Northwest Water Treatment, Inc. is a family owned, father/son business founded by Glenn Karn in 1996. Glenn's son, Derrick Karn, does water system installation and service. Glenn has worked in water treatment industry in 1973 specializing in water testing and analysis, water system design, manufacturing, installation, service, and warranty service.
When you call, an onsite test will be scheduled to determine the causes of your water quality issues. Within 48 hours of your onsite test you will receive a fixed-fee quote for a custom-designed water treatment system. It will include all equipment, materials, labor, travel, and, if needed, a follow-up to tweak your system.
View these photos of a few of the well water, municipal water, and sea water filtration, softening, and treatment systems we designed and installed. Water testing, water analysis, and in many cases, pilot testing were completed before each system was designed. See systems for home owners, communities, commercial applications, and aquaculture companies.
In doing my research for this type of service, I was continually referred back to this agency by others because of their expertise in water filtration. The owners came to my home twice and did two different water samples and then Glenn, the owner, and his son Derrick were nice enough to sit down and explain the need for each piece of the system they recommended.
If you use well water in your home or community in the service area listed below right, are disappointed with your water quality, and ready to take action to improve it - you are eligible for a free, no-obligation, on-site well-water quality testing and analysis.

Quality testing and analysis enables us to determine the causes of your water quality issues and how to affordably solve them with a water treatment system so that you can enjoy delicious well water and sparkling fixtures.

Excellent and fast service. Called on Tuesday, water testing on Wednesday, and installation on Friday. Derrick answered every question we had, was on-time, and came out in the unexpected snow! THANK YOU!

I purchased a really good filtration system from here. The guy behind the counter was nice enough to show me how to install it. Five stars.

Excellent service! Northwest Water Treatment suggested a modest water filter that is just perfect for us. They did a great install. They are very courteous and easy to work with. Highly recommended.

My wife and I just purchased a new home and knew that we needed a water filtration system. We had Sulfur, Iron, Manganese and total coliform in our water. It smelled terrible and had a metal taste to it as well.
When I called Glen at Northwest Water Treatment, he was prompt in getting back to me and scheduling a time to get out and test the water. His son Derrick showed up a couple days later and walked me through every single step of what he was testing and what effect this had on the water. They sent me a quote the same day for the system and had me on the schedule for the following week to
