Flushing of the Waterworks System

During the next few weeks, Rosemère will be carrying out the progressive flushing of its waterworks system, throughout the entire territory. This will be done weekdays between 7:30 a.m. and 7 p.m.

When you spot crews at work in your neighbourhood, reduce your water consumption and avoid doing laundry during the above-mentioned hours, since water pressure could be low. Furthermore, at the end of the day, check the quality of your water and if it is cloudy, turn on all cold water faucets and let the water run for a few minutes.

Finally, once the work is over, we suggest that you clean your faucets’ filters to facilitate flow and purge your water heater to reduce possible lime deposits.

To know the sectors concerned, consult the Roadwork Information on the website which will be updated regularly according to the progress of work on the territory.


Flushing the waterworks system is necessary to maintain good water quality. We regret any inconvenience arising from this operation and thank you for your collaboration.

For information, contact the Public Works Department at 450 621-3500, ext. 3300.
