Calgary water remains safe to drink, monitoring in place

Media statement

On Saturday evening The City of Calgary was advised that a sewer main line break in Cochrane had caused an overland sewage discharge affecting the Bow River upstream of Calgary.  

We activated our Water Services Response team and have been carefully monitoring the situation and working with the Town of Cochrane.  

As of Sunday morning, we have seen no change in water quality at the Bearspaw Water Treatment Plant. Calgary’s water remains safe to drink.  

As a precaution, we are asking Calgarians to stay out of the Bow River for the remainder of Sunday. We are conducting extra water quality sampling on the Bow and will provide updates as they are available.
