Construction
The 64-km- (39.5-mi-) long Aqua Anio (Anio Vetus, or "old Anio," so called after the Anio Novus is constructed) aqueduct, built largely below ground from stone, carries about 182,500,000 L (48,200,000 gal) of water a day to Rome from springs feeding the Anio River in the upper valleys of the Apennines. It is built from 272 bce to 269 bce with money obtained as a result of the defeat of Pyrrhus. See also 312 bce Construction; 144 bce Construction.
