ABOUT

Drinking Water System Services came together in 2017, after 12 years of doing business operating a couple of large & small water systems.  We decided to expand into additional water systems, provide on demand sampling services and also include system sanitization services when poor water quality issues are present.  These systems were either chlorinated, surface water with multiple media filters or the simpler untreated or filtered ground water system.  Our niche is dealing with home loan/refinancing well testing and DEQ PWS site sampling services.

We have been residents of the Flathead valley for over 30 years and have witnessed a lot of changes.  As the farmland disappears and new developments bring additional water system needs and quality issues, we are your source to ensure you are getting safe drinking water.  You rely on the government to inspect your food and your restaurant establishments, as well as set standard testing requirements for public drinking water, but when it comes to your personal drinking water, only you are responsible for inspecting its quality.   What's in your drinking water?
