Facts about our watering schedule

Why was this odd and even system chosen?
The odd/even system allows us to balance the demand for water throughout the week. There are also an equal number of watering days in the month for each customer.

What happens on Fridays?
Not permitting watering on Fridays gives the reservoirs a chance to replenish in preparation for the weekend, which is when the City experiences its highest demand.

Can I still water my flowers?
Gardens, trees, shrubs and flowers can be hand watered any day in a level one or two but not during a level three water restriction.

Can I fill up a kiddie pool or let my kids run through the sprinkler?
Yes, your kids can run through the sprinkler and you can fill fountains and other decorative features on any day during level one. Neither are allowed during a level two or three water restriction.

I just planted new sod, can I water it?
You can water new grass plantings (sod or seed) every day with a water use exception permit.

I’m not home during the designated watering times, what should I do?
We’d recommend getting a water timer to put on your hose. You can get them at most hardware stores.

Won’t my grass die?
Studies have shown that watering less creates stronger grass but some other tips for great grass are:

  • Only water when you need to. An established lawn only requires about one inch of water a week.
    TIP: place a Frisbee® upside down on the lawn and only water until it’s full.
  • Leave grass 3” long to prevent scorching and water evaporation
  • Grass-cycle – mulching leaves your grass clippings on the lawn, providing extra nutrients and helps to retain moisture.

I pay for my water, why can’t I just water whenever I want?
Water is a finite resource that needs to be protected. The Bow Glacier that feeds the Bow and Elbow Rivers has experienced significant depletion over the past few decades. The City gets our water from Calgary, who sources it from these rivers. Watering during the scheduled times (early in the morning or late at night) will reduce evaporation and allow water to soak into the soil and reach grass and plant roots.

Will my water rates go down because of this?
Your fixed service rate covers the water service to your home and maintenance of water service infrastructure so it doesn’t go down based on consumption. 

What other municipalities have these types of restrictions?
Okotoks and Vancouver have a seasonal watering schedule. Nanton and Cochrane have year-round watering schedules. Nanton and Okotoks’ are also based on the even/odd system.

How will this be enforced?
When the watering schedule was introduced in 2019 the focus was on educating residents about water conservation and the new Bylaw. Now, Municipal Enforcement officers will investigate situations based on complaints that are called in.

Why does the City water when it’s raining?
There are a few sites in Airdrie where stormwater is used to irrigate greenspaces, separate from the potable water irrigation system. These sites are not linked to rain sensors and may be irrigated during or immediately after rain. This can be an effective measure to prevent salt present in stormwater from building up in the soil to protect long-term soil quality. This may also occur if the amount of rain isn’t enough to trip the automatic settings in the park's smart irrigation system.

I’ve seen fire hydrants flushing lots of water before. Why does the City do that?
Water mains are flushed prior to restoring water services to residents. This process flushes sediment from the lines and is required by the Province. All publicly owned hydrants are flushed and tested in the spring by the Airdrie Fire Department (AFD) to meet the National Fire Protection Act standard.
