Septic services in St. Charles, South Carolina

Operators based within 12 miles of St. Charles

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 St. Charles

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of St. Charles — 31,998 acres across 36 soil map units — it rates 80.6% of the land very limited for that use and 18.8% somewhat limited, leaving 0.5% 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 St. Charles the leading one is depth to saturated zone on 93.7% of the mapped area, followed by seepage, bottom layer on 15.4%. In full:

Limiting featureShare of areaWhat it means on site
Depth to saturated zone93.7%A seasonal water table sits too close to the surface
Seepage, bottom layer15.4%The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered
Flooding11.1%The site floods often enough to matter
Slow water movement9%Water moves through the soil too slowly for a drain field to keep up
Filtering capacity3.3%The soil drains so fast it would not filter the effluent

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 99.4%.

The soils themselves

The named soils and land types that make up most of the ground around St. Charles. Goldsboro alone accounts for 20.9% 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 St. Charles (GNIS 2807067, 34.0806, -80.2249), 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: Lee County, South Carolina (2025-09-02), Sumter County, South Carolina (2025-09-02). 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.
