UVQ: Modelling the Movement of Water and Contaminants through the Total Urban Water Cycle

This paper presents the water and contaminant daily simulation model of the total water cycle, called UVQ. The model has been developed to provide a means for rapidly assessing conventional and non-conventional approaches to providing water supply, stormwater and wastewater services to urban allotments, neighbourhoods and catchments. The model is placed in the context of other such models developed internationally through a brief literature review. This is followed by a description of the model and a case study, which is used to illustrate the utility of the model. UVQ is an effective tool for assessing the impacts of urban development options on the total water cycle, as well as the performance of a wide range of non-conventional demand and supply side management techniques. It compliments other aspects of an environmental assessment of options, along with more traditional aspects such as infrastructure costing.
