I've been hearing a lot about septic tanks and septic systems. What are they and how do they work?

Septic tanks are underground chambers that contain waste from homes and businesses. The waste is treated with bacteria, which break down the organic matter in the waste and convert it into water and carbon dioxide. This process creates a liquid called septic tank effluent, which is then pumped out of the tank through pipes to a nearby treatment facility. There, the waste is further processed before being released back into the environment.
