ABSTRACT:
The performance of a leach field of a septic tank type wastewater treatment system and other analogous devices is enhanced, maintained or rejuvenated by flowing air or other active gas through conduits of the system. Air is flowed serially through leaching chambers, perforated pipes in stone filled trenches, pits and the like, and the adjacent soil where wastewater treatment takes place. In alternate embodiments, conduits are pressurized or evacuated; and, auxiliary pipes are buried in vicinity of the conduits. An air mover creates a differential pressure sufficient to effect a desired physical or biochemical change in the soil adjacent the conduits, variously to to an extent sufficient to push water from saturated soil and to change the gas composition in the soil. Different valve devices and piping configurations are used to manage the desired flow of air and wastewater.
