Statewide cost drivers here are freeze depth, bedrock and older housing stock. Locally, shallow soils and bedrock are common; mound systems are frequent. That is why a sand filter system in Vermont can land well above or below the national range of $8,000–$16,000.

A sand filter treats effluent before it reaches the drain field, which helps on poor soil. It adds cost and requires scheduled maintenance.
