How often should a septic system be maintained in Wisconsin?
Conventional systems typically need pumping every 3 years. Advanced systems may need quarterly or annual maintenance depending on design.
Is a POWTS maintainer the same as a septic pumper?
Not exactly. POWTS maintainers perform inspections and routine maintenance. Septage pumping and hauling may require a separate DNR license.
Who is responsible for septic system maintenance?
The property owner is responsible. Counties track maintenance compliance through their POWTS maintenance program.
