2BG: Black, blue and green - Integrated infrastructure planning as key to sustainable urban water systems

Project Details


Quality in life is possible only within the frames of a healthy and sustainable environment. The ambition of 2BG is to contribute to global sustainable development by demonstrating novel ways for cities to interact with Earth’s water: from today’s »consume-and-discharge« to an integrated and recycling mode of interaction. To close the urban water cycle we need to focus on all assets of water in the city; from drinking water to ecosystem services and from industrial functions to water’s aesthetic and socio-cultural dimensions. The project aims to develop concepts, methods and tools for changing the prevailing sewer based discharge systems into self-sustaining and climate-change adapted solutions, based on infiltration of storm and wastewater at the source, combined with appropriate control of water quality and extended reuse. Thus, hydrological models that operate at and link between different sizes of affected catchments, ranging from single roof tops to groundwater aquifers, will be developed; risks related to pollutants being transported within the urban water flows will be described and mitigation options evaluated and developed further. The potential of water management techniques to make a positive contribution to the urban landscape will be elaborated. As inter-professional approaches are needed for realizing the suggested changes in urban water systems, new spatial IT-tools and planning methods will be developed for support of collaboration between urban planners, engineers and landscape architects, as well as suitable cost-benefit tools and economic instruments to support decision makers. These will be tested and evaluated in case studies. Finally, to make the project results operational within the Danish water resource base, concepts for exchange and transfer of knowledge will be developed and tested in pilot programs, aiming at both the national market and the global markets in rapidly developing cities. The "Forest and Landscape" unit of Copenhagen University, Faculty of Life Sciences is overall project coordinator.
