New construction HRB Oberbobritzsch, Lot 5 - Relocation of raw water pipeline _ Civil engineering and pipeline construction:

In the course of the new construction of the Oberbobritzsch flood retention basin, an existing raw water pipe, as well as an emptying and a ventilation shaft have to be relocated. For the laying of the new raw water pipeline and the construction of the two shafts, clearing work is to be carried out in the area of the new route, as well as construction roads. The pipeline is partly laid in wooded areas in a construction corridor that must be adhered to. For the construction of the new drainage in the bank area of the Bobritzsch, the excavation pit is to be constructed in part by means of sheet piling and closed dewatering.
