Historically they helped keep drinking water free of contamination and thus greatly improved public health in cities with primitive sewerage systems.
Roman Aqueducts . The Roman aqueduct was a channel used to transport fresh water to highly populated areas. Aqueducts were amazing feats of engineering given the time period. Though earlier civilizations in Egypt and India also built aqueducts the Romans improved on the structure and built an extensive and complex network across their territories.
Aqueducts in Mesopotamia. The first sophisticated long-distance canal systems for water supply were constructed in the Assyrian Empire in the 9th century BCE and incorporated tunnels several kilometres in length. These engineering feats permitted the aqueducts to be constructed in a more direct line between source and outlet.
Aqueducts were used in ancient Greece ancient Egypt and ancient Rome. In modern times the largest aqueducts of all have been built in the United States to supply large cities. The simplest aqueducts are small ditches cut into the ea...
