A Rich Tradition of Reliability

We were founded in 1890, the same year Idaho was granted statehood. For more than a century, we've been growing with our expanding community.

The first water supply in Boise ran from Hulls Gulch, down Eighth Street, to the Eastman Hotel. It consisted of two artesian wells, two and one half miles of water mains, one reservoir, and one service level.

Today we operate 85 wells, 36 reservoirs, two treatment plants, 1,163 miles of water mains and 7 pressure levels.

Artesian Water merged with Boise Waterworks in 1891 to form the Artesian Hot and Cold Water Company. The company used thermal water from hot springs to heat downtown buildings, including the historic Natatorium.

In 1913, with the advent of regulation by the Idaho Public Utilities Commission, the hot and cold water divisions of the company were separated. Boise Water provided drinking water while its sister company, Natatorium Water, supplied hot water.

The Boise Water Company was officially incorporated in 1928 and was acquired 18 years later by General Waterworks Corporation. In 1994, General Waterworks Corporation merged with United Water which is now one of the largest water services company in the nation. The following year, Boise Water changed its name to United Water Idaho to reflect its relationship with its parent company,

We are proud to have played an important role in the growth and development of our franchise area for more than a century.

And we look forward to providing you with the highest quality water and service for another 100 years.
