This master thesis analyses previously identified risks and chosen elements, among them sustainability targets, of urban water services providers that take part in the project ‘Nachhaltigkeitscontrolling in der Siedlungswasserwirtschaft’ (Sustainability Controlling for Urban Water Systems), by taking into account their relation to each other. In order to analyse those risks which constitute a netting of effects, a Network Analysis, a Cross-Impact-Matrix, and qualitative System Dynamics were chosen. The objective of this treatise was to determine the state of the netting structure and to characterize its elements. Furthermore, the paper intends to test and verify the suitability of the chosen methods, and to identify starting points to combat the risks by applying the characterized elements. The result of the analysis is that the methods show the importance of certain elements under different points of view, so that their function and the risk situation of the sustainability targets in the netting structure can be revealed. The respectively identified functions indicate areas in which influence can be exerted on the netting of effects through manipulation of certain elements. This exertion of influence can be translated into mitigation and/or adaptation strategies to face sustainability risks.
