GWT History

Global Water Technology, Inc. was founded in 1990 by Maria E. Villarreal-Byerley to meet a growing demand in the Chicago area for personalized, affordable, and reliable water and waste water treatment services. Over the next ten years, with the goal to establish an honest, reputable company which any management team could be proud to partner with, GWT was quickly able to build a strong reputation in the commercial, residential, industrial, hotel, and healthcare industries in the downtown area. In the early 2000’s GWT’s reputation for superior service and creating cost effective, resource saving, and equipment preserving strategies allowed it to expand into other geographic areas beyond the downtown area and Chicago suburbs. Today, Global Water Technology, Inc. is one of Chicago’s leaders in water treatment service and continues to expand across state lines.
