The most common types of septic systems are gravity-based, drainfield systems, and leach field systems. Gravity-based systems rely on the natural slope of the land to move wastewater away from the home. Drainfield systems use a series of pipes that transport wastewater into an underground drainfield where it is allowed to soak into the soil. Leach field systems are similar to drainfields but they have more than one layer of soil to allow for better absorption of waste.
