Work is under way to install a new force-main sanitary sewer on Ashwell Drive, which will eventually hook up to the new waste water treatment plant being built for the Molson- Coors brewery.

Construction on the new sewer and sanitary pump station was contracted to Jakes Construction.

The force main is being built using a device to ‘burst’ an old 350-mm sewer pipe which is no longer being used. A special machine will pull a new 300-mm pipe through the new space inside the old pipe. This method means they don’t have to dig a trench all the way along Ashwell, which will help to keep traffic congestion to a minimum during construction, said staff.

This burst technique was used from Parr Road up to McCutcheon, over to Deans and will run up Ashwell and then down Wolfe towards the Wastewater treatment plant. For the remaining sections of pipe, which includes a section on Wolfe Road, and from Parr Road to the new brewery pump station, the pipe will be installed using the traditional trenching method.

Staff anticipate the installation will be completed by mid-August, at which point the work will be concentrated on the Molson site to construct the sanitary pump station for the brewery. All the work should be completed by the end of October.
