Septic systems are widely used for waste treatment in homes. They consist of a septic tank that captures solids and liquids, preventing solids from entering the disposal field. Gases from anaerobic digestion are vented out. Treated wastewater flows to a distribution box and into trenches, where it interacts with soil, forming a biomat. Regular maintenance, including pumping every three years, is crucial for system longevity and environmental protection.
