Roman Aqueducts

Ancient Rome had eleven major aqueducts, built between 312 B.C. (AquaAppia) and 226 A.D. (Aqua Alexandrina); the longest (Anio Novus) was 59 miles long. It has been calculated that in imperial times, when the city's population was well over a million, the distribution system was able to provide over one cubic meter of water per day for each inhabitant: more than we are accustomed to use nowadays.
