We offer a variety of solutions for rainwater detention and filtration systems for export, including HDPE stormwater infiltration chambers and AASHTO M-294, ASTM F2306 HDPE storm drain pipe and fittings, and treatment and filtration systems for challenging installations featuring high groundwater, soils with low permeability, bedrock, or other limiting factors.



Cultec Recharger and Contactor chambers, which replace conventional stormwater management systems. The chambers may be used for drywells. They may be installed in trench or bed configurations according to site restrictions or client preference. These chambers are typically installed subsurface beneath parking areas to capitalize on use of space, but they may be placed in grassy areas as well.
