Boil Water Advisory issued for three Calgary communities

Alberta Health Services (AHS) has ordered The City of Calgary to issue a Boil Water Advisory, effective immediately. This Boil Water Advisory applies to the communities of Silverado, Yorkville and Belmont.

In the afternoon of Thursday, June 1, a watermain break disrupted water supply to a large portion of these communities. While water is now restored to most homes, the Boil Water Advisory is in place as a precautionary measure.

All residents and businesses within the affected area are advised to bring all tap water to a rolling boil for one full minute prior to any consumption, including: 

  • Drinking
  • Brushing teeth
  • Cleaning raw foods
  • Preparing infant formula or juices
  • Making ice, etc.

Water used for bathing or for laundering of clothing does not need to be boiled.

Residents may instead choose to purchase bottled water for consumption for the duration of this advisory. 

This advisory will remain in effect until further notice.

The City of Calgary is working closely with the Alberta Environment and Protected Areas and Alberta Health Services to resolve the water quality concerns.

“Our crews worked quickly to restore water after a main break on Thursday afternoon,” said Chris Huston, Acting Director or Water Services. “We were able to restore water to the affected communities early Friday morning. The Boil Water Advisory has been issued out of an abundance of caution.”
