The Onalaska Water Supply was incorporated as a non-profit corporation in 1966. In 2000, the articles of incorporation were amended to include the natural gas system which was purchased at that time from the City of Onalaska.

Our goal has always been to supply our members with a clean, safe water supply at the most reasonable rates possible.

The water department operates under the regulatory auspices of the Texas Commission on Environmental Quality. The natural gas system is regulated by the Texas Railroad Commission.
