What Wright County, MN's soil rates for a septic system

Very limited

88.4% of Wright County, MN's surveyed soil comes back "Very limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field. This is the reading that pushes a project toward an engineered system rather than a conventional one, and it covers 88.4% of Wright County's land. Wright County, MN is 661.159 square miles with a population of 154,593.

What Wright County's reading doesn't cover

This is a countywide, area-weighted figure across every soil survey map unit in Wright County, MN - 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 Wright County will actually do.

What a system would cost here

With 88.4% of Wright 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.
