All homes and businesses connected to Markham's municipal water system have a water meter. Water meters measure how much water you use. You are charged based on the amount of water used.

There are laws around installing, fixing, maintaining, and using water meters. Read Markham's Water Use By-law 2019-53 for more details.

To apply for a water meter, use the online application form:

Installation Details:

Industrial/Commercial/Institutional (ICI) meters (2” and above)

For larger ICI meters, you will need to submit:

  • A copy of the approved site servicing plan
  • An engineer’s letter indicating peak water flow rate and recommended meter size
  • Installer contact and billing information.

Prior to the install date:

We will contact the Applicant/Developer/Builder to confirm dates for water meter delivery, installation and a site survey (2 -3 weeks prior to the install). 

  • Site survey includes taking measurements, confirm material requirements, plan equipment, and arrange any equipment necessary with the builder for handling the meter (if required).

On the install date:

  • The City contractor will be on site and proceed with installation.
  • The water meter will be delivered to the site prior to or on this date along with parts.
  • The builder will need to provide equipment to unload meter and move into place, which may involve removing chamber lid depending on size of opening.
