Clinton Township Water Hardness & Quality Report (2026)

The Charter Township of Clinton, located in Macomb County, Michigan, receives drinking water through the Public Services Department, Water and Sewer Division. Water is supplied by the Great Lakes Water Authority (GLWA) from the lower Lake Huron watershed and Detroit River intakes, and by the City of Mount Clemens from Lake St. Clair. Treatment occurs at GLWA's Detroit River water treatment plants and the Mount Clemens Water Treatment Plant, delivering treated water via distribution throughout Clinton Township and surrounding zones.

The supply originates from the Lake Huron watershed, encompassing seasonal streams draining into Lake Huron alongside the Detroit River, fed by Lake St. Clair, the Clinton River, Ecorse River, and transboundary inputs from Canada's Thames River, Little River, Turkey Creek, and Sydenham watershed. Underlying the Michigan Basin are Paleozoic carbonate rock formations, including Devonian limestones and dolomites, which interact with glacial tills and promote mineral dissolution, imparting a hard character to the surface water through prolonged carbonate-rock interaction.

Hard water leads to scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan while increasing energy costs. Dry skin, soap scum, and spotting on dishes and fixtures are common. Regular maintenance such as descaling appliances, vinegar rinses, and installing a water softener is recommended to protect plumbing. Water quality meets EPA and Michigan standards with no violations noted in recent reports; fluoride is added for dental health. Quality scores are rated good (B grade, 80/100) per third-party assessments, with treatment including disinfection and filtration.
