How does a septic system work?
assistant
A septic system is an underground wastewater treatment system. It consists of a septic tank, which receives the wastewater from the home and treats it with bacteria, and a drain field, which is usually made up of gravel or stone that allows the treated water to flow away from the home. The drain field is designed to filter out solids and other pollutants before they can enter the groundwater. This type of system is called a subsurface wastewater disposal system because the wastewater travels through soil before entering the ground water.
