1. A module for receiving stormwater when buried in permeable media, comprising:
a base having a substantially horizontal upper surface and a multiplicity of fittings arranged on the upper surface in a first pattern;
a plurality of columns extending vertically from the base, each column having a lengthwise axis, an upper end, and a lower end, each lower end being mated with one of said fittings;
a first plate, situated at a first elevation from the upper surface, the first plate having a plurality of holes arranged according to said first pattern, wherein each column extends slidably lengthwise through one of said holes;
a plurality of self-acting engaging means comprising a latch and a receiver, configured to secure the first plate to each column at the first elevation and to prevent downward motion of the first plate; and,
a second plate, situated at a second elevation from the upper surface, the second elevation being higher than the first elevation, the second plate having a plurality of holes arranged according to said first pattern, wherein each column extends slidably lengthwise through one of said holes; and,
a plurality of self-acting engaging means comprising a latch and a receiver, configured to secure the second plate to each column at the second elevation and to prevent downward motion of the second plate;
wherein, with respect to angular orientation about the lengthwise axis of each column of a multiplicity of said plurality of columns, the angular orientation of the receiver of the plurality of self-acting engaging means of the first plate is different from the angular orientation of the receiver of the plurality of self-acting engaging means of the second plate.
