What is the difference between a septic and a leach field?
assistant
A septic tank is a small underground chamber that contains bacteria to break down waste. The liquid from the tank flows into a drain field, which consists of pipes buried in the ground that carry the liquid away from the house. The drain field is designed to filter out solids before they reach the soil. A leach field is similar to a drain field, but it uses gravel instead of pipes to filter out solids.
