UPDATE: The water main break on Lookout Mountain is fixed and water service should be restored in about an hour, according to a Tennessee American Water spokeswoman.
"Right now they're flushing out the lines to make sure all the air is out," spokeswoman Daphne Kirksey said just after noon today. Crews will also install a metal plate over the hole where the work was done until the site can be redressed.
ORIGINAL STORY: Tennessee American Water customers on Lookout Mountain in the area of Forest Avenue North and Watson Street will be without water till this afternoon following a water main break early this morning, officials said.
Daphne Kirksey, spokeswoman for Tennessee American, said the break happened sometime between 5:15 and 5:30 a.m., allowing water to spill downhill to Scenic Highway with bitter cold temps turning some of it to ice.
"It's been running down ot Scenic Highway so we had a salt truck there and police were on site. We're in the process of shutting the water off so that'll stop it from running," Kirksey said around 8:30 a.m. Thursday.
"Customers in the affected area will be without water until at least lunchtime while we make the repair," she said.
Crews first had to mark locations of all underground utilities so the repairs can be made with damaging adjacent lines, she said. Repair work got underway by about 7:30 a.m.
It's not yet known what caused the break.
"Cold weather can certainly be a factor," Kirksey said noting how unseasonably warm January 2018 was compared with this year.
When the repairs are made and service is restored customers should turn on a cold water tap, in a bathtub or other larger fixture, and allow the air and any discolored water the bleed out of the lines for a few minutes, Kirksey said.
"If it doesn't clear, they can call always our call our customer center and we can follow up with them," she said.
