Introduction
In order to meet the water needs of its population, the city of Rome was eventually supplied with 11 aqueducts by 226 AD[citation needed], which were some of the city's greatest engineering achievements[citation needed].
Estimates of total water supplied in a day by all aqueducts vary from 520,000 m3 (140,000,000 US gal) to 1,127,220 m3 (297,780,000 US gal)[1]: 156-7 [2]: 347 , mostly sourced from the Aniene river and the Apennine Mountains[citation needed], serving a million citizens[citation needed]. Most of our information about Roman aqueducts come from statistics compiled in the late 1st century AD by Sextus Julius Frontinus, the Curator Aquarum[1]: 152 .
These estimates may not have considered water loss. Modern engineers have questioned the validity of these figures and measured Anio Novuslimestone deposits to estimate the average wetted perimeter and surface roughness corresponding to only 2/3 of the flow figure given below.[3]
