About this project 

When? 

March-April 

Where? 

Under Rue Bellerive, near the roundabout. 

What? 

Replacing a clapper and a broken valve in the Clément-Jetté bypass chamber.

A valve is an instrument that prevents water from the St. Lawrence River from entering the sanitary sewer system while allowing excess wastewater, in rainy weather, to exit when the capacity of the sewer is reached. Valve: Industrial tap used to interrupt or allow the flow of water in a pipe.

Why? 

Replacing a large valve in the Clément-Jetté diversion chamber that broke during a torrential downpour on July 13, 2023, after 36 years of use.

In addition, the isolation valve, which facilitates inspection and work in the bypass chamber, must be replaced.

In the 1980s and 1990s, the city built several infrastructures, including the Clément-Jetté diversion chamber around 1987, to allow wastewater to be redirected to the Jean-R.-Marcotte wastewater treatment plant and thus avoid discharging water directly into waterways.
