Simplicity & Flexibility | retain-it Stormwater Management System modules are intentionally both simple and flexible. All modules have an 8 x 8 footprint, with interior height options ranging from 1 through 5 feet. Where site conditions permit, modules can be stacked easily to increase vertical interior storage up to 10.67 feet. Modules exceed HS-20 loading requirements and can be installed with minimal cover. Virtually any control or feature imaginable can be designed into the interior of each module – one uniform box with endless design possibilities.
