Enhancing Planning in the Management Urban Water Systems to Increase Resilience

This Reprint presents recent contributions on strengthening the resilience of urban water systems facing climate and other disruptive events, highlighting the need for more adaptive and integrated planning approaches. The papers advance planning, risk management, and decision support by presenting methods for water security assessment, resource capacity evaluation, and utility-level decision making. Contributions include optimisation models, asset condition assessment techniques, and operational management frameworks that improve short- and medium-term planning. Innovative approaches to uncertainty integration and scenario building further support robust performance assessment under future variability. Efficiency and sustainability are addressed through water-energy-nutrient nexus perspectives, highlighting opportunities for energy savings and resource recovery. In parallel, alternative water sources, stormwater harvesting, and decentralised solutions are explored, providing insights into hybrid system configurations and scale-related trade-offs for resilience. Overall, this Reprint offers an integrated, up-to-date perspective, demonstrating how strategic planning, combined with practical tools, can enhance the sustainability and resilience of urban water services.
