The main difference between a septic tank and a sewage treatment system is that a septic tank is designed to treat wastewater from a building's plumbing fixtures, while a sewage treatment system is designed to treat wastewater from a whole house or multiple houses. A septic tank is usually made of concrete and has an outlet pipe that connects it to a drain field, which consists of a network of underground pipes that carry the wastewater away from the home. A sewage treatment system generally includes a pumping station, where the wastewater is pumped into a large container called a septic tank, then treated with chemicals before being released into a nearby body of water such as a river or lake.
