City crews continue search for source of 'catastrophic' water main break

Source of break could take days to identify, mayor says

In this case, the affected water main is called the Bearspaw South Feeder Main, which Mackay called the "most critical" in Calgary's water system as it moves water to east and south parts of the city, away from the city's largest water treatment plant in north Calgary.

"If we are being very, very optimistic, and they can remove the water from the site and actually get in there and have a look at what's going on, it is possible that within the next day to two days they can identify the problem," Gondek said.
