they were built in the last century and they were used to filter water for rome
The Roman aqueducts were water conduits which took water form the mountains to the cities. Most of them were underground pipes. Some of them were on top of bridgework. This was done when there was a need to cross a valley or it was needed to keep the conduit at a gradient, as the Romans relied on gravity to make the water move.
Roman aqueducts were built whenever they were needed. The first aqueduct was built in 312 BC and it was called the Aqua Appia. Others followed whenever and wherever they were needed.
The Roman aqueducts were built over a period of 500 years, with the first being built in 321 BCE. This was the Aqua Appia, which carried water to the City of Rome from a source about 16.4 km away.
