Do you own a building that is partly or wholly used for non-residential purposes? Your building must have a water meter installed. Here’s how to do it.
Plan the preparatory work
Before installing a water meter, you must ensure that all necessary work to bring your plumbing up to code has been completed. This includes, but is not limited to, the addition of faucets and the installation of a bracket to solidify the plumbing, a grounding system to prevent electrocution, a meter connection, a bypass and a backflow prevention device (in French, a “dispositif antirefoulement” or DAr).
Making sure your plumbing meets the standards
When adding a water meter, you must install backflow prevention devices (DAr) to protect the building’s drinking water system, as required by the Régie du bâtiment du Québec. The DAr is usually installed on the same pipe segment as the meter.
Starting the installation process
You must first complete the general information sheet and an inventory of your water-consuming fixtures. Then send us your documents by e-mail.
Please allow approximately two weeks for your file to be opened. A municipal employee will contact you to guide you through the preparatory work to be done.
Coordinating the work to be done
The water meters and their ancillary equipment will be supplied and installed by a municipal employee. Homeowners can ask to install their own meter themselves.
During the installation of the meter, there may be a temporary interruption of the potable water supply to your building or a slight decrease in water pressure. It is your responsibility to put measures in place to prevent damage to your property.
