What is the difference between a septic tank and a sewage system?
assistant
A septic tank is a small, underground wastewater treatment system that treats domestic wastewater from a building. It consists of a tank or container in which solids settle to the bottom and water passes through a filter bed before being discharged into a drain field or leaching system. A sewage system on the other hand is an infrastructure network of pipes, pumps, and treatment facilities that collects and transports human waste away from buildings for treatment at a wastewater treatment plant or other treatment facility.
