The '''Cloaca Maxima''' was one of the world's earliest [[sewage]] systems. Constructed in [[ancient Rome]] in order to drain local marshes and remove the waste of one of the world's most populous [[city | cities]], it carried an effluent to the River [[Tiber]], which ran beside the city.

The name literally means '''Greatest Sewer'''. According to tradition it may have been initially constructed around [[600 BC]] under the orders of the [[monarch|king]] of Rome, [[Lucius Tarquinius Priscus]].<ref>[http://www.iath.virginia.edu/rome/Journal4Hopkins.pdf Waters of Rome Journal - 4 - Hopkins.indd<!-- Bot generated title -->]</ref>
This public work was largely achieved through the use of [[Etruscan civilization|Etruscan]] engineers and large amounts of semi-forced labour from the poorer classes of Roman citizens.
Although [[Livy]] describes it as being tunnelled out beneath Rome, he was writing a great deal after the event. From other writings and from the path that it takes, it seems more likely that it was originally an open drain, formed from streams from three of the neighbouring hills, that were channeled through the main [[Roman Forum|Forum]] and then on to the Tiber.<ref>[http://www.iath.virginia.edu/rome/Journal4Hopkins.pdf Waters of Rome Journal - 4 - Hopkins.indd<!-- Bot generated title -->]</ref> This open drain would then have been gradually built over, as building space within the city became more valuable. It is possible that both theories are correct, and certainly some of the lower parts of the system suggest that they would have been below ground level even at the time of the supposed construction.
==Aqueduct outfall==
The eleven [[aqueduct]]s which supplied water to Rome by the first century AD were finally channelled into the sewers after having supplied the many public baths such as the [[Baths of Diocletian]] and the [[Baths of Trajan]], the public fountains, imperial palaces and private houses. The continuous supply of running water helped to remove wastes and keep the sewers clear of obstructions. The best waters were reserved for potable drinking supplies, and the second quality waters would be used by the baths, the outfalls of which connected to the sewer network under the streets of the city. The aqueduct system was investigated by the general [[Frontinus]] at the end of the first century AD, who published his report on its state direct to the emperor [[Nerva]].
==Distribution system==
There were many branches off from the main sewer, but all seem to be 'official' drains that would have served public toilets, bath-houses and other public buildings. Private residences in Rome, even of the rich, would have relied on some sort of [[cess-pit]] arrangement for sewage.

The Cloaca Maxima was well maintained throughout the life of the [[Roman Empire]] and there is evidence to suggest it was still working long after the traditional fall of the Western Empire. In [[33 BC]] it is known to have received an inspection and overhaul from [[Marcus Vipsanius Agrippa| Agrippa]], and [[archaeology]] reveals several building styles and material from various ages, suggesting that the systems received regular attention. In more recent times, the remaining passages have been connected to the modern-day sewage system, mainly to cope with problems of [[backwash]] from the river.
The Cloaca Maxima was thought to be presided over by the goddess [[Cloacina]].

The Romans are recorded — the veracity of the accounts depending on the case — to have dragged the bodies of a number of people to the sewers rather than give them proper burial, among them the emperor [[Elagabalus]] and [[Saint Sebastian]]: the latter scene is the subject of a well-known artwork by [[Lodovico Carracci]].
The outfall of the Cloaca Maxima into the River Tiber is still visible today near the bridge Ponte Rotto, and near Ponte Palatino. There is a stairway going down to it visible next to the Basilica Julia at the Forum. (Some pictures [http://www.livius.org/a/italy/rome/cloaca/cloaca.html here], and [http://wings.buffalo.edu/AandL/Maecenas/rome/cloaca_maxima/ac991434.html here].) Some of it is also visible from the surface opposite the church of [[San Giorgio al Velabro]].
==The Empire==
The system of Roman sewers was much imitated throughout the [[Roman Empire]], especially when combined with copious supplies of water from [[Roman aqueducts]]. The sewer system in [[Eboracum]] — the modern-day English city of [[York]] — was especially impressive and still survives.
