Abstract
The functioning of the leach field (40) of a septic tank (20) type sewage system is maintained or rejuvenated by flowing air or other active gas into the system's conduits (34, 56), for instance, leaching chambers or perforated pipes in stone filled trenches. Differential pressure created by an air mover (71) forces air or other active gas to flow through the soil (38) adjacent the conduits (34), to an extent sufficient to push water from any saturated soil and engender desirable aerobic biochemical conditions in the soil. In alternate embodiments, conduits may be pressurized or evacuated. Valves (70) and other plumbing (68) are provided to control air flow and enable continued function of the sewage system during air flow treatment. Auxiliary piping is buried adjacent the trenches of the leach field and pressurized or evacuated to cause air flow through the soil and or the conduits of the leach field.
