Can you explain how the septic system works?

The septic tank is a large container that collects and treats waste from your home. It contains layers of soil, bacteria, and water to help break down the waste. This process produces a liquid called effluent, which is then discharged into the drain field. The drain field is a network of underground pipes that carries the effluent away from your house. There are usually two types of drains: gravity-fed systems and pressurized systems. Gravity-fed systems rely on natural forces such as gravity and topography to move the wastewater away from the house. Pressurized systems use pumps to force the wastewater through the drain field. Both systems work by transferring the wastewater to the drain field where it is treated naturally by bacteria and other organisms.
