The Blount County Septic Permit Process

4. A licensed installer completes the work to permit specifications.
5. The department inspects before any work is covered.

Blount County’s Certificate of Verification

Blount County offers a Certificate of Verification for situations where a septic system already exists and a new home is being connected to it. The local electrical authority may require this certificate in order to establish or re-establish power at a property. If you’re buying a home in Blount County served by an existing septic system, confirming whether a Certificate of Verification is needed before closing is worth a quick call to Development Services.

Repair Requests in Blount County

For repairs to existing systems, the Department of Environmental Health’s Environmentalist makes a site visit to determine the problem and draw a septic layout for the specific repair needed. Contact 865-681-9301 to initiate a repair request. Like all Tennessee counties, a permit is required before repair work begins — don’t allow an installer to start work without one.

Blount County’s Location and Terrain

Blount County sits directly south of Knox County, bordered by the Great Smoky Mountains National Park to the southeast. The county’s terrain varies dramatically — from relatively flat areas near Maryville and Alcoa to steep, rocky Appalachian terrain as you move toward the park. Properties near the mountains are more likely to encounter the thin, rocky soil conditions that drive East Tennessee’s higher alternative system costs. Properties in Maryville and Alcoa’s more developed areas often have better soil depth and more predictable site conditions.

Blount County’s proximity to the Smokies also means many properties have private wells alongside septic systems — setback requirements between wells and septic components under TDEC’s rules are particularly important to understand for these properties.

Septic Records in Blount County

Septic permit records in Blount County are accessible through Development Services’ dedicated records request process. Contact 865-681-9301 or visit the Blount County Development Services office to request permit history, as-built drawings, or inspection records for a property.
