Water reuse schemes in urban water system are assessed in this paper against a number of hydraulic performance indicators. A city metabolism model, WaterMet2, is used to evaluate the performance of water reuse schemes. A multi-objective evolutionary algorithm is employed to identify Pareto optimal solutions for the following three objectives: resilience, reliability and total cost. The demonstration of the suggested approach on a real-world case study show the importance of using the resilience index for determining the appropriate schemes. The results suggest, in the case analysed here, the rainwater-harvesting scheme plays a significant role for improvement of resilience index.

Quantitative Assessment of Future Sustainability Performance in Urban Water Services using WaterMet² Behzadian, Kourosh; Kapelan, Zoran; Morley, Mark S.; Govindarajan, Venkatesh; Brattebø, H.; Sægrov, S.; Nazari, S.; Jamshid Mousavi, S. (IWA Publishing, 2015)Urban water services are likely to face challenges in the future, mainly due to population growth, climate change, increasing urbanization and ageing infrastructure. These factors are expected to impose significant strains ...
Behzadian, Kourosh; Kapelan, Zoran (Elsevier, 2015-04-27)This paper presents a new quantitative model called ‘WaterMet2’ for the metabolism based assessment of the integrated urban water system (UWS) performance. WaterMet2 quantifies a number of UWS flows/fluxes (e.g. water and ...
