Gillette vs Laramie Water Quality
Side-by-side water quality comparison for two Wyoming cities.
If you are comparing Gillette and Laramie water quality - whether moving, choosing between the two, or curious about a relative's water - here is what the data shows.
Hardness comparison
Gillette has dramatically harder water at 245 PPM versus Laramie at 66 PPM, a difference of 179 PPM. At 245 PPM, Gillette residents should budget for a water softener ($600-$1,500 installed). Without one, expect scale buildup on fixtures, reduced water heater efficiency, and $800-$1,200/year in hidden costs. Laramie has moderate hardness where a softener is optional.
This difference has real practical impact. Gillette homeowners deal with scale buildup on water heaters, extra soap and detergent use, and shorter appliance lifespans that Laramie residents largely avoid.
Water sources and why they differ
Water sources differ: Gillette draws from Local wells in Powder River Basin, while Laramie uses Albany County groundwater. The mix of groundwater and surface water explains much of the hardness difference.
What this means for you
If you are moving from Laramie to Gillette, you will notice the water difference. Budget for a water softener and expect to use more soap and detergent until you install one.
