Setting and maintenance in Common Duct

A utility tunnel is a subterranean space for wires, conduits, pipes, and other conveyances used in the delivery of utilities with enough room for a human to enter.
A common utility duct, sometimes called a common utility conduit, is any structure – above, on, or below ground – that carries more than two types of public utility lines. However, the phrase often refers specifically to underground tunnels.
