Back in 1986 CULTEC introduced its Contactor and Recharger HDPE septic and stormwater 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 or pipe and stone installations. CULTEC manufactures several different chamber sizes to accommodate almost any site parameter. The products fully open bottom promote maximum infiltration capability and allow for the transfer of high volumes of water at a low velocity. The units may be installed singularly or in series in single- or multi-layer beds. In addition, we have developed our own in-line side portal manifold system which eliminates the need for a conventional pipe header system and water quality unit designed for maintaining our chamber systems. Our CULTEC Separator Row has received third-party environmental technology verification. CULTEC stormwater products are currently modeled in HydroCAD, Bentley Systems, Inc.s PondPack V8i, Autodesks Storm & Sanitary Analysis, and Clear Creek Solutions WWHM-based software.
