading and organic pollutants, mitigating the risk of eutrophication in the bay and protecting downstream Great Lakes water quality.
