How much does it cost to install a septic tank and leach field in Litchfield County?

This is the full install for a new build or a property that never had a system. It includes the tank, the leach field, excavation, plumbing to the house, permits, and soil testing. Litchfield County's ledge and slow-draining soil often calls for an engineered leach field, which raises the price over a simple gravity system. Bigger homes need bigger fields. Soil and percolation tests come first — they decide what system your lot can actually support, so book those before budgeting the rest.
