The City of Calgary has issued a boil water advisory affecting roughly 500 residences and businesses in several southwest communities due to a broken service line and water main “disruption” on Friday morning.

The advisory applies to the community of Spruce Cliff and parts of Wildwood and Rosscarrock, and is expected to remain in place for at least three days.

In a news release Friday, the city said a water service line broke on a private property earlier in the day.

“In the course of shutting off water to the affected property, there was a disruption to the water main supplying drinking water to the wider area,” the city said.

Water service was expected to be restored Friday afternoon, however, Alberta Health Services ordered the boil water advisory as a “precautionary measure,” the city said.

The advisory is not related to the Bearspaw South feeder main, the release states.

Residences and businesses within the affected area are being advised to bring all tap water to a rolling boil for at least one minute before using it for drinking, brushing teeth, cleaning raw foods or making ice.

“Residents and businesses may instead choose to purchase bottled water for consumption for the duration of this advisory,” the City said.

The city says water wagons are being provided in the area, with locations listed on the city’s website.

The advisory will remain in effect until further notice, but is expected to last at least until Monday.

“We anticipate this order being in place for a minimum of three days to allow time to flush the water main and complete the necessary water quality testing,” the City said.
