Septic services in Lenox, Tennessee

Operators based within 12 miles of Lenox

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 Lenox

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Lenox — 32,012 acres across 53 soil map units — it rates 82% of the land very limited for that use and 9.6% somewhat limited, and almost none with no limitation at all.

What the limitation actually is

A rating on its own tells you nothing you can act on. The reasons do, and around Lenox the leading one is depth to saturated zone on 69.6% of the mapped area, followed by flooding on 64.9%. In full:

Limiting featureShare of areaWhat it means on site
Depth to saturated zone69.6%A seasonal water table sits too close to the surface
Flooding64.9%The site floods often enough to matter
Slow water movement39%Water moves through the soil too slowly for a drain field to keep up
Slope18.8%The ground is too steep for a conventional field
Seepage, bottom layer11.1%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 91.6%.

The soils themselves

The named soils and land types that make up most of the ground around Lenox. Memphis alone accounts for 21.2% 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 Lenox 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.

Ground that floods

The bottomland around Lenox floods, and a septic system in it fails in the least pleasant way available. Flooding lifts tanks, backfills fields with silt, and pushes untreated effluent to the surface where people walk. The practical consequence is straightforward and it is about siting rather than design: the field goes out of the floodplain, even when that puts it a long way from the house, and a lot whose only buildable ground is bottomland may not support a system at all.

Slow-draining soil

The ground around Lenox 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.

Area of interest: a 4-mile radius around the USGS Geographic Names centre point for Lenox (GNIS 1291021, 36.0892, -89.4984), 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.

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.
