Why Somerset County, MD isn't rated here

Unrated

Unlike most of the 3,144 counties on this site, Somerset County, MD has nothing to show: The dominant soil here (often already-developed urban land) carries no septic-suitability interpretation from USDA - too rare a gap to guess at. A local percolation test is the only way to know.

Before you rely on this for one lot

Somerset County's rating is an average across the whole county, not a promise about any one lot inside it. The real answer for one lot is still a site-specific perc test, running about $750-$1,850 (typically near $1,300).

Budgeting for a system in Somerset County, MD

With no SSURGO rating to go on, Somerset County has no county-level steer either way on system cost. Conventional systems typically run $3,000-$8,000; where the soil doesn't allow one, engineered alternatives run $10,000-$40,000. A perc test decides which range applies.
