Can you explain how the septic system works?

The septic system is a wastewater treatment system that uses bacteria to break down organic matter in wastewater. It consists of three main parts: the septic tank, the distribution box and the soil absorption field. In the septic tank, the solid waste is broken down by anaerobic bacteria which produce methane gas as a byproduct. This methane gas then passes through the distribution box, where it is mixed with air before entering the soil absorption field. Here, the methane gas is consumed by aerobic bacteria which convert it into carbon dioxide and water. These bacteria are also responsible for breaking down the remaining organic matter in the wastewater and producing harmless end products such as carbon dioxide and water.
