Where do I get a septic permit in Blount County?

Through the Blount County Department of Environmental Health in Maryville, (865) 681-9301, with services listed at blounttn.gov/299: septic permits and layouts for new systems, site evaluations by an environmentalist, and repair requests. Blount is a TDEC contract county, so this office runs the program and holds the records; they are not in the statewide TDEC database.

How much does a Blount County septic permit cost?

The county does not publish its septic fee schedule online, and no verified figure exists to print here. Call the Environmental Health office at (865) 681-9301 for current fees and processing times; the state framework allows up to 45 days from a complete application.

Does Blount County have a short-term rental septic rule like Sevier County?

No countywide short-term rental permit regime equivalent to Sevier County's was found in Blount County. What applies everywhere is the ordinary septic math: the soil evaluation sets the bedroom count a system supports, and a heavily used rental on a marginal system shows it first in the drainfield.

What makes Townsend septic sites different from the rest of the county?

Karst. Tuckaleechee Cove around Townsend sits on limestone with sinkholes, springs, and shallow rock windows, so site evaluations there focus on where effluent actually goes, not just slope. The foothill ridges toward Walland tell the more familiar thin-soil steep-grade story. Both can land a lot in the engineered lane.

Septic service in Blount County, Tennessee

Blount County covers the quieter half of the Smoky Mountain foothills: Maryville's growing edges, the Townsend "peaceful side" corridor, and cove-and-ridge country where municipal sewer ends and septic begins. Like its neighbor Sevier, Blount is a TDEC contract county that runs its own septic program through the Department of Environmental Health in Maryville, (865) 681-9301. Here is how the county works, what its terrain does to system design, and how to get a free quote.

The county office and what it does

Blount County Department of Environmental Health, Maryville, (865) 681-9301, with the county Health Department main line at (865) 983-4582. Its published services (blounttn.gov/299) cover the full septic lifecycle: septic permits and layouts for new subsurface sewage disposal systems, site evaluations performed by an environmentalist, and repair requests for existing systems. As a contract county, Blount issues its own permits under the statewide TDEC rules and keeps its own records, which means record pulls, installer verification, and parcel rulings all run through this office, not the state database. The state framework allows up to 45 days from a complete application; the county does not publish a fee schedule online, so get current fees directly from the office. Filing mechanics are in the permit process guide.

Two terrains, two septic stories

Blount's septic geography splits cleanly. Around Maryville, the county seat, subdivisions push into a foothill fringe where older conventional fields from the 1980s and 1990s are aging out, making drainfield repair and replacement the county's steady big-ticket work; replacements there are evaluated under today's TDEC Rule 0400-48-01 gates and regularly move to engineered designs. Around Townsend, the story changes underground: Tuckaleechee Cove is karst, limestone honeycombed with sinkholes and springs (Tuckaleechee Caverns is the tourist-visible proof), so site evaluations focus on shallow rock windows and where effluent travels, a groundwater-protection puzzle distinct from the thin-soil ridge story toward Walland and the Foothills Parkway. Both puzzles resolve the same way when conventional fails: the engineered systems, LPP, drip, mound, and ATU, explained in the engineered septic systems guide, designed and built through engineered septic system design.

No Sevier-style rental regime, same capacity math

Blount County has no countywide short-term rental permit program equivalent to Sevier County's, so cabin owners here deal only with the universal rule: the septic system's permitted bedroom count is the real capacity of the property. A Townsend rental cabin running full every weekend puts rental-scale load on whatever system the soil allowed, and the sizing conversation in cabin septic capacity and rental occupancy applies on this side of the mountains too, minus the Sevier permit overlay.

Getting your quote in Blount County

Describe the property and the project on the contact page, a Maryville drainfield showing its age, a Townsend build near the cove, a Walland ridge lot needing a design. The quote comes from an independent licensed local septic contractor who works Blount County and holds the TDEC credential the job requires. Sevier County owners have their own page here.

Verify your septic installer's Tennessee permit and credentials

Tennessee permits septic installers at the state level. Anyone who installs, alters, extends, or repairs a subsurface sewage disposal system (SSDS) must hold a current TDEC SSDS Installer Permit, earned by exam and renewed annually, with every permit expiring December 31 (tn.gov septic permits; cleanairtn.org). There are two classes: Conventional and Alternative. Engineered systems, low-pressure pipe (LPP), mound, drip, and aerobic treatment units, require the Alternative class. Whoever you hire should be a state-permitted septic system installer in the class your system needs.

One local wrinkle matters: Sevier and Blount are TDEC contract counties. They run septic permitting in-house, and their permit and installer records are not in the statewide database. Verify through the county office, not the state site: Sevier County Environmental Health, (865) 429-1766, or Blount County Environmental Health, (865) 681-9301 (blounttn.gov/299).

If the job is large, note that Tennessee separately requires a state contractor's license before bidding or contracting projects of $25,000 or more (Board for Licensing Contractors). That is an additional requirement on bigger engineered jobs, not the septic credential itself.

Three questions worth asking any installer

Is your TDEC SSDS Installer Permit current, and is it the Alternative class if my lot needs an engineered system?
Have you built this system type, LPP, drip, mound, or ATU, on steep or thin-soil lots in Sevier or Blount County before?
Will your bid include the county permit, the soil evaluation follow-through, and an itemized written estimate?

The checks above are exactly how to confirm the credentials of anyone who bids your job.

What it costs, and what happens after you send the form

What does the work cost in Blount County?: roughly $3,500 to $8,500 for a conventional install on flat, deep-soil ground; roughly $12,000 to $30,000 or more for an engineered system: mound, drip, LPP, or advanced treatment. Those are nationally reported ranges as of July 2026, HomeGuide and industry cost guides, and no published Sevier or Blount specific figure exists, so treat them as reported ranges to weigh a bid against, not quotes and not our prices.
How fast will someone get back to me?: Your request goes to a licensed local septic contractor who works your area, usually within about an hour during the day. They then contact you to look at the system and price the work on their own schedule.
What work is covered?: New installation, engineered system design, drainfield repair and replacement, inspections, permitting and soil evaluation, repair, and pumping.

Only a contractor standing on your property can price your actual system.
