Why Montrose Hardness Changes With the Seasons
Water softener installation in Montrose, CO starts with a number most people never see: the hardness of the treated water leaving the Project 7 plant, which averaged 128 mg/L in 2025 and reached 181 mg/L in January. Our Grand Junction team comes to you in Montrose, runs a free water test at your kitchen tap, and sizes a softener to the water you actually have. Call (970) 773-6439 to set a time.
Montrose city water is surface water. Project 7 Water Authority's 2026 water quality report lists its sources as the Gunnison River Tunnel, Cerro Reservoir and Fairview Reservoir, and the plant treats water for the City of Montrose along with Delta, Olathe and several rural districts. River water picks up more dissolved minerals when flows are low in winter and less when spring runoff dilutes it. That is why the monthly hardness numbers in Project 7's 2025 composite read like a ski season in reverse: high in January, lowest in early summer, then climbing again through the fall.
A softener that is set up for the yearly average will run short of capacity in the months that matter most. That is the main point of this page. If you want the wider picture of Montrose water, including what we look for beyond hardness, see our Montrose service area page.

Montrose Hardness by the Numbers
What Project 7's 2025 Data Shows
Finished-water readings from the plant that supplies Montrose. Your tap test confirms what reaches your house.
January: 181 mg/L
The hardest month of 2025. At 17.1 mg/L per grain, that works out to roughly 10.6 grains per gallon, which edges just past the 180 mg/L line into the very hard range.
June: 103 mg/L
The softest month, about 6 grains per gallon. Spring runoff dilutes the minerals. A household that only tested its water in June would come away thinking the problem was mild.
Yearly average: 128 mg/L
About 7.5 grains per gallon. Water from 121 to 180 mg/L is classed as hard, so Montrose's annual average lands in the hard category even before the winter peak.
Calcium does most of it
Of that 128 mg/L average, Project 7 reports 92 mg/L as calcium hardness and 36 mg/L as magnesium hardness. Calcium carbonate is the chalky white scale you find on shower heads and inside water heaters.
What a Softener Fixes in a Montrose Home
Options
Softening and What Pairs With It in Montrose
Hardness is one part of Montrose water. Here is how the pieces fit.
Salt-based softener
The standard fix for hard water and the most direct way to stop scale. Sized to your household and to Montrose's winter readings. Details on our softener installation page.
HydraShield Elite
Some homeowners would rather not haul salt. The HydraShield Elite is our salt-free whole-house system, and we can talk through how it compares for Montrose water once we have your test results.
Whole-house carbon filtration
Montrose water is disinfected with chloramine, and a softener does not remove it. A whole house filtration system in front of the softener handles taste, odor and disinfection byproducts and protects the resin.
Whole-home reverse osmosis
If you want the dissolved solids out as well as the hardness, a whole-home RO system is the most complete option. It usually pairs with softening ahead of the membrane.
How It Works
From Test to Soft Water in Montrose
1. We test at your tap
Our Grand Junction team drives to Montrose and measures hardness, chlorine residual and total dissolved solids at your sink. The free water test costs nothing and carries no obligation.
2. We size for the hard months
We compare your reading with Project 7's seasonal range, count the people and bathrooms in the house, and recommend a softener capacity that will hold up in January.
3. We install and program it
We plumb the softener in at the main line, set the hardness value and regeneration schedule, and show you how to check salt and adjust settings as the seasons change.
