Abstract
Water from a septic tank is aerated, at an above-ground aeration station. The aerated water is infiltrated onto the floor of a trench in the ground through drainage holes in a pipe. The pipe is pressurized with water during dosing. The pipe is arranged to sag down between support posts, whereby water drains completely out of the pipe between dosings, evenly along the length of the pipe.
