Water rates and service charges

Your rates and service charges are changing for 2021

Each year we review and adjust rates and service charges to ensure we can continue to deliver the City utility services you value.

In 2021, residential metered customers will see their bill decrease.

  • The typical monthly water bill will decrease from $115.43 to $112.84 in 2021, a 2.2 per cent decrease.

Delivering services you value

Rates and service charges are set at the lowest level possible to:

  • cover the cost of providing water, wastewater, and stormwater services
  • perform required maintenance and upgrades to the system

Utility customers ensure we are able to deliver safe, reliable drinking water, treat wastewater safely and protect the river now and for years to come.


Residential rates

Residential Metered (based on a household using 19m3 per month)

Residential metered customers include residences containing one or more dwelling units that are individually metered by The City, and those with less than five dwelling units (regardless of how each is metered).

* Not all of the water delivered to your home over 12 months is returned to the wastewater system. The wastewater usage is your water usage multiplied by 0.90 to reflect that over the course of the year you return around 90% of the water used to the wastewater system. This percentage is used year round and recognizes seasonal fluctuations where you send more water to the wastewater treatment system in the winter months and less during the summer months because of outdoor activities like watering.

Residential Flat Rate

Residential customers that do not have a water meter to measure the amount of water being used are billed on a flat rate.

Visit the water meter installation page to arrange to have a meter installed.

Water Utility rates for residences on a flat rate are calculated according to the square feet of actual lot area and gross building area based on the original development permit submitted to The City of Calgary Planning department. For detailed information on your flat rate calculation, please call 311.

The following 2019-2022 Water Utility rates are based on 30 days of service, which means the amount on your bill may vary depending on the number of days you have been billed.

Residential Irrigation Meter Rates

Irrigation meter water rates are higher than residential meter water rates because this type of use contributes significantly to our peak demand, our highest water use period. Our water system needs to be sized to accommodate this peak demand so a higher proportion of cost is associated with this type of use.

Customers that are installing or considering installing an irrigation system are required to have the all of the irrigation components installed at their own expense and separated from the residential plumbing system. The City of Calgary will install an irrigation meter at no charge. Customers are responsible for basic service charges year-round but are only charged for water service and consumption charges (no wastewater or drainage charges).

Customers should consider the plumbing costs associated with the installation of an irrigation system, the size of space they will be irrigating, how much water they are planning to use and the service charge of the additional irrigation meter prior to deciding to install an irrigation meter to ensure this service will provide savings.
