"Aqueduct, (Latin: aqua + ducere, “to lead water”) man-made conduit for carrying water. In a restricted sense, aqueducts are structures used to conduct a water stream across a hollow or valley. In modern engineering, however, aqueduct refers to a system of pipes, ditches, canals, tunnels, and supporting structures used to convey water from its source to its main distribution point. Such systems generally are used to supply cities and agricultural lands with water. Aqueducts have been important particularly for the development of areas with limited direct access to freshwater sources. Historically, aqueducts helped keep drinking water free of human waste and other contamination and thus greatly improved public health in cities with primitive sewerage systems."
