The ancient Romans constructed numerous aqueducts (Latin aquaeductūs, sing. aquaeductus) to supply water to cities and industrial sites. These aqueducts were amongst the greatest engineering feats of the ancient world, and set a standard not equaled for over a thousand years after the fall of Rome. Many cities still maintain and use the ancient aqueducts for their water supply even today.

The Romans typically built aqueducts to serve any large city in their empire. The city of Rome itself, being the largest city, had the largest concentration of aqueducts, with water being supplied by eleven aqueducts constructed over a period of 500 years.

The combined length of the aqueducts in the city of Rome is estimated between 420 and a little over 500km. However, only 29 miles (47 km) were above ground, as most Roman aqueducts ran beneath the surface of the ground. Building underground helped to keep the water free from disease (the carcasses of animals would not be able to get into the aqueduct) and helped protect the aqueducts from enemy attack. The longest Roman aqueduct was that of Constantinople (Mango 1995). "The known system is at least two and half times the length of the longest recorded Roman aqueducts at Carthage and Cologne, but perhaps more significantly it represents one of the most outstanding surveying achievements of any pre-industrial society". Perhaps the second longest, the Zaghouan Aqueduct, is 57.5 miles (92.5 km) in length. It was built in the 2nd century to supply Carthage (in modern Tunisia). The 2nd century is the period from 101 - 200 in accordance with the Julian calendar in the Christian Era. ...

The arcades, a series of arches, popularly shown to depict an aqueduct, should not be confused with the aqueduct itself. These arches, sometimes on several tiers, together with tunnels, were constructed to maintain the pitch of the aqueduct, and the flow of water, over irregular terrain, for the long course to its destination.

Roman aqueducts were extremely sophisticated constructions. They were built to remarkably fine tolerances, and of a technological standard that had a gradient (for example, at the Pont du Gard) of only 34 cm per km (3.4:10,000), descending only 17 m vertically in its entire length of 50 km (31 miles). Powered entirely by gravity, they could carry large amounts of water very efficiently. The Pont du Gard could transport up to 20,000 cubic meters — nearly 6 million gallons — a day, and the combined aqueducts of the city of Rome supplied around 1 million cubic meters (300 million gallons) a day. These figures were however functions of the catchment hydrology and aqueduct regulation technique as shown by recent studies. (For comparison the maximum value represents a value 25% larger than the present water supply of the city of Bangalore, with a population of 6 million). Sometimes, where depressions deeper than 50 m had to be crossed, gravity pressurized pipelines called inverted siphons were used to force water uphill (although they almost always used venter bridges as well). Modern hydraulic engineers use similar techniques to enable sewers and water pipes to cross depressions. Gravity is a force of attraction that acts between bodies that have mass. ...

In addition to the expertise needed to build them, Roman aqueducts required a comprehensive system of regular maintenance to repair accidental breaches, to clear the lines of debris, and to remove buildup of chemicals such as calcium carbonate that naturally occur in the water.

Construction Many tools were used in the construction of Roman aqueducts, one example being the chorobates. The chorobates was used to level terrain before construction. It was a wooden object supported by four legs with a flat board on top in which was engraved a half circle. When used the half circle was filled with water and the angle at which there was no water was measured. Another tool used in the construction of the aqueduct was the groma. Gromas were used to measure right angles. A groma consisted of stones hanging off four sticks perpendicular to one another. Distant objects could be marked out against the station of the stones in a horizontal plane. A chorobates (Greek χωÏοβἀτης from khÅros; place + -batos, going) was a kind of level used in classical antiquity. ...
Groma Definition The Groma or gruma (altered from Greek gnomon γνὠμων indicator, possibly through Etruscan) was the principal Roman surveying instrument. ...
Decline of the aqueducts With the fall of the Roman Empire, although some of the aqueducts were deliberately cut by enemies, many more fell into disuse from the lack of an organized maintenance system. The decline of functioning aqueducts to deliver water had a large practical impact in reducing the population of the city of Rome from its high of over 1 million in ancient times to considerably less in the medieval era, reaching as low as 30,000. This article is about the historiography of the decline of the Roman Empire. ...
