Stair renovation headwater of the river power plants Altenwörth and Greifenstein

In the Altenwörth and Greifenstein reservoirs, damaged and necessary stairways and gauges are rehabilitated while damaged and no longer necessary stairways and gauges are deconstructed. The stairways and gauges in this area date back to the time when the power station was built in the 1980s. This is being done on the basis of an internally and externally coordinated concept and a requirements survey.

A requirements analysis was carried out and the construction contract was awarded to STRABAG AG. Construction will follow from June onwards and should be completed in autumn. No major obstruction of the Danube bicycle route is expected during construction, with the exception in the area of the Greifenstein power plant, tailwater left bank. A diversion and information concept has been drawn up for this purpose. In autumn 2024, 15 staircases were already removed and replaced with corresponding prefabricated parts. The replacement of a further 15 or so stairways is planned for 2025. This will improve the landside waterway infrastructure in the long term.
