What is a Water Managed Site?

A Water Managed Site is a property with an in-ground irrigation system certified by The City of Calgary for water efficiency.

Properties must have an in-ground irrigation system that uses either climatic or historical weather data to set watering schedules and must complete a system audit conducted by a Certified Landscape Irrigation Auditor.

How can my site become a Water Managed Site?

All residential, commercial, industrial and institutional customers may apply to become a Water Managed Site.

Steps to become a water managed site:

Step 1: Print and complete a Water Managed Site application.

Step 2: Contact a Certified Landscape Irrigation Auditor. Certified Landscape Irrigation Auditors (CLIA) are certified by the Irrigation Association. A list of local, certified auditors can be found on the Irrigation Association - Certification Directory.

Step 3: Have your Certified Landscape Irrigation Auditor visit your property to conduct the audit. The auditor will produce an audit report and as-built drawings or schematics of your irrigation system.

The cost of this work will be unique to each site, please discuss this with your Certified Landscape Irrigation Auditor (deferred during restrictions).

Step 4: Complete and submit these forms:

  • Water Managed Site Application Form
  • Certified Landscape Irrigation Auditor's report (deferred during restrictions)
  • In-ground sprinkler system as-built drawings or schematics
  • Send to: Water Managed Sites
    City of Calgary, Citizen Programs Team
    #433 P.O. Box 2100, Station M
    Calgary, AB T2P 2M5

Step 5: Once the application has been received, The City of Calgary will contact you within 10 business days to acknowledge that the application has been received, and is undergoing the review process.

Step 6: When the review is complete, The City of Calgary will notify the applicant of the status of the Water Managed Sites application, and will provide notification in writing on Tier 1 or Tier 2 designation (if applicable).

Frequently asked questions

How will my property be identified as a Water Managed Site?

All certified Water Managed Sites will receive a letter from The City of Calgary identifying their property as a registered Water Managed Site.

During watering restrictions, Bylaw Services will be provided with a list of Water Managed Sites.

Does a Water Managed Site ever have to be re-certified?
