Harris County's SSURGO septic rating

Somewhat limited

Harris County, GA: USDA's soil survey calls 62% of the county "Somewhat limited" for a septic leach field.

For scale: 463.825 square miles and 36,929 people call Harris County home.

Before you rely on this for one lot

Two lots a mile apart in Harris County can carry different soil, even though they share one countywide rating. The real answer for one lot is still a site-specific perc test, running about $750-$1,850 (typically near $1,300).

Budgeting for a system in Harris County, GA

Conventional systems run $3,000-$8,000 where they pass; where they don't, engineered alternatives (mound or aerobic treatment, whichever the health department requires) run $10,000-$40,000 - budget toward the higher figure until a perc test says otherwise.
