What's the difference between the two types of septic systems?
assistant
The primary difference between a septic tank and a septic system is that a septic tank collects and treats wastewater from a home’s plumbing fixtures, while a septic system combines the septic tank with an absorption field to treat wastewater. A septic tank typically has one or more compartments where wastewater accumulates before being treated by bacteria. In contrast, an absorption field is a series of trenches filled with gravel or stone which allows wastewater to pass through slowly into the ground.
