Back in 1986, CULTEC introduced its Contactor and Recharger storm water chambers to the industry and helped to begin a revolution towards the usage of plastic construction products. Since then, several product developments and strategic alliances have made CULTEC a cutting edge R&D-based manufacturer. CULTEC chambers may be used as subsurface retention or detention systems; as replacements for ponds, concrete structures, crate, or pipe; and stone installations. CULTEC manufactures several different chamber sizes (8.5 in. to 48 in. high) able to accommodate almost any site parameter. The product’s perforated sidewalls and fully open bottom promote maximum infiltration capability and allow for the transfer of high volumes of water at a low velocity. In addition, we have developed our own side portal internal manifold system, which eliminates the need for a conventional pipe header system, and we manufacture a water quality unit designed for maintaining our chamber systems. To assist in the design phase, CULTEC offers these free design tools and assistance: CULTEC Stormwater Design Calculator; CULTEC StormGenie Automated Drawing Program—an AutoCAD plugin used for drawing CULTEC storm water systems; preliminary calculations and job specific CAD details; and 5-node HydroCAD CULTEC custom edition.
