Griggs County, ND Septic Rating

Griggs County, ND: the USDA septic-suitability picture

Very limited

USDA puts Griggs County, ND at "Very limited" for septic absorption fields, the dominant reading across 65.5% of the county's soil. That reading means a conventional system is a poor bet here - it's already USDA's strictest "very limited" bucket, not a partial constraint. The county spans 709 square miles, home to 2,227 people.

What this number does and doesn't tell you

This is a countywide, area-weighted figure across every soil survey map unit in Griggs County, ND - never a reading for one specific parcel. Budget $750-$1,850 for a real perc test on any specific parcel - that's the only figure a permit application accepts.

Griggs County: conventional vs. engineered cost

65.5% of Griggs County carrying a "Very limited" reading changes the realistic budget here. Conventional systems run $3,000-$8,000 where they pass; where they don't, engineered alternatives (mound or aerobic treatment, whichever the health department requires) run $10,000-$40,000 - budget toward the higher figure until a perc test says otherwise.
