<human>: What are the best ways to create a septic system?
<bot>: The best way to create a septic system is to first determine the size and capacity of your system. You will then need to choose a location for the system that meets local regulations, such as proximity to water sources or existing sewer lines. After selecting a site, you will need to install a septic tank and drain field. To do this, you'll need to dig trenches in the ground, line them with PVC pipe, and fill them with gravel. Finally, connect the pipes to the septic tank, and pump out the waste from the tank every few weeks.
