What Makes Fishers's Water Unique?
Local geology and source profile
Fishers, Indiana, in Hamilton County north of Indianapolis — one of America's fastest-growing cities, consistently ranked among the nation's best places to live — draws its municipal water supply through the Citizens Energy Group regional water system (serving the Indianapolis metropolitan area), sourcing from Geist Reservoir (an impoundment on Fall Creek in Hamilton County) and from White River riverbank infiltration galleries along the Indianapolis Westfield Water Treatment corridor. Citizens Energy distributes treated water to Fishers and Hamilton County. Water hardness in Fishers measures 158 mg/L — classified as hard.
Fishers' hard supply reflects Hamilton County's geology underlying the Fall Creek and White River watersheds. The Hamilton County–Indianapolis Plain is underlain by thick Quaternary Wisconsin glacial till — a calcareous till derived from the Silurian Niagaran Dolomite and Devonian Detroit River Group carbonate bedrock of central Indiana. Glacial outwash sands and gravels in the Fall Creek Valley and White River Valley contribute dissolved calcium and bicarbonate from calcareous outwash reworked from the underlying carbonate bedrock. The Silurian Niagaran Dolomite (including the Salamonie Dolomite and Kokomo Limestone) of Hamilton County is a particularly reactive calcareous formation that influences both surface water runoff and groundwater quality throughout the county.
At 158 mg/L, Fishers residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. Citizens Energy Group consistently delivers water meeting all Indiana DWE and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from the Geist Reservoir (Fall Creek watershed) and White River groundwater infiltration gallery via the Citizens Energy Group Indianapolis system — the Hamilton County Quaternary glacial outwash and the Silurian–Devonian Niagaran Dolomite and Detroit River Group carbonates beneath the Indiana glacial plain; hard supply at 158 mg/L in Hamilton County.
