Planning future investments in central water supply infrastructures today requires a thorough examination of possible changes that might be brought about by changing climatic and demographic conditions. For example, probable effects on the supply-side of water management encompass sea level rise and the resulting saltwater intrusion into the aquifers along the German coasts, changing river flow conditions, and an altered distribution of precipitation. On the demand side, greatly increased peak demands in summer, e.g. due to increased tourism on the coasts and an increased need for irrigation water in agriculture and cooling water in industry, will have to be assumed. Demographic change in the form of a prognosticated reduction in the population figures in Germany will influence these demand-side effects in many regions by reducing the average demand.

In the NAWAK project, local actors in selected model regions define the current problem situation for water supply. On the basis of these problem definitions, the scenarios built upon them and an analysis of their effects, planning instruments and regional adaptation strategies for water supply systems are to be developed.
