Mayor Gondek update on critical water main break July 22nd, 2024

Since we began reintroducing the feeder main into service, we've been carefully monitoring its performance and moving cautiously to make sure our water supply can meet demand at each step of the way.

This cautious approach proved beneficial as last night, we began experiencing some issues at both the Glenmore and Bearspaw Water Treatment Plants, including pumps at water intakes.

We believe these issues are related to the current heat, and while they are not major, they will require investigation and maintenance. While the maintenance is completed it may impact the amount of water we are able to supply. In addition, with hotter than anticipated temperatures this week, we expect water demand to remain high.

While we had hoped to be able to move to Stage 1 Outdoor Water Restrictions today, we have decided to remain at Stage 2 for now.

Our modeling indicates that we can still meet Stage 2 demand but may not be able to meet the increased demand if we move to Stage 1, which allows for two hours of sprinkler use each week instead of one.

We understand the eagerness to ease Outdoor Water Restrictions, but it is important that we continue to move cautiously to make sure we have enough supply. We will reassess whether we are ready to lower Outdoor Water Restrictions by mid-week once we have more information.

Stage 2 Outdoor Water Restrictions

Yesterday, Calgary's water use was 648 million litres, which aligns with our forecasts under Stage 2 Outdoor Water Restrictions and the current heatwave.

As a reminder, Stage 2 Outdoor Water Restrictions allow for use of a sprinkler for up to one hour a week, on a set schedule among other things.

House numbers ending with an even number can use a sprinkler Wednesday or Saturday
House numbers ending with an odd number can use a sprinkler Thursday or Sunday
Sprinkler use is recommended in the morning or later in the evening to avoid evaporation during the hottest part of the day.

The following is allowed at any time:

Watering with a hose that has a trigger spray nozzle or drip irrigation
Hand watering using a watering can or other container
Watering new grass with a sprinkler or irrigation system
Water use for pesticide or fertilizer application

The following is not allowed at any time:

Outdoor washing of cars, windows, exterior building surfaces, sidewalks, driveways or walkways. Note: manual window washing by certified companies is allowed, other window washing is not.
Filling fountains or other decorative features, except for bird baths

These restrictions continue to apply to all customers who use City water. This includes all Calgary residences, businesses and City operations.

Bowness water main break repaired

Yesterday afternoon repairs were completed on the water main break in the 5100 block of Bowness Road N.W. and water has now been restored to affected businesses and residents.

The incident was not directly related to the Bearspaw South Feeder Main and was on a smaller 10-inch cast iron pipe nearby.

The road has partially reopened as of last night and is expected to fully reopen by tomorrow. Please continue to drive carefully in the area and obey detour signs.

Next steps

We are committed to keeping you updated on our progress and any potential setbacks as we work to restore full water service to Calgarians. Thank you for your continued support and patience.
