The Aldingen barrage is one of 27 barrages on the navigable Neckar between Plochingen and the confluence with the Rhine and consists of a lock, a hydroelectric power station and a weir system. The barrage is spanned by a box girder bridge.

At almost 80 years old, the weir in Aldingen has already exceeded its calculated lifespan and therefore requires fundamental repairs or a new replacement. In addition, the construction of a fish ladder as well as measures for fish protection and downstream fish migration must be implemented at the Aldingen barrage in order to fulfil the obligations under the EU WFD.

In July 2021, Tractebel Hydroprojekt was awarded the contract to plan the following projects:

  • Modernisation (renovation or replacement) of the weir system,
  • Construction of a fish ladder
  • Measures for fish protection and fish descent
  • Replacement construction of the weir and lock bridge
