In urban areas, rising land costs are pushing developers to look for innovative stormwater management products that optimize land usage while complying with local environmental regulations.

Our Chambers System functions like conventional stormwater ponds. It works in conjunction with existing storm sewer infrastructure to provide underground retention/ detention and infiltration of rainwater into the ground.

How does it work?

Water is collected in a catch basin or other collective device and is treated by a CULTEC Separator™ Row. The water is then directed into the Contactor® or Recharger® chambers and distributed via the side portal internal manifold and crushed stone embedment. Depending on the system application, the water either infiltrates into the ground, or it is detained and released.

Typical CULTEC stormwater systems are designed by using the largest chamber that meets the site’s depth constraint and system requirements. By choosing the largest available chamber that meets the system's parameters, the number of chambers and the land area required are minimized.


The result: maximized storage volume at the given workable elevations.
