  • 1.  Major melting in Montreal causes sewer overload

    Posted 01-24-2019 10:09 PM
    Hello,

    I wanted to share some pictures from my walk around downtown Montreal today. Very interesting from an engineers perspective doing her masters in stormwater management. I am wondering how this situation could have been delt with differently. Lots of snow still present on the streets blocking the manholes and preventing the water from draining. Also a matter of the system's capacity being breached since such a large amount of snow had fallen a few days prior. Just wondering if they need to make sure those clearing the snow make a point to unblock the manholes... other ideas?

    Comments appreciated :)

    Thanks for sharing, Julia! That looks like quite the ordeal to drive or walk through. And I thought our lingering slush in Minneapolis was bad. I'm not sure if there's a formal solution to this issue, but one idea I saw while in Sapporo, Japan was to install snow melting pits (picture below). To avoid damming up the creek, these off-line pits have hinged grates that can be opened so that snow can be shoveled in and allowed to melt slowly. I wasn't around in the winter to see how well they work, though.

    These things should have been considered during construction.
