Certified Septic Inspection & Mandatory State Testing

Stay compliant and avoid heavy fines with our professional Wisconsin state septic testing. We specialize in the mandatory inspections required every 3 years for homeowners in Waukesha County and the Lake Country area.

We believe in "maintenance as needed," not "maintenance by guess." Using a Sludge Judge, we provide a scientific measurement of your tank's levels. Because sludge buildup is a natural process, pumping isn't always the answer. Our precise data ensures you only pay for a pump-out when your system truly requires it—saving you money while keeping your system in peak condition and fully compliant with state regulations.
