Evaluation Methods of Survival Capacity Oriented Investment Strategies of Drain and Sewer Systems by the Use of Damage-Specific Aging Models

Operation, maintenance and rehabilitation of drain and sewer systems are among the most complex of communal assignments. On the one hand, depending on the size of the community, the systems are of great length and, on the other hand, because of their age structure, they mirror all the development states so that, today, they consist of very heterogeneous networks, with numerous cross sections and dimensions, pipe materials, pipe joints, types of bedding, principles of construction, types of lines, drainage methods, etc. To comprehend the interplay and linkages for the individual sewers and the whole network in order to work out an economical optimized cost and investment strategy for cleaning, inspection and rehabilitation methods is one of the most demanding tasks of the network operator. In order to solve these tasks in a proper manner, conditions, substance acquisitions, assessments and forecasts must be balanced in order to formulate a sensible Whole Life Costing (WLC) concept. In this paper, a concept of this type currently in a test phase in Germany is presented.
