Kingston STP Wastewater Treatment Plant | Kingston, Michigan

Kingston STP is a municipal wastewater treatment plant located in Kingston, Tuscola County, Michigan, United States. The facility serves a small population of 428 residents, reflecting the rural character of the community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment as a minimum standard for municipal wastewater discharges. The plant provides secondary treatment, a biological process that removes biodegradable organic matter and suspended solids. With a designed capacity of 189.27 megaliters per year and an actual discharge volume of 113.56 megaliters, the plant operates well below its capacity, indicating room for future growth. The facility is not within 10 km of the coast but is within 50 km, placing it in a transitional inland-coastal zone. The treated effluent is discharged to local surface waters that ultimately drain into the Saginaw Bay of Lake Huron, part of the Great Lakes system. This watershed supports diverse aquatic life and provides drinking water for millions. The plant's performance is critical to protecting the bay's water quality and the ecological health of the Great Lakes.

The plant discharges into tributaries of the Saginaw River, which flows into Saginaw Bay, a shallow, nutrient-rich embayment of Lake Huron. The bay supports important fisheries, including walleye and yellow perch, and is a key migratory stopover for waterfowl. Nutrient loading from wastewater can contribute to algal blooms and hypoxia, making effective treatment essential for maintaining the bay's ecological balance.
