What is a septic system, and how does it work?
assistant
A septic tank is an underground sewage treatment system that uses bacteria to break down waste in the tank. The liquid waste from the tank then flows into a drain field, which consists of porous material such as gravel or sand that allows the water to filter through it. This process helps remove harmful pollutants before they reach the groundwater. The filtered wastewater then drains into the surrounding soil where natural processes help purify the water further.
