Flooded streets, stranded motorists, boil water advisories and directions to conserve water — Calgarians saw another catastrophic water main break late last month, the second in less than two years.

Restrictions have now been lifted, but Calgary’s mayor says it’s a wake-up call, alerting the city that repairs to the aging infrastructure aren't adequate, and it’s time for a long-term solution.

But underneath the streets of Winnipeg, there are many pipes of the same age and material as the one that broke in Calgary. So should we be worried? CBC’s Cameron MacLean explains how vulnerable our water system really is.
