List of aqueducts in the city of Rome

This is a list of ancient Roman aqueducts in the city of Rome.

Introduction

In order to meet the water needs of its population, the city of Rome was eventually supplied with 11 aqueducts by 226 AD, which were some of the city's greatest engineering achievements. Estimates of total water supplied in a day by all aqueducts vary from to , mostly sourced from the Aniene river and the Apennine Mountains, serving a million citizens. Most of our information about Roman aqueducts come from statistics compiled in the late 1st century AD by Sextus Julius Frontinus, the Curator Aquarum.

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.
