Abstract
A rectanguloid shape six-walled thermoplastic box for receiving and dispersing stormwater, when part of an array of like boxes that is buried in media, has interior bracing in the form of an irregular polyhedron structure comprised of up to six hollow pyramids. The truncated apexes of the pyramids meet near the center of the box. The base of each hollow pyramid is contact with, attached to, or integral with a wall at the location of an opening within which is a grate. A box may be injection molded as a single piece molding with living hinges. Alternatively, the pyramidal polyhedron structure may be formed as a separate element and placed within the walls of a box.
