The ancient Romans also had a complex system of aqueducts, which were used to transport water across long distances. The first Roman aqueduct was built in 312 BCE. The eleventh and final ancient Roman aqueduct was built in 226 CE. Put together, the Roman aqueducts extended over 450 kilometers, but less than seventy kilometers of this was above ground and supported by arches.
Sanitation in ancient Rome
The management and maintenance involved in keeping the aqueducts flowing is well described by Frontinus, a general appointed by the emperor Nerva as water commissioner toward the end of the first century AD. He described his work on the distribution system in De aquaeductu published at the end of the first century AD. When first appointed, he surveyed and mapped the entire system, and strove to investigate the many abuses of the water supply, such as the act of tapping into pipes illegally. He also systematized aqueduct maintenance with gangs of specially trained workmen. He also tried to separate the supply, so that the best-quality water went to drinking and cooking, while second-quality water flowed to the fountains, baths, and, finally, sewers.
The system in Rome was copied in all provincial towns and cities of the Roman Empire, and even down to villas that could afford the plumbing. Roman citizens came to expect high standards of hygiene, and the army was also well provided with latrines and bath houses, or thermae. Aqueducts were used everywhere in the empire not just to supply drinking water for private houses but to supply other needs such as irrigation, public fountains, and thermae. Indeed, many of the provincial aqueducts survive in working order to the present day, although modernized and updated. Of the eleven ancient aqueducts serving Rome, eight of them entered Rome close to each other on the Esquiline Hill. Also, the first aqueduct was the Aqua Appia built in 312 BC by the censor Appius. Other aqueducts of importance to Roman sanitation was the Aqua Marcia built between 144-140 BC, which provided large amounts of quality water to Rome. One Aqueduct with some major importance to Rome was Traiana, which tapped from the clear springs of the northern and western slopes above lake Bracciano. It is said that the “Romans fully appreciated the importance of plentiful and wholesome supply of water, for domestic purposes to health of the Community. It was stated by Amulree that for 441 years after the building of Rome, it depended on water from the Tiber for drinking and other domestic purposes, but in 312 BC Appius Claudius Crassus provide Rome with water from the Springs of the Alban hills and brought to consumers by the means of Aqueducts. The Amulree notes state that this practice is in line with the teachings of Hippocrates: that stagnant water should be refused, not the spring water from the hills or rain water.
