Protect the landscape and prevent flooding even in limited footprints with the NDS StormChamber® system. The modular storm chambers can be configured in unique layouts to fit the requirements of the job site, and can also be stacked in layers. This advanced storage and sediment removal system is more cost-effective and requires less maintenance than other underground stormwater systems. The 34 in. high drainage chamber offers a minimum installed storage of 107 cubic feet and internal chamber volume of 69 cubic feet. Place the middle unit (or multiple middle units) between the start unit and end unit to form a row. To increase storage, additional rows can be interconnected with pipe from side portals. StormChamber units are made of thermoformed high-density weight polyethylene, engineered to withstand extreme environments, exceeds the AASHTO H-20 design load, and allow for deeper cover than other systems. Use included SedimenTrap™ devices to capture sediments and help extend the lifespan of the system.
