On Wednesday, November 4, scheduled work by Ville de Montréal on its main water network caused a higher-than-expected increase in pressure. This surge led to several water main breaks, leaks and flooding in Westmount and in the borough of Ville-Marie.
Several areas of Westmount experienced drops in water pressure and water service interruptions, as well as power outages required to carry out the repair work.
City of Westmount crews worked throughout the evening and overnight, in constant contact with Ville de Montréal, to limit damage and restore service.
Ville de Montréal crews intervened to stabilize the pressure, which has returned to normal in most areas. Water quality was not compromised at any time, as confirmed by Ville de Montréal.

Motorists and pedestrians are asked to use caution near work zones and follow posted signage.
