Livonia Water Hardness & Quality Report (2026)

The City of Livonia Water Utility serves Wayne County, Michigan, contracting with the Detroit Water and Sewage Department (DWSD) and Great Lakes Water Authority (GLWA) to purchase approximately 700 million cubic feet of water annually. The primary source is the Detroit River, drawn from the expansive Detroit River watershed and treated at GLWA's Springwell Water Treatment Plant before distribution. The utility provides drinking water to residential, commercial, and industrial customers across Livonia's approximately 36 square miles in southeast Michigan.

The Detroit River watershed drains into Lake St. Clair and connects to broader Great Lakes hydrology, including cross-border Canadian tributaries from the Rouge River, Ecorse River, and Sydenham watersheds. Underlying geology consists of Devonian-era limestone and dolomite bedrock layers prevalent in Michigan's Lower Peninsula, which naturally impart minerals to the surface water supply through carbonate dissolution during river flow. This interaction with carbonate-rich formations produces a hard supply characteristic of the regional sedimentary geology.

Hard water in Livonia causes scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. White deposits form on glassware and fixtures, increasing energy costs from mineral accumulation. Maintenance includes regular flushing of water heaters, installing scale-inhibiting filters, and vinegar descaling. A water softener is recommended to improve soap efficiency and reduce skin dryness. Water quality earns an A rating with no EPA violations; the 90th percentile lead level is 8.89 ppb, below the 15 ppb Action Level; pH averages 7.2–8.4, and treatment at Springwell Plant includes filtration, disinfection, and corrosion control.
