Boil water advisory in effect for three Calgary communities

Three southwest Calgary communities are under a boil water advisory due to a watermain break Thursday afternoon at a nearby construction site.

Three southwest Calgary communities are under a boil water advisory due to a watermain break Thursday afternoon at a nearby construction site.

It appears as though an excavator ruptured a pipe, resulting in a large pool of water flooding a portion of the site.

Alberta Health Services (AHS) says residents in Silverado, Yorkville, and Belmont are advised to bring tap water to a rolling boil for at least one minute before consumption.

Water used for bathing or washing clothes does not need to be boiled, but residents in the impacted areas should bring tap water to a boil before brushing their teeth, cleaning raw foods, preparing any type of juice or other drinks, and making ice.

One CTV News viewer says blackened water was coming from their taps late Thursday night.

According to the city's website, 1,000 homes and 100 businesses have been impacted by service interruptions.

Fatima Pacon, who lives in the area, says she noticed something wrong with her water at around 4 p.m. on Thursday.
