Rehabilitation of large diameters in ongoing operation
Maintenance of sewer systems comprising large cross-sections (“large diameters”) is particularly challenging for the operator owing to the high potential of hazard in case of structural failure and the high financial expenditure for rehabilitation and reconstruction.
If such sewers require rehabilitation, the operation which means securing the runoff capacity is of crucial importance. The large flow rates involved require extensive measures for redirecting, pumping or lifting of the flow. From the experience made by engineering firm ZPP Ingenieure AG, two projects will be presented where...
