Integrated modeling has become an urgent issue of urban drainage and wastewater treatment planning. The scope of integrated modeling, system boundaries and disciplines to be involved are addressed in view of future developments and new paradigms in urban drainage, demanding the inclusion of the full urban water cycle. A system analysis is demonstrated to identify relevant sub-systems and components, processes and interactions within the urban water system. The permissibility to exclude subsystems or neglect interactions is evaluated. Integrated modeling of urban water system is characterized as an ambitious task in regard to system complexity, heterogeneous scales and interface problems. The methodical status quo is characterized in preliminary approaches towards integrated modeling. It is concluded that it does not seem promising to create and apply one entity model for the scope of integrated urban water modeling. Instead, the development of adequate and efficient IT frameworks is identified as the key issue of integrated modeling. Harmonizing interfaces to facilitate the linking of existing models is presented as the objective of a European research project HarmonIT and the U.S. EPA Multimedia Integrated Modeling System project MIMS.
