In just two days, the number of properties in Guelph dealing with water issues has more than doubled.

City officials said Wednesday that nearly 400 customers are dealing with the effects of frozen water lines.

As of Monday, that number stood at 146.

“People who need water for medical conditions and other critical care customers are our first priority and all of those cases will be addressed by the end of today,” Peter Busatto, the city’s general manager of water services, said in a news release.

After that, city crews will work first on the properties that have been without water the longest – especially businesses.

“We’re prioritizing businesses because we don’t want people going without pay because a business had to suspend operations,” Busatto said.

Already, 42 temporary water lines have been installed across Guelph. By Sunday night, city officials expect that total to rise by at least 100.

As of Wednesday, temporary lines were being installed for customers who had contacted the city on or before Feb. 26.

City officials say more pipes are expected to freeze over the remainder of the week, as temperatures remain below freezing.
