2. Key Data TRANSITIONS TO THE URBAN SERVICES OF TOMORROW 30 partners from 11 countries: o 13 research institutes / universities o 7 small/medium-sized enterprises o 9 utilities / end-users o 1 international organisation Duration: May 2011 – April 2015 we are now in month 14 EC contribution: 6.98 million Euro Coordination: IWW Water Centre (Contact: d.schwesig@iww-online.de)

3. TRANSITIONS TO THE URBAN SERVICES OF TOMORROW Universities & research institutes Stakeholder Small/medium enterprises Utilities/end-users

4. Our main drivers and target group

7. Urban metabolism research aims to understand the overall flows and transitions of materials and energy within cities Might involve whole city scale or subsystems Towards sustainable urban systems through understanding the urban metabolism COMMON OBJECTIVE: Quantifying urban inputs and outputs, and understanding their sustainability impacts.

11. Conceptual UWCS metabolism model

12. Two TRUST metabolism models Both are dynamic models Evaluation of scenarios and intervention alternatives towards 2040 WaterMet 2 (TU Exeter) A distributed model Offers high spatial analysis resolution Full integration in the DSS WA5 DMM (NTNU) A lumped model related to urban ecology methods Offers no spatial analysis resolution Stand-alone Excel

13. Example: WaterMet 2 principles Water balance+ Technologies Quantitative metabolism Performance impacts

19. Objective is to identify impervious areas which can be disconnected from the sewer system in the most efficient and economical way Involves two steps; 1.Creation of a SUDS potential map which shows the spatial distribution of areas which are suitable for SUDS implementation. 2.Creation of “Disconnection Potential” maps which estimate the impervious areas which can be isolated from the sewer system and treated by SUDS. Evaluating the potential role of SUDS in reducing sewer flows in Oslo

21. Creation of disconnection potential maps

23. Water service suppliers frustrated by challenges of moving innovation from the lab to practical application. Major issues around who should hold the risk burden and provide funding. Whilst governance, regulation, and business models are important influences on innovation culture, innovation in these areas lags behind that in the more technical areas. Conducted during 2013 in Scotland, Oslo, Lisbon & Hamburg. Looked at customer ambitions for urban water services and service providers thinking about meeting those ambitions. Exposed a strong appetite for innovation amongst utilities as well as customer recognition that innovation is needed to address challenges. WA2 Workshops
