Septic rules that apply in Smithville

  • Permits. Property owners and installers need a TDEC construction permit before building, altering, extending or repairing a system, and a modification permit when adding bedrooms or building over part of an existing system. Source.
  • Selling a home. We found no Tennessee rule requiring a septic inspection at sale, but TDEC issues Inspection Letters documenting an existing system's status, which owners, realtors, lenders and buyers routinely request (the rule fee for inspecting an existing system is $200), and it will test well water for bacteria. Source.
  • Aerobic systems. Advanced treatment systems (aerobic units) must be TDEC-approved NSF Standard 40 Class I models, and the owner must operate and maintain them forever, an obligation that runs with the land. Source.
  • Tank size. A 3-bedroom house in Tennessee needs a tank of at least 900 gallons. Sizes by bedrooms.

Nationally, septic pumping runs $250 to $1,250 with an average around $427 (HomeGuide, 2026). Rural Tennessee markets typically land toward the middle of that range. Tank size, accessibility, and time since last pump-out drive the price.
