The Context

Design of 4 HydroStor retention systems

As part of the construction of Solar Uniquartier, the first advanced district in Quebec, the contractor Allia Infrastructure had to build a large retention system with groundwater replenishment under the future park located in the heart of the district. Backed by Soleno’s expertise, GBi Consulting’s design team chose to rely on polymer products as HydroStor retention solutions offered many advantages.

The Solution

GBi’s design team chose to build four retention systems made of HydroStor underground chambers. For the first system of 15 rows, 1078 HydroStor HS180 chambers were installed under the future large park of 12,000 m2, occupying an area of 5290 m2. This large system will store 5600 m3 (197,762 ft3) of water for heavy rain events. In addition, to treat the water before it is retained, a pretreatment unit has been incorporated into the retention system.
