What Bee County, TX's soil rates for a septic system
Very limited
Soil across 77.4% of Bee County, TX rates "Very limited" in USDA's septic-absorption-field interpretation. Expect the ground itself to work against a plain gravity system; USDA's strictest bucket alone covers 77.4% of the county. Bee County, TX is 880.239 square miles with a population of 31,226.
What Bee County's reading doesn't cover
USDA's survey covers the whole of Bee 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 Bee County will actually do.
What a system would cost here
With 77.4% of Bee County rating "Very 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.
Where this sits nationally
Nationally, Bee County, TX is the 2,164-most-constrained of 3,058 rated counties for septic soil. Within Texas alone it ranks 164 of 253.
