Septic Compass is a free service that connects homeowners with licensed local septic companies. We are not a contractor and do not perform septic work.
Most septic tanks sit with their lids 4 inches to 4 feet below the surface, with the tank body a bit deeper. Depth varies with terrain, freeze depth, and the original install. If your lids are buried deep, adding risers brings them to the surface for easy access.
