If water usage in Calgary continues at its current rate, the city could be forced to bring in mandatory indoor water restrictions, the mayor said Friday, calling the situation urgent and catastrophic. The Bearspaw south water main, which is 11 kilometres long and as wide as two metres in parts, suffered a break on June 5 that temporarily left hundreds of homes and businesses in the city's northwest without water. Water usage has been increasing every day since Saturday, three days after the pipe broke. If our water usage continues to trend up and our water can't keep up, the taps will run dry at some point, Gondek said. On Thursday, Francois Bouchart, the director of capital priorities and investment with the city's infrastructure services department, said progress has been made on fixing the water main.
