Operators based within 12 miles of Great Falls

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 Great Falls

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Great Falls — 32,002 acres across 87 soil map units — it rates 68.8% of the land very limited for that use and 23.6% somewhat limited, and almost none with no limitation at all.

• Very limited · 68.8%
• Somewhat limited · 23.6%
• Not rated · 7.6%

What the limitation actually is

A rating on its own tells you nothing you can act on. The reasons do, and around Great Falls the leading one is slope on 44.3% of the mapped area, followed by depth to bedrock on 23.8%. In full:

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 92.4%.

The soils themselves

The named soils and land types that make up most of the ground around Great Falls. Cecil alone accounts for 14.5% 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 Great Falls (GNIS 2406608, 34.5721, -80.9053), 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: Chester County, South Carolina (2025-08-29), Fairfield County, South Carolina (2025-08-29), Lancaster 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.
