Water Saving Tips, FAQs, more information

Are you a multi-family customer?

Multi-family customers include:

  • Apartment buildings (a single building comprised of five or more dwelling units with shared entrance facilities)
  • Multi-family residences with more than five attached units NOT individually metered by The City.

For these residences, there may be one common City water meter that services all of the units in the building or complex, under the responsibility of a condo or property management company.

If you are unclear about which services are your responsibility:

Please review your ENMAX bill or check with ENMAX Customer Care.

You can also check with your condo or management company to see if water utility charges are included in your monthly fees.

* Not all of the water delivered to your home over 12 months is returned to the wastewater system. In 2024 the wastewater usage is your water usage multiplied by 0.95 to reflect that over the course of the year you return around 95% 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.

Your rates and charges pay for three important services
