Listed by where the business is, not by who it says it serves. Every operator here holds a current state permit, and the address it is placed by comes from the state's own published list — so this is a checkable claim rather than a service-area promise. A Tennessee installer permit is valid statewide, so operators further out can work here too; these are simply the ones closest to you.

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Flintville — 32,005 acres across 29 soil map units — it rates 69.3% of the land very limited for that use and 27.1% somewhat limited, and almost none with no limitation at all.
A rating on its own tells you nothing you can act on. The reasons do, and around Flintville the leading one is slow water movement on 51.3% of the mapped area, followed by depth to saturated zone on 48.4%. In full:
| Limiting feature | Share of area | What it means on site |
|---|---|---|
| Slow water movement | 51.3% | Water moves through the soil too slowly for a drain field to keep up |
| Depth to saturated zone | 48.4% | A seasonal water table sits too close to the surface |
| Slope | 16% | The ground is too steep for a conventional field |
| Depth to bedrock | 12.2% | Bedrock is too shallow to fit a trench above it |
| Seepage, bottom layer | 9.6% | The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered |
Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 96.4%.
The named soils and land types that make up most of the ground around Flintville. Ironcity alone accounts for 18.3% of it.
| Soil or land type | Share | Drainage | Slope | Depth to bedrock | Septic rating |
|---|---|---|---|---|---|
| Ironcity | 18.3% | Well drained | 2 to 12% | None in profile | Somewhat limited |
| Dickson | 16.1% | Moderately well drained | 0 to 12% | 72 in | Very limited |
| Mountview | 15.1% | Moderately well drained | 2 to 20% | None in profile | Very limited |
| Taft | 11.1% | Somewhat poorly drained | 0 to 5% | None in profile | Very limited |
| Hawthorne | 7.8% | Somewhat excessively drained | 5 to 50% | 26 in | Very limited |
“None in profile” means SSURGO records no bedrock or other restrictive layer within the depth it describes, not that none exists.
The ground around Flintville holds water. Tennessee measures this as an absorption rate in minutes per inch, and slow soil does not fail a site so much as enlarge it: the slower the rate, the more trench length the same household needs, and past a point a conventional field stops being approvable at all. A slow site is normally still buildable on a low-pressure pipe or drip design, and that is the point at which the installer list matters, because most licence holders in Tennessee are not endorsed for either.
Some of the ground around Flintville carries a water table that rises close to the surface for part of the year and is nowhere to be seen for the rest of it. A field built into saturated soil does not treat effluent and does not drain, and the soil does not have to be wet on the day it is looked at for that to be true — the evidence is in the profile, as mottling and grey colours, which is one of the reasons the work is done by someone trained to read a soil pit rather than by timing water in a hole in August.
Area of interest: a 4-mile radius around the USGS Geographic Names centre point for Flintville (GNIS 1284492, 35.0626, -86.4197), chosen because five of this state's communities are unincorporated and have no boundary to use, and because the lots that need a septic permit are in the ring around a town rather than inside it. Soil from USDA-NRCS Soil Data Access, SSURGO interpretation “ENG - Septic Tank Absorption Fields”, area-weighted by mapped acreage and by each component's share of its map unit.

This is a survey, not a soil map for your lot. A permit needs a high-intensity map of the specific parcel, produced by a TDEC-approved soil consultant — see soil map vs perc test.
