This page lists ancient Roman aqueducts in the city of Rome.

Introduction[edit]

In order to meet the massive water needs of its huge population, the city of Rome itself was supplied with 11 aqueducts. Their combined capacity was capable of supplying at least 1,127,220 cubic meters (nearly 300 million gallons) of water to the city each day from the Apennine mountains. Detailed statistics for the city's aqueducts were logged around 97 by Sextus Julius Frontinus, the curator aquarum (superintendent of the aqueducts) for Rome during the reign of Nerva. Less information is known about aqueducts built after Frontinus.
