To cope with the needs of increasing urban populations amidst negative impacts of climate change willrnrequire mainstreaming water demand management (WDM) in urban water management strategies for therncity of the future. There are a variety of options for WDM: urban water managers, engineers andrnplanners need to make correct choices of the most viable options that fit within the socio-cultural,rnpolitical, economic and environmental context. Ideally, these choices take into consideration the vision ofrnthe key city stakeholders and identified scenarios over the longer-term period. This paper describes arnsimple model developed as one of the outputs of the WDM research under the EU-sponsored SWITCHrnproject, to be used as a decision support tool by urban engineers, planners and managers, with no skillsrnin linear programming. The model uses a VENSIM modelling shell that is freely available on the internet.rnApplication of this tool will make it easier to mainstream WDM options in strategic planning processesrnfor the city of the future.
