For a brief period on Thursday, all water services in the West Island were to be shut down because of a faulty automatic shutoff valve.
Montreal has issued a boil-water advisory for a large portion of the West Island, affecting mainly municipalities in the North Shore.
The city lifted the advisory at 8:20 p.m. tonight.
According to the city’s drinking water service:
About an hour and a half ago, we received a notification from the Sûreté du Québec that a critical valve in the water main at 668d St-Jean Blvd. turned on and was not turned off. Because of this pressure, we lost the connection between the water main and the main hydrant … that we’ve worked for more than a year on getting to, but also because of the third piece of equipment that we have that we normally use.
The pumps will be operating starting this morning.
The following municipalities have been affected:
Baie d’Urfé, Cavendish, Granby, Lakeshore, Midview, Normandy, Pierrefonds-Roxboro, Ste-Anne-de-Bellevue, St-Lazare, Ste-Anne-de-Bellevue, St-Lazare, St-Lazare/Dorval
Water depots were closed and the depots of southern Ste-Anne-de-Bellevue were briefly evacuated. They are due to reopen at 10 a.m. today.
During the advisory, an estimate on when services would return to normal was not made.
As of 1 p.m., an Sûreté du Québec check indicated water pressure was restored in all of the affected municipalities.
