The challenge of establishing integrated urban water management (IUWM) lies in the nature of and interaction between various subjects. Following on from integrated water resources management (IWRM), IUWM is structured as a holistic approach. Environmental issues, institutional functions and instruments for planning and management form the basis for integrated urban water management. This paper presents the development of a methodology for identifying, bundling and prioritising measures, taking into account resource orientation and cost-efficiency analysis. The approach is applied to the City of Darkhan, Mongolia’s second largest city, which serves as a model area for Central Asia. The model region has to cope with an extreme continental climate, the livestock agriculture of the nomads, nutrient losses in cultivated agricultural areas, trans-boundary impacts on Lake Baikal and the potential for conflicts through mining activities. Settlement structures are heterogeneous, the cultural imprint of post-socialist structures is still present and the technical infrastructure can be described as decrepit. The planning approach presented here consists of the integrated delineation and bundling of measures, along with the creation of an adapted database structure and a decision-making process for prioritisation. The form of the resulting implementation plan will depend on the actual costs and duration.
