<human>: What is the difference between a septic system and a leach field?
<bot>: A septic tank is a large container that collects waste from a home. It is designed to filter out solid waste, such as food scraps and toilet paper, so that it can be safely disposed of in a nearby body of water. A leach field is a series of underground pipes that carry wastewater from the septic tank to a drainfield. The wastewater is then filtered through the soil, which helps reduce odor and pollution.
