Septic Soil Testing and Perc Tests in Wisconsin

Soil testing comes first for any new septic system in Wisconsin: a certified soil tester evaluates the soil on the site before the system can be designed. The report decides what can be built: a conventional in-ground system, a pressure or at-grade system, a mound, or, where nothing else works, a holding tank.

The companies on this page say they do soil evaluations or perc tests, or name a certified soil tester on staff. Soil tester is a state credential issued by the Department of Safety and Professional Services. Ask for the tester's certification, how the soil pits are dug, and whether the report is ready for the sanitary permit application.
