Watermain break prompts boil water advisory for 3 Calgary communities

Alberta Health Services has ordered Calgary to issue a boil water advisory for three communities, effective immediately.

The advisory applies to Silverado, Yorkville and Belmont until further notice.

A watermain break Thursday afternoon disrupted water supply to a large portion of those communities at the far southwest corner of the city, and while water has been restored to most homes, the city says the advisory has been issued out of an abundance of caution.

All residents and businesses within the affected area are instructed to bring all tap water to a rolling boil for one full minute prior to any consumption, including brushing teeth, making ice, cleaning raw foods, drinking and making baby formula.

Water used for bathing or for laundry does not need to be boiled.

The city says it is working closely with the Alberta Environment and Protected Areas and Alberta Health Services to resolve the water quality concerns.
