Scott County's SSURGO septic rating
Very limited
USDA puts Scott County, KS at "Very limited" for septic absorption fields, the dominant reading across 74.9% of the county's soil.

For scale: 717.585 square miles and 4,914 people call Scott County home.
Before you rely on this for one lot
USDA's survey covers the whole of Scott County, KS at once, not any single address. 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 Scott County, KS
Scott County's soil reading pushes the likely outcome toward an engineered system rather than a conventional one. 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.
