A new rear basin protects around twenty places on the Wipper from flooding. Tractebel Hydroprojekt planned and supervised the dam structure, which was opened after six years of construction.
Many villages along the Wipper suffer from flood events. Losses in the double-digit millions are the result. After six years of construction, the new retention basins remedy the problem. Together with the member of the Bundestag Torsten Schweiger, the member of the state parliament André Schröder, the district councillor in the district of Mansfeld-Südharz, Dr. Angelika Klein, Sangerhausen's mayor Sven Strauß, the mayor of Wippra, Monika Rauhut, and the chairman of the board of directors of the dam company Michael Janssen, Saxony-Anhalt's Environment Minister Prof. Dr. Claudia Dalbert cut the opening band.
Construction and construction supervision
At the upper reaches of the Wipper, directly above the village of Wippra in the district of Mansfeld-Südharz, the controlled flood retention basin was created, which is passable for fish and other living beings. From May 2013, Tractebel Hydroprojekt was the general planner for this ambitious dam construction project and supervised the construction. The hydraulic engineering experts optimized the present design planning and prepared the execution and tender planning. They also worked out the safety proofs and planned the rock securing. The team of experts also took over the geotechnical construction supervision including the metrological monitoring. With the handover of the test jam program and the provisional operating regulations, it clears the way for the commissioning of the basin.
"Now a 100-year flood event of the Wipper can be completely withheld and thus the damage potential of such flooding for 21 villages in the lower reaches can be decisively defused. Flood protection in the region has been sustainably strengthened," underlined Environment Minister Dalbert at the opening ceremony.
