Statewide cost drivers here are high water tables and clay soils. Locally, karst geology may require special siting and extra testing. That is why a sand filter system in Kentucky 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.
