Commitment to Safety
Global Water Technology, Inc. was founded in 1990 to meet a growing demand in the industry for personalized, affordable, and reliable water treatment services. The primary goal was to establish an honest and reputable company that management teams would be proud to partner with. As a result GWT built a strong reputation in the commercial, residential, industrial, hotel, and healthcare markets throughout the Midwestern United States.
GWT’s reputation for superior service and creating cost effective, resource saving, and equipment preserving strategies has allowed for continued growth and expansion throughout the United States and across a wide variety of industries.
Today, Global Water Technology, Inc. is one of the industry’s leaders in water and waste treatment.
Michael is the second generation to lead Global Water Technology, Inc. The company was founded by his mother, Maria Byerley in 1990. Michael joined GWT in 2009 as an intern and was hired full time following his graduation from Northwestern University. During his first few years, Michael worked closely with GWT’s sales and service teams to develop his understanding of the technical side of GWT’s products and services, gain perspective of the water treatment industry, and help create a progressive marketing and growth campaign.
GWT tries to find ways to give back to and support the community. We have found that the most successful ways to give back begins with active participation in the community itself. With our participation, we hope to aid in the sustained growth and success of community organizations, business associations, youth programs, and educational institutions.

Causes GWT Directly Supports:
Maria E. Villarreal-Byerley
Founder, Past President
Global Water Technology, Inc. (GWT) was founded in 1990 by Maria E. Villarreal-Byerley. Previously, Maria worked with her husband, William Byerley, to establish Environmental Mechanical Services (EMS), one of Chicago’s finest HVAC service companies. In the early 90’s EMS merged with Hill Mechanical Services, allowing her the opportunity to begin her own venture. It was while at EMS that she perceived a demand for a new type of company in the water treatment industry. With a handful of experienced industry experts from established companies, she founded GWT on the principles of service, honesty, and partnership. These founding principles have laid a strong foundation for the growth and success of the modern organization.
In 2005, GWT expanded into the facility operations field, establishing its Engineering Services division.
Maria’s son, Michael Byerley, joined the organization in a Business Development role after his graduation from Northwestern University in 2011. His task was organizational modernization and expansion through acquisition, diversification, and development of a modern sales infrastructure. Michel was promoted to Vice President in 2013.
Notably in 2015 GWT acquired a Chicago-based firm, Midwest Products & Consultants, which focused on waste water and other industrial process water treatment consulting services. GWT continued its acquisition mission through the acquisition of Superior Water Management, another Illinois based firm in August of 2016.
In August 2015 Michael Byerley was promoted to President of GWT and in August of 2016 Maria retired from the organization.
In July 2017, GWT continued its growth initiative by agreeing to assume PCS Industries Water Treatment as HP Products (acquired PCS in 2015) moved out of the water treatment service field.
In February 2019, GWT Acquired Lakeland Chemical Specialties, Inc. (LCS). The company was founded in 1991 and is a member of the Association of Water Technologies (AWT), specializing in water treatment chemistry and services for cooling towers, steam boilers, closed loops, and potable water systems. GWT merged all of its existing business in Wisconsin under a new division called Lakeland Chemical Specialties a Division of Global Water Technology. GWT retained Lakeland’s existing leadership, technical and administrative staff, organizational infrastructure, and warehousing in Menomonee Falls, WI for the long-term future. By virtue of this move, GWT expanded its Midwestern footprint by over 350 additional customers serviced at over 500 physical locations throughout Northern, IL and the state of Wisconsin.
Year to year, GWT achieves consistent double digit growth through customer retention, employee retention, and its sustainable national expansion strategy.
