Databases and hydraulic model as a basis for reduction water losses in water supply sistems

Water losses in water supply systems currently represent one of the major global challenges. Benchmarking data indicates that only a small number of countries maintain water losses within acceptable levels, while the majority of nations and their utility companies report losses exceeding 40%. Water utilities and the systems they manage face significant challenges in resource management, particularly when it comes to reducing non-revenue water. Losses in water distribution networks pose not only technical and economic issues, but also sustainability and responsible water resource management concerns. Databases and hydraulic models play a key role in the efficient management of water supply systems. Databases enable detailed mapping and a comprehensive understanding of the assets being managed, while hydraulic models allow for network simulation and analysis, helping to identify critical points and potential loss areas. By establishing a detailed and centralized database of the water supply system and implementing a hydraulic model, utilities can conduct in-depth network analysis and segmentation. This includes the creation of DMA (District Metered Areas), virtual DMAs, and pressure management zones - all of which are essential tools in the effort to reduce water losses. These approaches facilitate continuous system monitoring, consumption analysis, and timely interventions during routine maintenance, thereby supporting a systematic reduction of losses.
