A system and method is disclosed for distributing greywater to a soil bed without significant erosion of the soil bed. An interior tube defining at least one aperture is disposed within an exterior tube. The interior tube and the exterior tube are immersed in a soil bed for aerobic decomposition of greywater discharged from the greywater distribution apparatus into the soil bed. The apertures of the interior tube are sealed from the soil bed when greywater is not being discharged into the soil bed. Directing greywater into the interior tube at a sufficient pressure causes greywater within the interior tube to be directed through the apertures. The exterior tube baffles the flow of greywater through the apertures, thereby diminishing the velocity of the greywater. The greywater then passes between the interior tube and the exterior tube and is discharged from the exterior tube through a slot which extends along a substantial portion of the exterior tube. The greywater is thereby discharged from the greywater distribution apparatus at a velocity and a flow rate which is sufficiently slow to prevent significant erosion of the soil bed. |
