The Besigheim lock system is located in the direction of flow of the Neckar at the lower end of an approximately 0.6 km long lock channel and consists of a double lock on the right bank. The associated three-span Besigheim weir and the hydroelectric power station are up the Neckar in the Altneckar (Neckar-km 136.6) on the left bank. The gates of the lock system survive in the head from one piece, the lower main two-part lift gates. The upper gates on the head also serve as flood barriers . The gates were last renewed in 1992, while the drives and electrical engineering are from the construction period. In particular, the two-part lower main gates are now very prone to failure. Furthermore, the concrete wall of the lock has remained unchanged since the construction time. The lock stands on around 960 piles in very poor subsoil. At least four geological faults in the subsoil were already known at the time of construction. The most recent excavation drillings have not revealed a clearly recognizable rock horizon down to a depth of 54 m.

Construction project

In order to be able to operate the lock system safely in the future, at least one chamber, preferably the right (landside) chamber, must be completely repaired. The necessary measures include the new construction of a lower head with the necessary replacement of the lifting gates with mitred gates , the replacement of all drives, the electrical engineering and, in large parts, a planned concrete renovation. Depending on the result of a subsoil report to be drawn up by the BAW, a subsoil upgrading for stability is required, the scope of which has not yet been determined.

The start of construction is scheduled for the end of 2018, the expected construction time is two years.
