<human>: What are the advantages of a septic system?
<bot>: The main advantage of a septic system is that it is a more environmentally friendly way to treat wastewater. It does not produce any harmful byproducts, and can be used in areas where traditional sewer systems may not be feasible. Additionally, a septic tank can help reduce water pollution as it filters out contaminants before they enter the environment. Finally, a septic tank helps keep your home’s groundwater cleaner by removing impurities from the wastewater.
