Water Demand Prognosis 2030 for the Hamburger Wasserwerke

In the Wasserbedarfsprognose 2030 project ('Water Demand Forecasting 2030'), ISOE and COOPERATIVE Darmstadt drew up a forecast for water demand in the area supplied by the Hamburg Waterworks (HWW).

Research approach

Scientists prepared a medium to long-term demand forecast covering the period up until 2030. For this they undertook spatially differentiated evaluations on the basis of a geographical information system (GIS). They also considered the social, technical and behaviour-based factors influencing water demand. The relevant groups of consumers and customers were taken into account in implementing the concept. To this end the team carried out empirical surveys amongst private and commercial customers as well as public facilities (e.g. hospitals, schools). The results were collated in the form of an integrated forecasting model.
