It is generally accepted that the aqueduct S of Metz brought its water to Metz although the last kilometers of the conduit are missing. Its source was Les Bouillons north of Gorze. In Ars-sur-Moselle a huge aqueduct bridge crossed the Moselle river. In Ars the conduit was split in a castellum so that the crossing was made with two seperate channels to the second castellum in Jouy-aux-Arches on the W side of the river, where both channels were united and the water was conveyed direction Metz. The Ars castellum (E of the Moselle) also acted as a cleaning basin. Local water sources added their water in / near the castella on both sides of the Moselle river.
