*The amount you pay for wastewater is calculated based on the fact that the wastewater produced is estimated to be 90 per cent of water usage over a year. This reflects that some water (e.g. outdoor watering) is not returned to the treatment plants. For example, for a household using 19m3 of water per month, the wastewater calculation is: 19m3 x $1.465/m3 = $27.835 ($1.465 is 90% of the $1.6278 wastewater rate).

For questions about your wastewater calculation call ENMAX at 310-2010.

Water Residential Flat

Edit accordion

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.

Water Residential Irrigation

Edit accordion

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.
