Definition
A septic system is your personal wastewater treatment plant—it breaks down waste in a tank and filters it into the ground through a drain field. It requires your active participation to stay healthy.

Septic systems treat wastewater through bacterial action in the tank and soil absorption in the drain field. Regular pumping (every 3-5 years) maintains system function. System failure—backing up into the home or surfacing in the yard—is expensive and unpleasant. Common problems include soil saturation from poor drainage, system age/inadequate sizing, or root intrusion. Inspectors examine system location, access, pumping history, and drain field condition. Septic inspections may require pumping to verify tank volume.
Pro Tip
Know your septic system's location, age, and pumping history. Maintain regular pumping schedules—it's the cheapest insurance against catastrophic failure.
Example
A septic system inspection revealed the tank hadn't been pumped in 8 years and contained excessive sludge. Pumping and treatment cleared the system; the homeowner established regular pumping every 4 years to prevent future problems.
