发明名称 Apparatus for rejuvenating a drainfield or drywell
摘要 An apparatus is provided for cleaning and rejuvenating septic tank sewage systems. Where the septic tank has a drainfield associated therewith, the method comprises penetrating the ground near a drainfield lateral, and agitating the area near the drainfield lateral while simultaneously applying suction to the drainfield lateral. Accumulated scum and waste is thereby removed from the drainfield lateral. Where the septic tank system has a dry well associated therewith, the method comprises penetrating the bottom of the dry well and agitating the area underneath the dry well to form accumulated scum and waste into a froth or malt at the bottom of the dry well, and removing the froth or malt by suction. The apparatus of the present invention comprises a penetrating nozzle attached to an articulated boom assembly for penetrating the ground near a drainfield lateral or underneath a dry well to apply forced air or fluid or suction to agitate the area near the drainfield lateral or underneath the dry well.
