During recent years, techniques and legislation for decentralized storm-water management have advanced all over the world. However, decentralized storm-water management systems are still under-utilized and acceptance among citizens and professionals is still lacking. Yet management of this issue will be essential for the sustainable development of cities in the future. Thus acceptance of the systems must be improved. The main question that needs to be answered is how can sustainable storm-water management be integrated with urban design in order to create safe, liveable, sustainable, and attractive cities?
Water Sensitive Urban Design, developed by the Hafen City University of Hamburg, provides an overview of a Water Sensitive Urban Design approach and creates principles for a successful strategy focused on the topics: Water Sensitivity, Aesthetics, Functionality, Usability, Public Perception and Acceptance, as well as Integrative Planning. It furthermore presents an international selection of case studies ranging from small scale (site level) up to large scale (city level), demonstrating the WSUD principles in the context of the temperate climates.
