Where were the materials from to build the roman aqueducts?

Answer 1

The Roman aqueducts, the actual water carrying pipes, were made of ceramic. This material was more durable than the lead that was used for domestic piping. The external structure of the above ground aqueducts was made mostly of a combination of concrete and brick.

Answer 2

Most of the length of the Roman aqueducts consisted of flat-bottomed, arch-section underground water conduits 05.5 or 1 metre below ground. They were made of brick-faced (Roman) concrete. Conduits above ground were slab-topped. The spinghouses which collected the spring water were made in stone or concrete. The water was carried down the slopes with a system of inverted siphons. The pipes of the siphons were made of soldered lead which were sometimes placed in concrete encasements or stone sleeves. Occasionally they were made of stone or ceramic and sealed with lead. The conduits were placed on bridgework when they needed to cross a valley of when they needed to be kept at a gradient in a plain to keep the water flowing. These were made with masonry or concrete or, when they were not easily available locally, bricks.
