GRO Tank Stormwater Detention Modules

2″ MODULE

GRO 2” Stormwater Detention Modules are a lightweight, effective stormwater storage solution to maximize retention and /or detention. Each detention module is 2” thick, can be stacked up to 10’ high, and easily configured for efficient use of space. Designed as an open shell, these modules encourage infiltration with 90% internal and surface void area available for high capacity stormwater capture.

Depth: 2″ to 10′ | Stormwater Retention: .48 to 28.8 cf
