<p>The sewage treatment system (1) includes a sewage holding tank (2) for reception of raw sewage from a domestic dwelling. A diffuser assembly (7) at the bottom of the tank (2) is operated for a preset period to aerate sewage liquid in the tank (2). After aeration and a subsequent settling period, a discharge pump (6) is operable to discharge a preset amount of treated liquor from the tank (2) for dispersal through an irrigation system buried in the ground remote from the tank (2). <Figure 1></p> |
