Specializing in municipal water and wastewater projects, Simpson Industrial Services provides construction and maintenance services including water treatment plants, distribution, waste water processing and lift stations.

Headquartered in Lethbridge, Alberta, Simpson Industrial Services roots can be traced back to the founding of Simpson Plumbing in 1983 by Bill Simpson.  Prior to this Bill Simpson was a partner in Can West Mechanical who focused on the municipal water & wastewater industry.  A good portion of the water treatment plants, pump stations, lift stations, & sewage treatment plants in Southern Alberta and BC were completed by Can West during the 1970’s and 1980’s. 

Bill along with his son Roger Simpson lead Simpson Plumbing back to the municipal sector and completed many different water / wastewater projects.  Jim Simpson rejoined the Simpson Team in 2013 and the Simpson Industrial Services division was created in the company. In 2015, Simpson Industrial Services Ltd became a separate company.
