Press Release

Rivière des Mille Îles


Québec City, October 22, 2010. – The ministère du Développement durable, de l'Environnement et des Parcs releases a new plan in regard to work in the rivière des Mille Îles. The changes will enable the project to remain on budget and ensure that the anticipated delays stemming from technical problems encountered during recent months on the work site are kept to a minimum. The work itself will be completed by the end of 2010.

This scenario has been made possible thanks to new knowledge obtained by the Ministère during the summer of 2010, particularly regarding the performance of area municipal water treatment plants during low water season. Under the new plan, excavation will be concentrated on the north shore of the river but will cover a larger area within the existing cofferdam.

Minimum water flow once work is complete could reach between 25 and 30 cubic metres per second, which will guarantee a safe, permanent supply of drinking water to more than 400,000 residents of Montréal’s northern tier.

The Ministère will ensure that the balance between public security and environmental protection is maintained in spite of the changes to the work plan. Moreover, the impact of the work on the natural environment should be less than initially forecast, since the total excavation zone will be smaller than originally planned.

Work had advanced at a slower pace than anticipated, notably due to problems related to dewatering the site, a self-propelled crane overturning, the complexity of the work involved in consolidating the CN pillars and a significant rise in the water level at the beginning of October.

Citizens are invited to visit the Web site for all additional information concerning the work in progress, telephone toll free 1 800 561-1616.
