How to install a water meter in a new non-residential building

Last updated May 20, 2022

Are you planning to construct a building that will be used in whole or in part for non-residential purposes? It must be equipped with a water meter. Find out how to install it.

Before starting construction

To get your building permit, you must have already started the process of installing a water meter. In order to avoid delays in your project, you must submit your meter installation request at least 60 days before the start of your work.

Starting the installation process

You must first complete the general information sheet and the inventory of water-consuming fixtures in the building or have your engineer’s hydraulic calculations available. Then contact us by phone to open a file and send us your documents by email.

Please allow two weeks from the date you submit your documents for a municipal employee to review your file and provide you with the necessary documentation for the installation.

Installing the meter

The water meter and its ancillary equipment are provided by the city, but it is your responsibility to install them. You will have 90 days to install them after receiving the documentation.

Required documents

  • General information sheet
  • Inventory of water-consuming fixtures
