Septic Permits in Outagamie County: What Homeowners Need to Know
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)
- System modifications or expansions
Routine pumping and minor repairs generally don't require permits.
The Permitting Process
Step 1: Soil Testing
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.
