Soil Absorption

Soil absorption is the ability of soil to combine with, and hold water and other liquids. It is the process of soil absorption that allows a septic system drain field to process effluent from the septic tank. When soil absortion stops it causes flooding of the field resulting in effluent rising to the surface of the soil. Flooding also deprives the soil of oxygen, which in turn kills off beneficial bacteria needing oxygen to survive.
