aqueduct

This term evokes a sense of monumental engineering and historical permanence, often associated with the architectural grandeur of the Roman Empire. It suggests a deliberate, large-scale modification of the landscape to overcome geographical barriers for the sake of urban survival or agricultural productivity. While modern piping systems perform the same function, the word specifically implies a structured conduit, often elevated on arches or carved into rock, distinguishing it from simple ditches or underground sewers.
