The project ensured complex flood protection for Opole. The contract works included rebuilding of the river bed and inter-levee strip - 3 km in length We have also modernized additional hydraulic engineering installations. The works included installation of two bulkheads in Młynówka river and pumping out the water in order to clean the river bottom and conduct archeological research. As the heavy building equipment could not pass through narrow streets of the old town, we have used vessels and combined land and water transport. Some of the hydraulic engineering installations (e.g. weir) were built in late 19th and early 20th century. We have tried to restore them to their original condition. The water flowing through the installation is backlit, which makes the entire facility very attractive.
