The ancient Assyrians built artificial channels called aqueducts to bring water to their towns. One of them was built in 691, carrying water for 50 miles to Ninevah, capital of the ancient Assyrian Empire. 

The Romans built thousands of miles of aqueducts to bring water to their towns. Many of these were elevated iron, stone or wood structures, and were marvels of engineering. Eight aqueducts with a combined length of over 200 miles supplied Rome itself.

The largest Roman aqueduct, at Carthage in Tunisia, was 87 miles long and was built during the reign of Publius Aelius Hadrianus between 117 and 138.

Many Roman aqueducts are still standing, such as the one carried by the Pont du Gard at Nîmes in southern France, which was built about 8 BC.

In modern times, the largest aqueducts of all have been built in the United States to supply the country's biggest cities. The largest and most expensive is the Central Arizona Project , the largest and most expensive aqueduct constructed in the US. It stretches 336 miles from its source near Parker, Arizona to the metropolitan areas of Phoenix and Tucson.
