Septic soil in Saluda County, SC, by the numbers
Somewhat limited
Soil across 57.3% of Saluda County, SC rates "Somewhat limited" in USDA's septic-absorption-field interpretation.

Saluda County, SC is 453.213 square miles with a population of 19,452.
What Saluda County's reading doesn't cover
Saluda County's rating is an average across the whole county, not a promise about any one lot inside it. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Saluda County will actually do.
What a system would cost here
With 57.3% of Saluda County rating "Somewhat limited", a standard gravity system is not a safe assumption here. The engineered-system range, $10,000-$40,000 (mound or aerobic treatment), is the more realistic number to plan around, against $3,000-$8,000 for a conventional system on the rare lot that passes.
