What is the difference between a septic system and a sewage system?
assistant
A septic tank is a small, underground chamber that collects waste from a home's plumbing system. The septic tank then filters out solid waste and sends it to a drain field where bacteria break down the waste into water and solids. This process is called anaerobic digestion. Sewage systems collect wastewater from homes and businesses and transport it away from residential areas through pipes. These pipes are typically connected to a central treatment plant or sewer line.
