If you're planning any significant septic work in Outagamie County, here's what you need to know about the permitting process.

When Do You Need a Permit?

  • New septic system installations
  • System replacements
  • Major repairs (drain field replacement, tank replacement)

Routine pumping and minor repairs generally don't require permits.

The Permitting Process

A certified soil tester evaluates your property, digs test pits, and determines the percolation rate.

Step 2: System Design

A designer creates a system plan that meets Outagamie County's requirements.

Step 3: Permit Application

Your contractor submits the design and application to the Outagamie County Health Department.

Step 4: Installation

Once permitted, installation can begin following the approved plans.

Step 5: Final Inspection

A county inspector verifies everything was built according to the approved plans.

How Long Does It Take?

The process typically takes 2 to 6 weeks. Winnebago County has similar requirements.
