Septic System Installation Permits
Permits for Installing a Septic System
Installation of all septic systems must be done according to an approved design from a licensed septic system designer. The installation permit from the department is issued after:
  • Soil verification by the County
  • Design requirements have been submitted and approved
  • Permit fee has been paid
  • Operating permit (when applicable) has been applied for

The installation permit is followed by a site inspection during the installation of the septic system. Once the system passes inspection, a certificate of compliance is issued for that system.
