Communal latrines were in use throughout the Roman Empire, feeding into either primary or secondary sewers, from the 1st through 5th centuries AD. A very well-preserved example are the latrines at Housesteads on Hadrian's Wall in Britain. Such toilets did not flush in the modern sense, but had a continuous stream of running water to wash away waste. With the fall of the Western Roman Empire, these communal toilet systems fell into disuse in Western Europe, though continued in the Eastern Byzantine Roman Empire, with records of toilet pipes being renewed, and sewers repaired.
