City of Calgary presented updates on the Preferred Watering Days initiative and Water Managed Sites Program. These proactive measures aim to help manage the City's water system load while critical infrastructure repairs and upgrades continue.
While essential repairs to the feeder main have been completed, the City is not yet operating the line at full capacity. Until major infrastructure projects are finalized, there remains an increased risk that Stage 1 Outdoor Water Restrictions could be called if water demand exceeds system capacity.
As we enter the spring and summer seasons — our busiest period for irrigation — it’s vital that our industry leads by example. By working together, we can help reduce system strain and minimize the likelihood of formal restrictions being imposed.
Why Water Conservation Matters Now, Reducing watering especially important when:
- Water treatment or distribution infrastructure is under repair or upgrade;
- Hot weather drives high demand that strains water treatment capacity;
- River levels are lower than normal due to drought;
- River water quality fluctuates.
Action Requested: Adopt Preferred Watering Days
To assist the City and protect the health of our landscapes, all irrigation professionals are asked to configure systems to follow the City’s Preferred Watering Days.
This is not a bylaw change — it is a voluntary industry effort to help balance demand and protect our ability to operate without restrictions.
Preferred Watering Days:
- Odd-Numbered Addresses: Wednesday, Friday, Sunday
- Even-Numbered Addresses: Tuesday, Thursday, Saturday
By adjusting irrigation schedules accordingly during spring system start-ups, we can help the City's reservoirs replenish adequately during periods of peak use.
About Water Managed Sites (WMS)
A Water Managed Site (WMS) designation certifies that an irrigation system can adjust watering based on actual site needs — either by weather conditions or soil moisture levels — to maintain landscape health efficiently.
Certified WMS sites are permitted greater flexibility under Stage 1 Outdoor Water Restrictions (Schedule E).
Becoming a WMS ensures:
- Healthier landscapes during periods of water shortage.
- Protection of client properties.
- Continued leadership by our industry in responsible water use.
