Septic services in Cottageville, South Carolina

Operators based within 12 miles of Cottageville

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 Cottageville

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Cottageville — 31,990 acres across 38 soil map units — it rates 96.7% of the land very limited for that use and 3.3% 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 Cottageville the leading one is depth to saturated zone on 98.2% of the mapped area, followed by slow water movement on 37.2%. In full:

Limiting featureShare of areaWhat it means on site
Depth to saturated zone98.2%A seasonal water table sits too close to the surface
Slow water movement37.2%Water moves through the soil too slowly for a drain field to keep up
Seepage, bottom layer20.5%The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered
Ponding14.5%Water stands on the surface
Flooding11.2%The site floods often enough to matter

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 100%.

The soils themselves

The named soils and land types that make up most of the ground around Cottageville. Ogeechee alone accounts for 11.1% 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 Cottageville (GNIS 2406317, 32.9362, -80.4803), 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 an evaluation of your lot. The permit decision rests on the site evaluation SCDES carries out for the specific parcel.
