Year Founded:

Many controls customers knew of Bill and his expertise in water treatment and expressed a desire that he begin a new residential and commercial water treatment manufacturing company. Shortly after, CSI Water Treatment was born. Bill knew that just assembling equipment would not be enough. An experienced technical support staff, along with innovative new products, were the key to success in the past and would also be in the future.

Bill was able to acquire the talents of two water treatment professionals that had helped build Water Soft Inc. into the successful company it once was. Duane Baney and Russ Norris, with a combined experience of 30+ years in water treatment manufacturing, joined CSI Water Treatment in September of 1995.

Soon thereafter, CSI introduced an innovation in air injection technology - the REACTR™. The REACTR™ utilizes a manifold that combines air induction with free air release for the oxidation of Iron, Manganese and Sulfur Gas.

An option for the REACTR™ called the OXYCLEAN™ has been developed to introduce chlorine automatically during the backwash cycle for cleaning of the system.

The REACTR™ and OXYCLEAN™ technology has evolved into a revolutionary product for almost unlimited levels of iron and sulfur gas reduction. The HYDROXR™ combines aggressive aeration with the oxidation power of hydrogen peroxide.

To further our treatment capabilities for any type of water pumping system, CSI Water Treatment has developed REACTR VS™ and HYDROXR VS™ for constant pressure (variable speed) and jet type pumping systems.

To enhance a quality product line, the Signature Series™ control valve was introduced to the market in July of 2003. Combining advanced electronic technology with high flow rates and simple to use programming, this proprietary control valve adds uniqueness and functionality to all CSI Systems.

CSI Water Treatment has been actively involved in the commercial / industrial water treatment market and has carried over the REACTR™ technology into their full line of commercial products. Their forte has been specially engineered systems, combining their expertise in both controls and water treatment. CSI Water Treatment distributes its residential / commercial products through a network of wholesale distributors across the United States and into certain foreign markets as well.

They are dedicated to the improvement of water quality through innovative development of water treatment products, design engineering services and educational programs to provide the utmost in quality and support to their valued customers.
