History of CTW Corporation

Our founder Bill Cummens worked for years at a Water Well Contractor but after seeing the need for a customer service based contracting service, he decided to go all-in an start up his own business in 1972. Bill grew up in Clara City, Minnesota and was childhood friends with the Thein brothers. Bill got his first drink of water contracting with the Theins who trace their history back to 1893. Thein Well Company helped provide initial financial assistance to Bill which is where CTW (Cummens-Theins Wells) Corporation got its name.

Bill started off with just a small pump hoist and a couple pipe wrenches working out of his garage but quickly gained customers through his focus on customer service. Bill’s son, Tim followed in his father’s footsteps graduating from the University of Minnesota- Twin Cities with a degree in civil engineering. He began working for the company in 1977 right out of high school.

Over the next few decades, CTW continued to grow throughout Wisconsin and Illinois. As one of the few well contracting companies with Professional Engineers on staff, CTW differentiated themselves by providing that same customer service with an analytical approach to solving the problems rather than treating the symptoms.

“There is no job too small or too large that we cannot solve.”

We pride ourselves on our history, we’re the longest continually operated water well and pump contractor in the state and many of our current customers have been with us since we started in the early 70’s. We focus on serving the municipal, commercial, agricultural, aggregate, and golf course throughout Wisconsin. At times, our legendary customer service and expertise has called us throughout the country – from water system controls in California to installation of a control system for one of the busiest airports in North America.
