Septic System Installation in Wisconsin

A new or replacement septic system in Wisconsin starts with the soil. A certified soil tester digs and describes the site, usually with at least three soil excavations including a backhoe pit, and that report decides whether the property can take a conventional system, a mound, an at-grade bed or only a holding tank. A plumber designs the system from the soil test and applies for the county sanitary permit.

When you compare installers, ask who will do the soil test, who draws the plan and pulls the permit, and whether the same crew handles the excavation and the final inspection.
