Septic services in Dukedom, Tennessee

Operators based within 12 miles of Dukedom

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.

Soil and septic suitability around Dukedom

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Dukedom — 32,015 acres across 46 soil map units — it rates 84.9% of the land very limited for that use and 9.3% somewhat limited, leaving 1.2% with no rated limitation.

What the limitation actually is

A rating on its own tells you nothing you can act on. The reasons do, and around Dukedom the leading one is depth to saturated zone on 72.9% of the mapped area, followed by flooding on 18.9%. In full:

Limiting featureShare of areaWhat it means on site
Depth to saturated zone72.9%A seasonal water table sits too close to the surface
Flooding18.9%The site floods often enough to matter
Slope13.1%The ground is too steep for a conventional field
Seepage, bottom layer12%The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered
Slow water movement3.1%Water moves through the soil too slowly for a drain field to keep up

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 94.2%.

The soils themselves

The named soils and land types that make up most of the ground around Dukedom. Loring alone accounts for 31.8% of it.

“None in profile” means SSURGO records no bedrock or other restrictive layer within the depth it describes, not that none exists.

What that means if you are building or repairing here

A seasonal water table

Some of the ground around Dukedom 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 Dukedom (GNIS 1283116, 36.5023, -88.7151), 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.
