Septic services in Lenoir City, Tennessee

Operators based within 12 miles of Lenoir City

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 Lenoir City

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Lenoir City — 32,010 acres across 127 soil map units — it rates 54.2% of the land very limited for that use and 29.6% 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 Lenoir City the leading one is slope on 39.3% of the mapped area, followed by depth to bedrock on 9.3%. In full:

Limiting featureShare of areaWhat it means on site
Slope39.3%The ground is too steep for a conventional field
Depth to bedrock9.3%Bedrock is too shallow to fit a trench above it
Flooding8.3%The site floods often enough to matter
Slow water movement8.1%Water moves through the soil too slowly for a drain field to keep up
Seepage, bottom layer4.3%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 83.8%.

The soils themselves

The named soils and land types that make up most of the ground around Lenoir City. Dewey alone accounts for 31.7% 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

Steep ground

A drain field has to be close to level. Effluent is distributed along a trench by gravity or by pump, and on a grade it runs to the low end, overloads it, and surfaces there. Around Lenoir City enough of the ground is steep that field placement tends to decide house placement rather than the other way round — the usable field area is often a bench or a shoulder some distance from the best building site, and the connection between them is a cost. It is worth knowing which part of a lot is the field before you fall in love with a view.

Area of interest: a 4-mile radius around the USGS Geographic Names centre point for Lenoir City (GNIS 1291019, 35.7973, -84.2560), 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.
