PLUMBING
One thing the Romans are well-known for is their plumbing, particularly the great aqueducts that carried water into towns – a major engineering feat – and huge sewers, such as the 6th-century BC Cloaca Maxima in Rome, that took waste out of the city. Aqueducts used gravity and the natural slope of the land to transport fresh water downhill from streams and lakes often located some distance away.
Aqueducts supplied farms, mines and (of course) the ubiquitous Roman baths. This is the Pont du Gard, which carried an aqueduct in southern France
