Howard County, NE's soil, for a septic absorption field
Very limited
In Howard County, NE, 80% of the surveyed land carries a "Very limited" rating for a standard septic drain field. Practically, that rules out a simple gravity system for most of the county - 80% of it sits in USDA's most-constrained bucket. Howard County, NE is 569.27 square miles with a population of 6,572.
What Howard County's reading doesn't cover
Two lots a mile apart in Howard County can carry different soil, even though they share one countywide rating. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Howard County will actually do.
What a system would cost here
With 80% of Howard 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.
