Unidirectional flushing to be carried out in the Dorion sector

The City of Vaudreuil-Dorion wishes to inform its citizens that it will be proceeding with the unidirectional flushing of the Dorion water system along with the  inspection of fire hydrants beginning on October 20th between 7:30 a.m. and 4:30 p.m. for a period of approximately one month.

This work is usually done in the spring, but the situation caused by the pandemic had forced the municipal administration to postpone it until 2021. However, recent problems with discoloured water in the Dorion sector led the City to reconsider its strategy and proceed with the work immediately.

Flushing involves increasing the speed of water flow through the system to remove particles and debris that may form on the conduit walls. The operations are carried out using pre-determined flushing routes that promote better cleaning.

This large-scale operation may cause a slight drop in water pressure with or without a reddish discoloration. This may give rise to certain problems such as stained clothing. The City recommends waiting until after 4:30 p.m. on weekdays to do the laundry, or until the weekend, throughout the period required to complete the work. Should the water become rust coloured, citizens are advised to turn on the bath's cold water tap and let the water run until it becomes clear.

To find out which water system your property is connected to, citizens are urged to use the search by address option on the City's website which can be found on the home page. If you have any questions, please contact the Public Works Department at 450-455-3371, option 3.
