Abstract

The problem of water scarcity has been a main restricting factor for many large cities. How to realize the sustainable utilization of water resources through mod-ern technologies has become an important research subject for the development of big cities. Water resource problems in Beijing are composed of water shortage, the outstanding conflict between water supply and demand. In this paper the approach of an decision support system (DSS) for the joint optimal operation of different water sources such as surface water, ground water, recycled water and transferred water is presented. This decision support system will be developed in the frame of the joint Chinese–German project \“Toward Water-Scarcity Megalopolis’s Sustain-able Water Management System”. It is of significance for the sustainable develop-ment of economics and society in Beijing and the success of the Olympic Games in 2008. An indispensable requirement for such a DSS is a simulation model of the water resources and the water supply system. The simulation model for the region Beijing and the first results are presented here.

Because water is
