How a septic tank and drain field work together
Wastewater leaves the home, solids settle in the tank, and clarified effluent moves to a soil absorption area (the drain field). When the field can no longer accept wastewater, backups, wet ground, or odors may appear—and major repair or replacement may be discussed after a professional evaluation.
