Integrated Rehabilitation Management for Different Infrastructure Sectors

In Europe, our water distribution and wastewater collection networks are near the end of their assumed lifespan or will be in the coming years. Therefore, the main focus of urban water management is shifting from construction to rehabilitation. For state of the art rehabilitation management lots of different models to simulate the deterioration process are in use. These models depend strongly on the quality accuracy of the available data. Data is seldom available in high quality due to the only recently started information management of the operating companies. Therefore, a good data validation and reconstruction of the available data is essential for rehabilitation planning. Beside the deterioration also the interaction between the different infrastructure (gas, wastewater, water distribution, electric grids and road network) has to be taken into account as well as the changes in environmental factors (climate, population, etc.). These influences are integrated into a priority model to identify the “hot spots” for rehabilitation in the different networks.
