Abstract:
1. A method of fabricating a septic tank, said method comprising pouring hardenable fluid material around a plug and within a mold, where said plug is at an elevated position with respect to a lower surface of said mold, such that said septic tank may be fabricated in a single pour so as to have a vertical cross-section that forms a self-bounded loop, where a brace member positioned vertically above said plug both maintains said elevated position and holds said plug in a submerged position, while said plug is immersed in said hardenable fluid material, where said brace member may be separated from said plug after said hardenable fluid material has hardened, and where at least one retaining member adjacent a surface of said plug causes said fluid material to form an opening into said septic tank, where said plug is assembled from a plurality of panels, and said method further comprising the step of disassembling said plug after said fluid material has hardened and removing said panels from the interior of said septic tank through said opening
