Before you rely on this for one lot

Two lots a mile apart in Colorado 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 Colorado County, TX
