A septic system, also called an on-site wastewater treatment system, is a self-contained system used to treat wastewater, usually in rural areas.

It typically includes a septic tank, which holds wastewater from drains and allows solids to settle at the bottom, and a network of pipes that spread the liquid waste underground in a leach field. The system filters the wastewater through the soil to clean it before it can reach drinking water wells or surface water.

State and county laws require you to get a permit from the Department before building or fixing a septic system.
