We have installed more than 2,400 individually designed water treatment systems across the United States and Canada. In 2017, Tonka Water was acquired by U.S. Water Services, Inc.

Our systems are used for groundwater, surface water, and wastewater applications. Our mission is to be universally recognized as the most innovative and flexible provider in the marketplace by focusing on safe, economical and environmentally sound solutions.

Tonka Water’s design and engineering capabilities have expanded over the years and led to projects of increasing sophistication.  Its systems are comprised of a broad line of treatment equipment, including solids contact basins, clarifiers, gravity filters, pressure filters, packaged treatment systems, aerators, ion exchange systems, VOC stripping towers, cross flow membranes and other system components. Processes include removal of arsenic, radium, total dissolved solids, disinfection byproduct precursors and color.

Our commitment to quality begins early by understanding our customers’ requirements and meeting their unique application needs.  Our quality management system is infused throughout our internal processes; from project planning, fabrication and inspection, to our experienced on-site field service professionals, all striving to meet our customers’ expectations with every project.
