Umm Qais
East of Adraha was a bridge. The remains of the bridge now can be found on the ground of the new Al Saad Dam located at the eastern suburbs of Dera'a. After a junction point with a side channel from the Muzayrib lake, the underground aqueduct begins. Three water systems have been found near Gadara (Umm Qais). The first and second were built with qanat technology, and the third was built as a channel along a street. It is believed that all three systems were used, but each at a different period.
