CULTEC, Inc. is the manufacturer of the Contactor® and Recharger® plastic septic and stormwater chambers. The chambers may be used as subsurface retention or detention systems, as replacements for ponds, concrete structures or pipe and stone installations, or as replacements for conventional septic leach field lines. Perforated sidewalls and a full open bottom promote maximum infiltration and allow for the transfer of high volumes at low velocity. CULTEC has been manufacturing chambers since 1986 and has the largest variety of sizes to fit almost any installation requirement. CULTEC can assist in stormwater design by performing preliminary calculations and supplying AutoCAD® layouts free of charge.
