How can I tell the difference between a septic and a sewage system?

A septic tank is a device used to treat wastewater from a building. It works by allowing solids to settle out of the water, then allowing the clean water to pass through a filter before being released into the soil. Sewage systems are designed to transport waste from homes or businesses to treatment plants for processing. These plants use biological processes to break down the waste and produce clean water that can be safely returned to the environment.
