What Lowndes County, MS's soil rates for a septic system

Very limited

92.3% of Lowndes County, MS's surveyed soil comes back "Very limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field.

What Lowndes County's reading doesn't cover

USDA's survey covers the whole of Lowndes County, MS 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 Lowndes County will actually do.

What a system would cost here

With 92.3% of Lowndes 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.
