Water and Light
Your trusted source of water and electricity for over 100 years.
Our mission is to deliver reliable, safe and cost effective water and electric service to meet our citizen owners' needs while providing exceptional customer service and environmental stewardship.
Columbia Water & Light was formed by voter approval in 1904. Since that time, the utility has been furnishing Columbians with low cost, reliable electricity and high quality water. Every customer is an owner of the utility and has a say in how the utility is run. Operational recommendations are made to the Council by the Water and Light Advisory Board. Final decisions concerning Columbia Water & Light are made by the City Council. The utility is run as a department of the City of Columbia. Contributions are made to city government in the form of a gross receipts tax, property tax and to the general fund for city services.
