Water Managed Sites
What is a Water Managed Site?
A Certified Water Managed Site (WMS) is a property with an in-ground irrigation system certified by The City of Calgary for water efficiency.
Certified WMS properties must have an in-ground irrigation system that uses weather data and/or on-site environmental sensors to control watering schedules. To maintain a WMS certification each site must produce an annual performance report that provides evidence that water use was reduced by 25% over the baseline of an irrigation timer scheduled to water every other day.
They must also have checks in place to ensure the safety of the water delivery system and measure use to prove performance efficiency.
Why become a Certified Water Managed Site?
This program supports the fact that not all landscapes are the same. Parks, sport fields, gardens and residential yards are all very different landscapes and require very different watering approaches to ensure they remain healthy. To do so, water availability for each of these must remain equitable in times of water shortage.
A certified WMS indicates that the irrigation system can respond to weather and/or soil moisture conditions at that site and apply the appropriate amount of water to the landscape to keep it healthy while avoiding water wastage.
A certified WMS is granted the opportunity to continue watering, as required by the site conditions, during watering schedules or at reduced rates during drought restrictions, as per Schedule E of the Water Utility Bylaw.
How can my site become a Water Managed Site?
Steps to become a water managed site:
Step 1: Site equipment verification
- A smart controller with remote operability and real-time weather data capabilities
- Weather station or a rain sensor or moisture sensor
- Leak/flow sensor
- Electronically controlled irrigation master valve
- A recently inspected and approved Cross Connection Control Device (RP/DCVA)
- Billing meter (multi-unit, residential, industrial, commercial, institutional sites only) or
- Volume totalizer (single family and duplex properties only)
Step 2: Book a Certified Landscape Irrigation Auditor
Contact a Certified Landscape Irrigation Auditor. Certified Landscape Irrigation Auditors are certified by the Irrigation Association. A list of local, certified auditors can be found on the Irrigation Association - Certification Directory.
The Certified Landscape Irrigation Auditor must maintain their certification status. A Certified Landscape Irrigation Auditor who does not maintain their certification or knowingly falsifies information in the applications/audits/irrigation system assessments or performance reports will be removed from The City’s list of Certified Landscape Irrigation Auditors.
Step 3: Certification application
Have your Certified Landscape Irrigation Auditor visit your property to conduct an inspection (start-up test) of your system and complete your certification application form on your behalf. Your Certified Landscape Irrigation Auditor must complete a fillable form and send it to watermanagedsites@calgary.ca
You will receive confirmation of the status of your application within 10 working days. Until that time, your site’s irrigation system must continue to operate normally, following all watering schedules or outdoor water restrictions enforced through the Water Utility Bylaw.
The size and type of site will determine which of the two tiers the site belongs to. A Tier 1 site will be greater than 0.5 hectares and/or be a park, playground, sports field or large green space. A Tier 2 site will be described as less than 0.5 hectares and commonly be a single family residential or small ICI space.
Sites which are certified will be immediately updated on a list of certified sites referenced by The City’s Community Standards team
Step 4: Irrigation System Audit/Assessment
If you receive a status update for your site indicating that it is certified as a Water Managed Site, you can begin operating as a WMS.
Sites which are not certified will be notified and must follow the recommendations given before re-applying for certification.
Once a site is certified, the next step is for your Certified Landscape Irrigation Auditor to conduct and submit a Catch Can Audit or Irrigation System Assessment (ISA) before the end of the irrigation season (Nov. 1).
For sites which are 0.5 hectares or more (Tier 1) a Catch Can Audit will be required. For all other sites (Tier 2) providing an Irrigation System Assessment is sufficient. Contact watermanagedsites@calgary.ca for a Catch Can Audit and Irrigation Site Assessment (ISA) templates.
Catch Can Audit or ISA must be completed and submitted by your Certified Landscape Irrigation Auditor along with your site’s performance report (see Step 5) at the end of the irrigation season for evaluation and re-certification.
Step 5: Site Performance Report
Each year, at the end of the irrigation season (Nov. 1), a Site Performance Report (SPR) must be submitted by your Certified Landscape Irrigation Auditor. The SPR and Audit/ISA results will be reviewed by The City.
If the SPR produces the required water saving performance for the site that year and the audit/ISA meets the required criteria and recommendations for improvement are made, the site can be granted a certified Water Managed Site status for the following year.
Step 6: Certification
When the review of all documentation is complete, The City will notify the applicant of the status of their site. If the site is granted certified status, instructions will be provided related to water use criteria that must continue to be met for Tier 1 or Tier 2 sites under ‘normal conditions’, drought advisory and during outdoor water use restrictions.
WMS certification is granted for one year and is based on annual performance reporting results following each irrigation season.
What are the benefits of a Water Managed Site?
Frequently asked questions (FAQs)
How will my property be identified as a Water Managed Site?
All certified WMS will receive a letter from The City identifying their property as a registered WMS.
Community Standards will be provided with a list of Water Managed Sites for bylaw officers to reference.
Does a Water Managed Site ever have to be re-certified?
All certified Water Managed Sites must have a Certified Landscape Irrigation Auditor submit a performance report on their behalf at the end of the irrigation season. If the site meets the criteria for water savings that year, the site will be re-certified for the following irrigation season.
A 25% reduction in water use is a minimum water savings requirement. If outdoor water use restrictions are enacted during the irrigation season WMS must further reduce their water use by an additional amount during each stage as per Schedule E in the Water Utility Bylaw. At a Stage 4 water restriction WMS must stop operating all irrigation systems.
How can I save water if I don’t have an in-ground irrigation system?
You can still help conserve water and have a beautiful yard by using these outdoor water conservation tips and tools.
