In July of 2010 we requested Loudon County Groundwater Protection to Permit an existing Septic system for an increase in size. I was told the fee for a Septic Permit has increased to $500 at that time. I belive the increase may be statewide. Thanks for your Inquiry.
I have put a website on here for you to check out. It answers all your building, well, and septic questions. I hope this helps you. If you need help in the futrure please let me know.
