The main difference between a septic tank and a sewage system is that a septic tank is designed to treat wastewater from a home or building, while a sewage system is designed to handle wastewater from multiple buildings. Septic tanks are usually made of concrete, fiberglass, or plastic, and they contain a series of compartments where solids settle out and bacteria break down the organic material in the wastewater. This process produces methane gas which is then released into the atmosphere through a vent pipe. A sewage system typically consists of a network of pipes that carry wastewater away from homes and businesses to treatment plants. These systems use chemicals and processes to remove pollutants before the water is discharged back into the environment.
