Heavy thunderstorms overload Montreal’s sewage system

The large amounts of rain that fell in Montreal in a short period of time overloaded the sewers and forced the authorities to close roads because of the water accumulation.

“We had large accumulations of water, concentrated for very short periods of time, which put us at risk of backflow and flooding,” explains Philippe Sabourin, spokesman for the City of Montreal.

Several Montreal residents said on social media that they suffered a sewage backlog in their home after heavy rains in the early evening, when tornado warnings were issued in the metropolitan area.

“There was an overflow at the Lachine Canal. “This shows us that the sewer lines were at full capacity in some places,” confirms Mr. Sabourin.

There was also water accumulation on several streets that had to be closed to traffic.

At around 5:30 p.m., the following sections were affected:

  • Boulevard Saint-Joseph, between Molson and Fullum
  • Boulevard Langelier between Jarry and Jean-Talon
  • Rue Masson between Iberville and de Lorimier
  • Boulevard Saint-Joseph between Iberville and Fullum
  • Rue Hochelaga between L’assomption and Viau.

“These are places where there is a very steep drop and the water collects in one place and fills up quickly,” says Mr. Sabourin.

In Hochelaga Street, the city recorded “at least three vehicles” that got stuck in the water accumulations.

Mr Sabourin is asking citizens to follow Environment Canada’s guidance as more storms batter Montreal on Thursday evening.

“Everyone is asked to take this very seriously in the coming hours and stay safe at home.”

Highway 15 was also closed between 40 and the Turcot interchange.
