Frequently asked questions about Septic Inspection Report
What does a septic inspection check?
A typical onsite wastewater treatment system inspection — commonly following the NAWT protocol — measures the scum and sludge layers in the tank, checks the tank structure and inlet/outlet baffles, tests any pump and high-water alarm, and inspects the drain field for signs of failure such as ponding, surfacing effluent, or odor.
How often should a septic tank be pumped?
A commonly cited rule of thumb is every 3 to 5 years, though the right interval depends on tank size, household size, and usage. Many inspectors recommend pumping once the combined scum and sludge depth approaches roughly a third of the tank's liquid depth, or when clearance from the outlet baffle drops below about 3 inches.
