Hancock County, OH's soil, for a septic absorption field

Very limited

In Hancock County, OH, 97.7% 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 - 97.7% of it sits in USDA's most-constrained bucket. Hancock County, OH is 531.324 square miles with a population of 75,016.

What Hancock County's reading doesn't cover

This is a countywide, area-weighted figure across every soil survey map unit in Hancock County, OH - never a reading for one specific parcel. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Hancock County will actually do.

What a system would cost here

With 97.7% of Hancock 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.
