StormChambers Solve Montreal School Board’s Combined System Problems


A site at 1350 Boulevard Cremazie East was selected by the Montreal School Board for the parking lot expansion. The storm water system was designed to capture runoff from the parking lot and roof. Although the City of Montreal and the Montreal School Board preferred low impact development construction solutions, the options for the new storm water system were limited because the soils were not well suited for an infiltration-type system.


The School Board had considered the use of plastic storm water chambers as a cost savings measure, but then began looking for more expensive traditional types of storm water management systems. Their options became more constrained because the City of Montreal was served with a combined sanitary/storm water system in that area. Therefore a non-infiltrating type of storm water system was required. Any back flow from the combined system had to be prevented from leaching into the ground.

Their problem was solved after consultation with Soleno in Saint-Jean-sur-Richelieu, just outside Montreal. Soleno is Canada’s largest manufacturer of HDPE pipe and Eastern Canada’s exclusive distributor of HydroLogic Solutions’ StormChamber and SedimenTrap. Soleno was able to make the School Board aware that plastic storm water chambers are not restricted to use for infiltration purposes. Soleno designed a StormChamber system lined with an impermeable geomembrane that would prevent back flows from leaching into the ground. The StormChamber system solved the School Board’s problem and still made it possible for them to achieve the cost savings of a plastic storm water system.


  • “Because we have installed several StormChamber systems, a lot of engineers have asked for advice on competing plastic chambers. We have always recommended the StormChambers. They far exceed the competition on cost and ease and speed of installation.”

    Dean Clark General Manager, SECO, LLC, Chelton, WA
  • “Much less expensive and much quicker and easier to install than the 64″ pipe originally speced for the project.”

    Joe Szabo Owner, J&R underground contractors, Milan, MI
  • “Significantly faster and easier to install than pipe. Significantly less staging room needed and a lot fewer trucks to receive and unload.” (The equivalent of 213 LF of pipe nest on one pallet, 1,913 LF on one truck.)

    Bob Dawson Owner, Dawson Company, Woodbridge, VA
  • “We have installed several StormChamber systems because we find them to be a lot less expensive and quicker to install than the competing systems and we can install them in two layers on very confined sites.”

  • “We were surprised by the ease of use of the system and greatly appreciated support provided. We are already looking forward to building our next StormChamber project!”

    “I also like that it can be cleaned by air vacuuming via inspection /cleanout ports instead of using water. Anytime you have to clean something with water, then you have to have a truck that collects the water and the sediments in it. Depending on where you can dump that, it can get much more costly as opposed to going out with a vacuum truck.”

    Steve Pandish Director of Water Resources for the engineering firm of William H. Gordon Associates in Chantilly, Virginia

    “The choice of StormChambers met the design requirements for strength in such a way that the chambers could be stacked three deep with 30 feet of cover, if needed. Strong enough to sustain the impact of 18-wheelers loaded with steel. They also were 30 percent more cost-effective than other options.”

    “It was easy. There were no difficulties once the owner decided on the StormChamber system. The project is holding up to heavy traffic, pump tracks, and cranes.”

    "We were amazed by the simplicity of this system and have appreciated the support from the Soleno team during the entire project. We are already looking forward to designing another project using the StormChamber!"
