Human: What are the benefits of a septic system versus a conventional system? Assistant: 
The primary benefit of a septic tank over a conventional system is that it uses biological processes to treat and filter wastewater, allowing for more efficient treatment of contaminants. This means less water is needed for flushing and fewer chemicals are needed for disinfection. Additionally, a septic tank can be designed to handle higher volumes of wastewater than a conventional system, making them more cost effective in larger homes or businesses.
