Update July 18: Critical water main break affecting city-wide water usage

via City of Calgary

Some sprinkler use and hose watering now permitted as City moves to Stage 2 Outdoor Water Restrictions

Today, we achieved another major milestone in the recovery from the Bearspaw South Feeder Main break, by moving from Stage 3 to Stage 2 Outdoor Water Restrictions. This change allows for more outdoor water use, including watering with a hose and spray nozzle, and some sprinkler use according to set days and times.

On Monday, we began increasing water flow through the feeder main to 70% of its maximum. This was done cautiously to minimize pressure spikes that could cause additional stress on the pipe walls. So far, the pipe is performing well and this has given us confidence that the system is ready to manage higher water demand.

 

Effective immediately, the following activities are allowed under Stage 2 Outdoor Water Restrictions:

 

1. Some sprinkler use on certain days and times:
   1. Water with a sprinkler for up to one hour per week on a set schedule
   2. Sprinkler schedule is based on address
   3. House numbers ending with an even number can use a sprinkler Wednesday or Saturday
   4. House numbers ending with an odd number can use a sprinkler Thursday or Sunday
2. Sprinkler use is allowed 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:

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

The following is not allowed at any time:

1. Outdoor washing of cars, windows, exterior building surfaces, sidewalks, driveways or walkways
2. 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.

Next steps

We will continue to monitor the pipe and water demand on Friday and through the weekend. If things remain stable, we could move to Stage 1 Outdoor Watering Restrictions as early as Monday, July 22.
