The StormTech SC-740™ Chamber optimizes storage volumes in relatively small footprints. By providing 2.2 ft³/ft² (minimum) of storage, the SC-740™ chambers can prevent excessive excavation, backfill and associated costs.

StormTech chambers have been subjected to advanced in-ground testing protocols and high-level industry expert review. They have been evaluated to support HS-20 live loads following current AASHTO procedures for loads, structural capacity and factor of safety when installed per StormTech's Chamber Installation Instructions. StormTech chambers are molded from Polypropylene resin, which is inherently resistant to environmental stress cracking and chemicals typically found in stormwater runoff.
