Inspection lane
Complete the county application, obtain a 911 address, and submit an original site evaluation/soil analysis and septic design to the Freestone County Treasurer’s Office, Room 102. After approval, Authorization to Construct is issued and is valid for one year. The installer contacts the county inspector to schedule the final inspection; a Notice of Approval is issued when the system meets TCEQ and county requirements. Aerobic/secondary-treatment systems require a recorded affidavit and maintenance contract.
