Septic services in Williamston, South Carolina

Operators based within 12 miles of Williamston

Listed by where the business is, not by who it says it serves. Every operator here was on the SCDES Onsite Wastewater Contractors list on the date its record shows, and the address it is placed by comes from that same list, so this is a checkable claim rather than a service-area promise. A South Carolina licence is issued by the state, not by a county, so operators further out can work here too; these are simply the ones closest to you.

Soil and septic suitability around Williamston

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Williamston — 32,002 acres across 49 soil map units — it rates 22.7% of the land very limited for that use and 75.5% 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 Williamston the leading one is slope on 22.5% of the mapped area, followed by depth to saturated zone on 9.8%. In full:

Limiting featureShare of areaWhat it means on site
Slope22.5%The ground is too steep for a conventional field
Depth to saturated zone9.8%A seasonal water table sits too close to the surface
Flooding5.2%The site floods often enough to matter
Seepage, bottom layer4.4%The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered
Depth to bedrock4.3%Bedrock is too shallow to fit a trench above it

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 98.2%.

The soils themselves

The named soils and land types that make up most of the ground around Williamston. Cecil alone accounts for 54.1% of it.

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

Area of interest: a 4-mile radius around the USGS Geographic Names centre point for Williamston (GNIS 2406888, 34.6191, -82.4804), 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. Survey areas: Anderson County, South Carolina (2025-08-29), Greenville County, South Carolina (2025-08-29). Retrieved 2026-09-18.

This is a survey, not an evaluation of your lot. The permit decision rests on the site evaluation SCDES carries out for the specific parcel.
