<human>: What is the difference between a septic tank and a septic field?
<bot>: The main difference between a septic tank and a septic field is that a septic tank is a sealed container that contains the waste from a home or building, while a septic field is an area where waste water is allowed to seep into the ground. A septic tank is usually made of concrete or plastic, while a septic field can be constructed with soil, gravel, or other materials.
