Flushing the water supply system

Starting May 5 and during the next 7 weeks, Rosemère will be carrying out the progressive flushing of its waterworks system, throughout the entire territory. This will be done on weekdays between 7:30 a.m. and 7 p.m.


During the entire operation, water pressure could be low. If the water becomes cloudy, turn on all cold water faucets and let the water run for a few minutes.


To follow the progress of the work by sector and to find out more about the flushing operations, visit our Web page.

If you have any questions, please contact the Public Works Department at 450-621-3500, ext. 3300.
