Urban water management is now constrained by rapid population growth, climate change and variability and their prediction uncertainty and above all by resource limitations. The ability of water systems to operate satisfactorily under these constraints is an important system characteristic. Performance criteria described in terms of mean yield and variance are not sufficient. Therefore risk-based performance criteria for urban water systems are proposed. These criteria are risk and reliability, resiliency and vulnerability. The quantitative estimation of these criteria and their implications for water resources planning are expected to improve the long term sustainability of water systems. The relatively new concept of integrated urban water management encourages water source diversification. This includes the use of rainwater, stormwater and treated wastewater. In this paper, multi-sourced urban water systems and their risk-based performance criteria have been proposed.
