A water demand forecast for the service area of HAMBURG WASSER until the year 2045 is presented. The forecast approach is user group specific and includes spatial analysis. Water consumption data is intersected with geospatial information about aspects of social, economic and settlement structure. Major factors on the specific water demand within the user groups were identified and statistical correlations were used for the calculation of scenarios of water demand. The scenarios were developed according to official population and approved economic forecasts and complementary expert interviews. The forecast model has the form of a spreadsheet with analysis and forecasting functions. It integrates all data and provides a numerical as well as graphical representation of partial and overall results.

New technologies lead to a change of the motivations and functions of different actors as well as their constellations. A cooperation management allows to shape them. For the example of the HAMBURG WATER Cycle (HWC) and its first implementation it was investigated how the acting of the involved actors might be coordinated in such a way, that the optimal operation of the HWC results. Differentiated for the implementation phase and the operation phase possible relations between central actors have been identified regarding functions and cooperation. Ideal cooperation models have been developed for the Jenfelder Au site as well as for further applications of the HWC, domestic as well as abroad. The results are also of interests for other Novel Sanitary Systems; first generalizing hints for its use are given.
