<human>: I want to know how to create a septic tank.
<bot>: To create a septic tank, you will need to first determine the size of your tank and then dig a hole that is large enough for it to fit in. Next, install an outlet pipe from the tank to the drain field, which should be at least 200 feet away from any water source or wetland. Finally, fill the tank with soil, gravel, and other materials to help filter out waste. Make sure to check regularly for leaks and keep the tank clean.
