The Cascadian Brand and Products

As he continued to develop his industry expertise, Gabe also began developing his own products by combining the his experience and the best components available and when nothing is available he manufactures it. A personal drive to make sure every customers’ water problem can be solved has led him to develop a line of specialized, proprietary products under the Cascadian® brand. The ever-evolving assortment of Cascadian Water products meet many different residential, commercial and industrial customer needs.

First, he created an improved version of the traditional systems that use tanks, media, control values and often require salt to regenerate. Unlike traditional water treatment solutions, however, Cascadian® fully-automatic products are very specialized. They are designed to do only one or two things and do them very well. This “riffle” approach to treatment greatly improves the success rate and leads to happy customers. Cascadian’s fully-automatic products include OxiTRAP®, SuperTRAP®, SuperTRAP®-UF, ArsenicTRAP™, FluorideTRAP™, OrganicTRAP™ and Pinnacle™.

Most recently Gabe and his team have developed an entirely new way to treat water that is simple, efficient, effective and environmentally-friendly. The ICS (Integrated Cartridge Solutions) line of products from Cascadian® produce high quality water without salt, harsh chemicals, waste water or power. ICS treatment systems are available in a small package requiring simple annual maintenance. Gabe continues to further specialize the ICS products, recently introducing a new cartridge-based water treatment solutions for problematic hydrogen sulfide, aka rotten egg odor, in residential drinking water.

As the water treatment industry continues to grow and change, Gabe will continue to ensure that every last customer can find a clear path to clean water.
