A water tower fire on Madison’s west side has wiped out WiMAX broadband service for at least 150 fixed wireless broadband customers, leaving them cut off for so long, provider TDS Telecom is canceling their service and assisting customers in switching providers.

A Madison utility manager said workers Friday were preparing to paint the 100,000-gallon tower in the 2700 block of Prairie Road when insulation around communications cables caught fire.  Smoke was visible from the empty water tower for miles, and several nearby homes had to be evacuated because of fears of a potential collapse.

City engineers have since deemed the tower safe, but the real impact will be several months of interrupted broadband and cell service from several area providers who depended on the tower as an antenna site.  The tower was particularly crucial to TDS Telecom, which depended on its strategic location to deliver its wireless broadband service in western Madison.  It will take several months to restore service.

“Based on our discussions with the City, we anticipate it could take a very long time to repair the damaged tower,” states DeAnne Boegli, TDS National Public Relations Manager. “Since this is the only viable tower location TDS can use to serve these homes, and because temporary solutions are not available, our customer’s best option is to select another facilities-based communications provider.”

TDS will assist all 147 impacted customers in changing their service without penalty and remove the equipment from customer homes at their request and convenience. The company is also providing the customers a month’s service credit.

“Unfortunately, this accident has left us with no reliable or timely restoration options. TDS understands communications services are critical to our customers and we want to get them transitioned as quickly as possible, even though it means they must select another provider,” said Boegli.

Affected cell phone companies are trying to establish temporary cell tower sites to improve service in the area while repairs get underway.
