How do septic systems work?
A septic tank system uses natural processes to treat and dispose of the waste water generated in your home or business. It typically consists of a septic tank and a drainfield, or soil absorption field. The septic tank provides the first step in treatment. As wastewater flows into the tank, the heavier solids settle to the bottom to form a sludge layer, and the lighter solids, greases, and oils float to the top to form a scum layer. The liquid wastewater from the tank flows into gravel-filled trenches in a typical drainfield where it is distributed via perforated pipes and then treated by the natural soil system. The diagram below shows the components of a typical system.
