January is typically the busiest month for water main breaks in Calgary, but this week more than usual have occurred. On Thursday, the city's website showed 12 broken water mains, seven of which ruptured Wednesday. "That's abnormal," said Lee Dupras, leader of repair and maintenance for drinking water distribution at the City of Calgary. "I have not seen that many in one day come in since I've been in this [department] of the city."
