Northwest Montana's Water Specialists
We treat water — not transactions.
Glacier Peak Water Systems was founded on a simple idea: every home in Northwest Montana deserves clean, safe, great-tasting water — and every recommendation should start with actually testing the water.
We're not a national chain. We don't pull systems off a shelf and hope they fit. We live in the Flathead Valley, we know the water here block by block, and we design every system specifically for the home it's going into.
From the smallest under-sink RO to full commercial treatment trains for vacation rentals, hotels, and breweries, our process is the same: test, listen, design, install, and stay involved for the life of the system.
Better Water in Five Steps
Every project starts with understanding your water — not selling you a system off the truck.
Free Water Test
We come to your home and test your water on-site — hardness, iron, pH, TDS, and more.
Water Analysis
We walk you through every reading in plain English so you know exactly what's in your water.
Custom Recommendation
If treatment makes sense, we design a system sized specifically for your water and household.
Professional Installation
Licensed install, clean work, programmed and tested before we leave.
Ongoing Support
Service plans, salt delivery, annual inspection — we don't disappear after install.
