Human: What are the benefits of using a septic system as opposed to a sewage system? Assistant: 
The primary benefit of using a septic system is that it requires significantly less maintenance than a sewage system. This means that you won’t have to worry about frequent pumping or draining, which can be expensive and time consuming. Additionally, septic systems use natural processes to treat wastewater, so they are generally more environmentally friendly than traditional sewer systems. Finally, because there is no direct connection between the septic tank and the drain field, there is less risk of contamination from raw sewage leaking into your water supply.
