North Branch WWTP - Secondary Treatment Facility in North Branch Township, Michigan

North Branch WWTP is a municipal wastewater treatment plant located in North Branch Township, Lapeer County, Michigan. The facility serves a small community of approximately 991 residents, reflecting its role in managing local domestic wastewater. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal facilities. With a designed capacity of 492.10 volume units and a current discharge volume of 416.40, the plant operates within its capacity. As a U.S. facility, it operates under an NPDES permit issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), ensuring compliance with federal and state water quality standards. The treated effluent is discharged into a local waterway within the Saginaw Bay watershed, which ultimately drains into Lake Huron. This connection to the Great Lakes ecosystem underscores the plant's role in protecting downstream water quality and aquatic habitats.

The plant discharges into a tributary of the Saginaw River system, which flows into Saginaw Bay and then Lake Huron. This watershed supports diverse aquatic life and is important for regional fisheries. The secondary treatment process helps reduce nutrient and pollutant loads, protecting the downstream Great Lakes ecosystem from eutrophication and contamination.
