Water Hardness in Laramie, Wyoming

What 150 PPM Means for Your Home in Laramie

At 150 ppm, Laramie's water is moderately hard. This is the threshold where most homeowners begin to notice real effects: white scale buildup on faucets and showerheads, reduced soap lathering that leads to using more shampoo and detergent, spots on dishes even with rinse aid, and a chalky film on shower glass. Your water heater is beginning to accumulate mineral deposits that reduce its energy efficiency by 10 to 15 percent. A water softener or salt-free conditioner is worth considering at this level, particularly if you have a tank-style water heater, multiple bathrooms, or a large household that uses significant amounts of hot water.

Water Source and Treatment at City of Laramie

Laramie's water is supplied by City of Laramie and sourced primarily from a combination of surface water and groundwater sources. This blended approach helps the utility balance water quality, availability, and seasonal demand. The 150 ppm hardness in Laramie reflects the weighted average of these different sources, and actual hardness may fluctuate slightly depending on which sources are active at any given time. The water has a pH of 7.5, which is near neutral, and total dissolved solids of 235 ppm (moderate).

Estimated Cost of Hard Water in Laramie

The Water Quality Association estimates that hard water costs the average household about 30 cents per grain per gallon per person per year in combined expenses from increased soap and detergent usage, reduced appliance efficiency, higher energy bills from scale-encrusted water heaters, and premature appliance and plumbing replacement. For a typical Laramie household of 2.5 people with water at 150 ppm (8.8 gpg), this translates to approximately $7 per year. Over 10 years, that adds up to $66 in avoidable costs — often more than the total cost of installing and operating a water softener.
