STRATEGIES FOR REDUCING LOSSES IN WATER SUPPLY SYSTEMS AND ENSURING EFFICIENT USE OF RESOURCES

This study explores effective strategies for reducing water losses and enhancing resource efficiency in urban water supply systems. Non-revenue water (NRW), resulting from physical leaks, metering inaccuracies, and unauthorized consumption, poses significant operational, financial, and environmental challenges for utilities worldwide. The research reviews international case studies, best practices, and methodological frameworks, emphasizing integrated approaches that combine pressure management, district metered areas (DMAs), active leakage control, infrastructure rehabilitation, smart metering, and digital monitoring systems. Findings indicate that coordinated technical and managerial interventions lead to substantial reductions in NRW, lower energy consumption, and improved utility performance.
