A first blue-green alley in Pointe-Saint-Charles

2017-04-16

The artery along Building 7 in Pointe-Saint-Charles will be transformed within three years into a blue-green alley, a first in Montreal. This is an innovative system that consists of diverting stormwater from the sewers in order to reduce the discharge of wastewater into the St. Lawrence River.

The main idea of ​​the Blue-Green Lanes pilot project is to disconnect the roof drains in order to direct rainwater to a drainage system installed in Le Ber lane. Concretely, this method would make it possible to divert from the municipal sewers an amount of water equivalent to 2.5 Olympic swimming pools per year, which would then be used for more ecological purposes.

“Everything remains to be designed with the citizens, but we plan to filter the water or use it to water the plants or to clean, for example. In short, everything that we already do with drinking water, but that we shouldn’t do,” underlines Pascale Rouillée, development director at Vinci Consultants, the Pointe-Saint-Charles company carrying the project.

The Collectif 7 à nous, the People’s Housing Society of East Montreal (SHAPEM) and the Montreal Urban Ecology Center (CEUM) are also overseeing the project. Together they form the Blue-Green Alleys Alliance.
