How did they get the water inside the Roman Colosseum?
The Flavian Amphitheatre was provided with water via the Aqua Claudia aqueduct and distributed through free-flowing canals, lead and terra-cotta pipes to storage reservoirs and then through lead pipes. A waste-water collection system discharged the waste into the drains or sewer system. The main outlet of the initial drainage system (Cloaca Maxima) was the Tiber River.
