Water outages and main breaks

We know you rely on us to provide reliable access to clean and safe water. When outages happen, we work to notify you and restore service as quickly as possible.

Water main breaks are unpredictable and can happen for a variety of reasons:

  • The age, material and condition of the pipes
  • Condition of the soil
  • Temperature of the ground and water
  • Pressure changes

If you see a water main break (water coming up through grass, road or sidewalk), contact 311 and a Water Services crew will be dispatched.

Under normal circumstances, water main breaks are repaired and water is back on within 48 hours. We prioritize breaks based on factors such as the risk of property damage, impact to critical facilities (like hospitals or schools) and number of customers that are out of water.

If your water is off and you have not been notified yet, it may be due to a short-term break in your area, repairs within your building, a break outside regular hours, or a frozen water line.

To prevent the spread of COVID-19 when using a water wagon, follow these steps:

  • Keep 2 metres or 6 feet between yourself and others.
  • Wash your hands before and after you take water. Use hand sanitizer if soap and water is not available.
  • Do not use a water wagon if you are self-isolating. Ask a friend, member or neighbour to get water for you; if this is not possible call 311.

Current main breaks and water outages

The latest water main break information will be displayed here once the break is confirmed by the City and at least one home or business is affected by a water service disruption. Please note that not all water service disruptions are due to a water main break.

Frequently Asked Questions

How can I get water while the main is being fixed?

The two most common solutions are:

  • A water wagon - a portable tank of drinking water that provides emergency supply to customers. It is placed in a central location to provide customer water access to water during longer outages.
  • Temporary water - we may also provide water to property owners after a water main break through a hose attached to a fire hydrant or a neighbour's home.

For shorter outages, and to support you while water wagons or temporary supplies are set up, we recommend keeping a small emergency supply of water on hand.

You can continue to use the toilet during interruptions by pouring stored water into your toilet bowl to empty its contents.

During the temporary closure of City facilities, we are unable to provide facility passes. While we work hard to restore water service as quickly as possible, we recommend that Calgarians use water from on-site water wagons to take baths. We apologize for the inconvenience and thank Calgarians for their patience.

How is a water main fixed?

  1. A crew is dispatched to determine the location, impact and severity of the break
  2. Crews reduce and shutoff water flow by closing nearby water valves
  3. Crews identify alternative sources for temporary customer water
  4. Crews excavate and repair the watermain
  5. Service is restored after the pipe is flushed and water quality is tested
  6. The road, lane, sidewalk or lawn is repaired. This may take time depending on the season, weather, difficulty of the location and size of the break. If there are damages from the water main repair, we will arrange for rehabilitation or repair. Learn more at Water Service Construction Property Rehab.

What should I do once my water is turned back on?

We test for quality before water is restored. If your water is discoloured, it is still safe to drink. To ensure the issue is resolved:

  • Run your bathtub tap on cold for 30 minutes until water clears. Then run other cold water taps for five minutes or until clear.
  • Wash tap aerators or screens in hot, soapy water, and disinfect them for 10 minutes in a solution of one part bleach to nine parts water.
  • Disinfect water filters to manufacturer's recommendations.

If water does not clear after running the taps, contact 311.
