Bailey County, TX's soil, for a septic absorption field
Somewhat limited
69.3% of Bailey County, TX's surveyed soil comes back "Somewhat limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field. It's a soil condition contractors work around routinely, with a bigger field or added fill, rather than one that forces an engineered system outright. Bailey County, TX is 826.972 square miles with a population of 7,031.
What Bailey County's reading doesn't cover
Bailey 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 Bailey County will actually do.
What a system would cost here
With 69.3% of Bailey 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.
