Abstract:
1. A system for constructing an underground fluid distribution assembly which is constructed for receiving effluent liquid from a septic tank or sewage system and absorbing and distributing the liquid to soil, surrounding the system, said system comprising: A. a first, elongated, continuous, substantially flat, pre-folded, multi-panel forming sheet of material comprising B. a second, elongated, continuous, substantially flat, pre-folded, multi-panel forming sheet of material comprising C. said first elongated, continuous, substantially flat, pre-folded, multi-panel forming sheet of material being mounted in position longitudinally extending in juxtaposed, spaced relationship with the second, elongated, continuous, substantially flat, pre-folded, multi-panel forming sheet of material forming therebetween an elongated, substantially continuous, corridor or passageway; D. said second channel of said first elongated, substantially continuous, substantially flat, pre-folded, multi-panel forming sheet of material being aligned with said second channel of said second elongated, substantially continuous, substantially flat, pre-folded, multi-panel forming sheet of material, with both of said second channels being open to and communicating with the elongated, substantially continuous, corridor or passageway; E. said fourth channel of said first elongated, substantially continuous, substantially flat, pre-folded, multi-panel forming a sheet of material being aligned with said fourth channel of said second elongated, substantially continuous, substantially flat, pre-folded, multi-panel forming sheet of material, with both of said fourth channels being open to and communicating with the elongated, substantially continuous, corridor or passageway; F. granular fill material positioned in and substantially filling said elongated corridor/passageway, both of said second channels and both of said fourth channels for providing a filtration system therein; and G. sand fill material positioned in and substantially filling of the first channel and the third channel of said first elongated, substantially continuous, substantially flat, pre-folded, multi-panel forming sheet of material and said first channel and said third channel of said elongated, substantially continuous, substantially flat, pre-folded, multi-panel forming sheet of material, providing filtration means for receiving and absorbing liquid passing through said wall members from said granular material to said sand material.
