Low Profile Nestable Leaching Chamber Having Increased Water Storage Volume

A plastic chamber for collecting, receiving, detaining, or dispersing water when buried, comprising:

• at least one support pillar, wherein the at least one support pillar includes at least one pillar wall which defines at least one pillar cavity;
• a plurality of chamber ends;
• a plurality of chamber side walls;
• a chamber top, wherein the chamber top includes at least one pillar opening and wherein the chamber top, plurality of chamber ends and plurality of chamber side walls define a chamber internal cavity, and
• wherein the at least one support pillar extends downwardly from the chamber top, and wherein the at least one pillar opening is communicated with the at least one pillar cavity;
• and
• a pillar cover, wherein the pillar cover defines at least one cover opening and is movably associated with the chamber top to be configurable between a first configuration and a second configuration, wherein when in the first configuration the at least one pillar cavity is associated with the at least one cover opening to be uncovered, and wherein when in the second configuration, the at least one pillar opening is covered by the pillar cover.

A method of implementing a leaching chamber having a hollow support pillar and a pillar cover configurable between a first configuration and a second configuration, the method comprising:

• obtaining the leaching chamber having the pillar cover, wherein the pillar cover is configured in the first configuration;
• nesting a like chamber with the leaching chamber such that the pillars of the like chamber are located within the pillar cavities of the leaching chamber;
• transporting and/or storing the leaching chamber and nested like chamber;
• denesting the leaching chamber and the like chamber;
• configuring the pillar cover between the first configuration and the second configuration;
• and
• locating the leaching chamber and/or like chamber within a hole and covering the leaching chamber and/or like chamber with soil.
