The repair of the dike is part of the flood damage remediation of the June flood 2013 and the flood protection concept of the state of Saxony-Anhalt. THP's scope of work comprised service phases 1 to 8 according to HOAI. Steinle Bau GmbH, based in Oschatz, was commissioned with the construction work.
The elevation of the left-hand flood protection plant on the White Elster is being carried out on the existing route by installing a projecting sheet pile wall. The route is crossed by a large number of cables and lines. During construction, finding the actual location of the cables and lines as well as the execution planning that had to be updated as a result was a major challenge for the construction company and THP. This was solved together, to the complete satisfaction of the client and within the construction time.
At dike kilometer 1+065, the Hasselbach, a 2nd order watercourse, crosses the flood protection system. In extreme cases, the Weiße Elster backs up into the Hasselbach and leads to flooding of the industrial area located in the hinterland or the Zeitz city area. To prevent the backwater, a new barrier structure was therefore built to close the gap in the dike. The barrier structure is a statically independent reinforced concrete construction (trough profile) with a rectangular opening as a culvert. A sliding contactor made of stainless steel serves as the closure, which is manually operated with a mobile drive key. The hydraulic steel structure was manufactured and installed by Metallbau-Wasserkraft Onnen Krieger GmbH & Co. KG.
After the start of the construction work in May 2020, the acceptance took place after a one-year construction period, which resulted in costs of approx. 3.5 million Euros. After the execution of the remaining pipelines, the new flood protection facilities were handed over to the LHW in the summer of 2021. Thus, another building block for flood protection in the city of Zeitz and in particular for the Südzucker Group's most traditional sugar factory was completed. Sugar has been extracted from beets at the site for over 150 years. The new plant, which was built in 1993 on the site of the existing plant dating back to 1858, is one of the largest new sugar factories to be built in the new federal states following reunification. With its production, the plant can cover the average annual demand of 4 to 5 million consumers.
