Abstract
The study presented in this thesis places its focus on urban water systems of the developing world, which are defned in terms of their component subsystems (the water supply subsystem, the stormwater subsystem, and the sanitation subsystem). These urban water systems
experience poor sustainable performance across their sanitation subsystems, across their stormwater subsystems lead to the pollution of their receiving water bodies. In these systems, there is an interaction between the constituent urban water subsystems, which drives the
overall sustainable performance of the urban water system.
The main objective of this study therefore is to generate insights into urban water management of urban water systems of the developing world by generating methods, methodologies and revelations to into their sustainable performance. The study started by introducing methods
and methodologies to utilize the limited readily available data of these systems to model their water end-use behaviour, to model their integrated behaviour, and also to simulate their integrated assessment when applied with numerous individually - applied urban water
interventions.
The study generated a novel methodology for evaluating the water end-use volumes of a developing world urban community, a novel methodology for the integrated modelling of the hydrology of water, stormwater and wastewater flow, and fnally a methodology for the
integrated assessment of the sustainable performance of urban water systems.
Utilising these methodologies, this study showed that of all the individually-applied 28 urban water interventions, none of them provided a signifcant positive sustainable performance across all the three urban water subsystems. In conclusion, it was recommended that to
generate an all-round sustainable performance of these urban water systems, the option of ‘multiple interventions in combination’ should be given consideration. It was further concluded that the use of ’multiple interventions’, not only improved the number of available urban water management options but also generated a higher overall sustainable performance
than individually - applied interventions.
