What is a septic system, and how does it work?
assistant
A septic tank is a large underground holding tank that collects waste from the home. The septic tank has a series of pipes that lead to an absorption field or drain field. The drain field is typically made up of gravel or stone and is located in the ground outside the house. The pipes from the tank are buried in the drain field, which allows the water to filter through the soil and into the groundwater below. This process helps to purify the water before it enters the aquifer.
