Abstract
A molded plastic arch shape cross section stormwater chamber having a corrugated wall comprises separately molded half chambers which are connected by coupling features at a joint region at the top of the chamber, which coupling feature optionally includes at least one locking rod running lengthwise in proximity to the joint region. Preferably, the half chambers are made in the same mold and modified so they are mirror images of each other. The half chambers may be compactly stored and transported in nested condition. Near the point of use, the chambers may be assembled.
