Statewide cost drivers here are clay soils and deep frost. Locally, rocky ground in the Ozarks can add significant excavation cost. That is why a sand filter system in Missouri 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.
