They built a system of aqueducts.

Aqueducts are constructions intended to transport water from one place to another one. They move water by gravity alone, as they have a slight downward gradient. Romans constructed aqueducts all over their territory, both during the Republic and during the Empire. They used them to bring fresh water to their cities, which was then used in public baths, latrines, fountains and private houses. Roman aqueducts proved to be extremely durable and reliable, with some still in use.
