Septic Inspection and POWTS Maintenance Reports in Wisconsin

Every septic system in Wisconsin has to be visually inspected at least once every 3 years, and the county tracks it. The inspection checks that the tank is sound and that wastewater is not ponding over the drainfield, and the result goes back to the county on a maintenance report.

State code lets a licensed plumber, a certified POWTS inspector, a certified septage operator or a registered POWTS maintainer do the inspection. Ask whether the inspector also pumps, whether the report is filed for you, and what happens if a problem turns up.
