Human: What are the benefits of a septic system? Assistant: 
The primary benefit of a septic tank is that it allows waste to be treated before being released into the environment. This helps protect groundwater and reduces pollution. In addition, a septic tank can help reduce odors in the surrounding area, as well as providing an aerobic environment for bacteria to break down organic material. Finally, a properly functioning septic system can also help prevent the spread of disease by removing harmful pathogens from the wastewater.
