* 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.
