CALGARY (660 NEWS) – The extreme weather warning has ended, and while it may feel like summer, that doesn’t mean we’re out of the woods.
In most of the province, the mercury hovered consistently around minus 30 last week without factoring in the windchill.
On Sunday, Environment Canada had Calgary sitting at one degree – that’s close to a 20-degree swing from Saturday – and a 30-degree swing from last Monday.
But as we put away our bigger jackets, the punishing effects of the deep freeze may still be lingering.
“Mid-day, there will be some calls as to some of these broken water lines,” said Calgary Fire Battalion Chief Stu Laird. “The ice plug starts to thaw and melt out.”
Laird added that once the water warms from the once frozen pipes, the stress causes them to split.
“The pipe will rupture, but it won’t flow because it gets an ice plug – then when it warms up again that ice plug will melt and that will start the water again, and that will alert the occupants either residential or commercial once the water starts flowing.”
Calgary Fire says dealing with broken pipes and water main breaks is par for the course when temperatures dip this low.
They are expecting more calls as the temperatures rise, but they’re prepared to deal with them.
“If you have a pipe burst in your home, you should shut off the water main valve immediately and contact 311 or a plumber,” said Laird.
According to the City of Calgary website, crews are working on seven different water main ruptures, the latest reported in Bowness.
