Septic Permits in Brown County: What Homeowners Need to Know

If you're planning any significant septic work in Brown County — whether it's a new installation, system replacement, or major repair — you'll need to navigate the county's permitting process. Here's what you need to know.

When Do You Need a Permit?

Brown County requires permits for:

• 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, but it's always best to check with your contractor.

The Permitting Process

Step 1: Soil Testing

Before any design work can begin, a certified soil tester must evaluate your property. They'll dig test pits, analyze soil types, and determine the percolation rate. This information determines what type of system your property can support.

Step 2: System Design

Based on the soil test results, a designer or engineer creates a system plan that meets Brown County's requirements. The design must account for your home's size, water usage, and the property's specific conditions.

Step 3: Permit Application

Your contractor submits the design, soil test results, and permit application to the Brown County Health Department or Sanitation Department. The county reviews the plans and issues the permit if everything meets code.

Step 4: Installation

Once permitted, installation can begin. Your contractor must follow the approved plans exactly.

Step 5: Final Inspection

After installation, a county inspector visits the site to verify everything was built according to the approved plans. Once approved, the system can go into service.

How Long Does It Take?

The entire permitting process typically takes 2 to 6 weeks, depending on soil tester availability, county review times, and the complexity of your project. Plan accordingly when scheduling your installation.
