Even city buildings were not immune to the dangers of frozen pipes on Friday, after temperatures dipped to lows not seen on the date in 119 years.

The Visitor Center at 524 N. Main St. had to close for most of the day after a pipe in a sprinkler room attached to the building ruptured, sending water onto the sidewalk — where it promptly froze and created a dangerous situation for anyone trying to enter the building.

City spokeswoman Diana Klink said the sprinkler room is equipped with a permanent heater, but the heater malfunctioned at the exact wrong time.

“We had taken all reasonable steps to prevent such an occurrence,” she wrote in an email. There are no faucets to drip in the sprinkler room to keep the water running, she added.

Throughout the city on Friday, Public Utilities crews responded to about 30 calls for emergency cut-offs after private pipes burst after freezing, Klink said. That brings the total since Sunday to 125.

On Thursday, customers in the 300 block of Spruce Street and the 900 block of East Riverview Drive were out of water for most of the day while the city made repairs to public pipes, which Public Utilities Director Al Moor said may have been at least partially caused by the low temperature.

The low on Saturday, even during the night, is predicted to be 44 degrees, so dripping faucets is not necessary. However, Moor said, there is “potential for additional issues” as the thaw happens, and additional staff have been assigned.

The reprieve won’t last long, though — cold weather is predicted again for next week.
