The contractor Les Entreprises Claude Chagnon, under the supervision of Mr. Philippe Déry Rouleau, Project Officer, proceeded to the installation of four underground retention systems; three with HydroStor chambers and one with StormChamber chambers. Installed on a stabilization geogrid, the 65 HydroStor HS180 chambers and the 31 StormChamber chambers, all surrounded by clean stone, will allow the storage of 478.7 m3 (16 880.4 ft3) of water for heavy rain events. A non-woven TX-90 separation geotextile was installed on all excavated areas and also used to cover the clean stone.
