Our Story

Cascadian Water was founded in 1994 by Gabe and Diane Ergler in their home in Snohomish, WA. Like many homeowners in the region, they faced serious water quality challenges. Their private, hand-dug well was full of tannins and other contaminants, making their home’s water unhealthy. This challenge led to a journey that would not only improve their own water but transform the way thousands of people experience clean, high-quality water in their homes.

With curiosity and determination, Gabe explored innovative water treatment solutions, eventually founding O3 Water Systems—which later became Cascadian Water. Today, we continue that legacy, providing simple, effective, and innovative water treatment solutions that empower distributors, plumbers, and homeowners to solve their water challenges.
