<human>: I have a septic tank, and I want to know the difference between it and a septic system. What are the main differences?
<bot>: The main difference between a septic tank and a septic system is that a septic tank is designed to treat wastewater from a residential or commercial building while a septic system is used for treating wastewater from multiple buildings on a single property. A septic tank has a smaller capacity than a septic system and is typically located underground near the building’s drainage field. A septic system usually consists of several tanks and pumps that move waste away from the home or business and into a drain field where bacteria break down organic material in the wastewater.
