What Yoakum County, TX's soil rates for a septic system
Somewhat limited
Soil across 70.1% of Yoakum County, TX rates "Somewhat limited" in USDA's septic-absorption-field interpretation.

Yoakum County, TX is 799.715 square miles with a population of 7,581.
What Yoakum County's reading doesn't cover
USDA's survey covers the whole of Yoakum County, TX at once, not any single address. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Yoakum County will actually do.
What a system would cost here
With 70.1% of Yoakum 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.
