Abstract (en)
[origin: WO2017210054A1] The application concerns a modular storm water retention system and a method of constructing the retention system whereby the system includes a plurality of modular retaining units (1040) which are selectively connected together to form an interior chamber volume (1106) for collecting storm water run-off directed into the chamber volume. A plurality of modular trays (1180) are engaged with the top portions of the respective retention units to prevent relative movement of the retention units and eliminate, or substantially reduce, the need for porous material to be installed in and around the retention units greatly increasing the excavation void space usable for water collection and retention. The trays further support the backfill material and prevent passage of the backfill material into the void space below the trays.
