Abstract
A leaching tube includes a tube base for burial in the earth to disperse or gather liquids, the tube base having a semi-rigid spiral, or helical, form with spiral, or helical, ribs, and spiral, or helical, openings along the length of the tube, a water permeable covering wrapped around the tube base, and a vertical frame inside the tube. The frame is a pipe frame that supports the spiral tube base and also provides an air conduit for air injection inside the tube. The frame is fixed to the spiral ribs on the top and bottom of the frame. End plates can be fixed to the frame by bridge pieces and pins. Sections of tubes can be connected end to end by bridge pieces and pins. The pins can be pipe pieces that can also provide air connections between the tube sections. One of the end plates can provide an inlet opening for an effluent inlet pipe.
