Aqueduct

An **aqueduct** is a man-made channel that carries water from one place to another. Usually, they are used to supply water to cities and towns. They may also carry water for irrigation, or for hydroelectricity. Pipes, canals, tunnels, and bridges that serve this purpose are all called aqueducts. Some aqueducts carry a canal for boats and ships. The word “aqueduct” comes from the Latin words “aqua” (water) and “ducere” (to lead). Aqueducts have been used since ancient times.
