‚ÄčNatural causes

Extreme temperature fluctuations in the winter and spring are a leading cause of water outages. As the ground freezes and thaws several times, it can shift the earth and cause water mains to break.

Emergency interruptions

Occasionally, we have to shut off water to areas during emergencies or to conduct certain repair work that can't be safely handled any other way.

Corrosion

Many of the pipes used in water distribution are made from cast iron, which is susceptible to corrosion. Corrosion weakens the pipes and leads them to break. To help combat this issue, we're continuously replacing these cast iron water mains with Polyvinyl Chloride (PVC), which has significantly reduced the number of main breaks. Read more about our Water Main Renewal Program.

Unplanned interruption

Water outages can occur when underground pipes are accidentally hit and damaged. It's important to confirm where water lines are before starting to dig. Visit Alberta One-Call's Click Before You Dig. ‚Äč

Planned interruptions

We'll occasionally schedule planned water interruptions, so we can maintain the neighbourhood water supply system. This involves the replacement of cast iron water mains with PVC to help combat corrosion damage.
