The planning has been completed and the necessary permits for the rehabilitation have been obtained. In October 2017, rehabilitation work began on the Marchfeld dam in two construction lots. In March 2018 (Rußbach dams) and August 2018 (Schönauer backwater dam), construction work was started in two further construction lots. In spring 2019, the two sections of the improved flood protection Vienna, the Stopfenreuth spillway and the Witzelsdorf backwater dam are already scheduled to follow.

Finally, the main construction work for the functional completion of the flood protection dams will be carried out by the end of 2020. After completion of the remaining work, the rehabilitation of the dam system according to the current state of the art is expected to be fully completed by the end of 2023.
