*The wastewater usage is your water usage multiplied by 90% to reflect that not all of the water delivered to your home over 12 months is sent to the wastewater system . This percentage 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 Water Rates

A residential flat rate customer is a dwelling that does not have a water meter installed to measure the amount of water used. Learn more about water meters and how you can get one installed.

Water Utility rates for those 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

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).

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.

Residential customers that do a large amount of outdoor watering might consider having an irrigation meter installed in combination with their residential water meter. However, 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.

What do my rates and charges pay for?

Delivering safe and reliable drinking water, treating wastewater, providing flood protection and maintaining a system of pipes, plants and pumps for a city of 1.3 million is complex.

Your utility rates are set at the lowest amount possible to deliver current services, and provide enough funding to expand, upgrade, maintain and repair our water, wastewater and stormwater infrastructure.

Utility rates and service charges are set to recover the actual cost of providing water, wastewater treatment and managing stormwater. The water utility does not profit from rate and service charge adjustments.

These services are entirely funded by rates paid by customers. The water utility does not receive any funding from property taxes.

How to read your utility bill

Water charges are calculated by the number of days on your ENMAX bill. The number of days billed can vary, however it is typically 28-30 days.

Average water use in Calgary - A single person in a home uses seven cubic metres (m3) of water or 7,000 litres every month.
