List of aqueducts in the city of Rome
This page lists ancient Roman aqueducts in the city of Rome.
In order to meet the massive water needs of its huge population, the city of Rome was supplied with 11 aqueducts. Their combined capacity was capable of supplying at least 1,127,000 cubic metres (nearly 300 million gallons) of water to the city each day mostly from the Anio and the Apennine Mountains, serving a million citizens. Detailed statistics for the city's aqueducts were logged around 97 AD 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.
These estimates may not have considered water loss. Modern engineers have questioned the validity of these figures and measured Anio Novus limestone deposits to estimate the average wetted perimeter and surface roughness corresponding to only 2/3 of the flow figure given below.
