SWANP: A Comprehensive Tool for Optimized Water Network Clustering

The creation of district metered areas (DMAs) in water distribution networks (WDNs) is a widely used technique that enables utilities to monitor systems by dividing them into subsystems. This approach effectively supports water balance, pressure management, and protection in case of contamination. The optimal design of DMA can be achieved with the use of advanced algorithms and tools, defining the partitioning of WDNs, which is structured in clustering and dividing phases. This research presents an application of SWANP (Smart Water Network Partitioning and Protection), a cutting-edge software collaboratively developed by researchers, an academic spin-off and water utilities. SWANP enables advanced hydraulic analysis using pressure-driven and demand-driven analyses to optimize WDNs. It offers various partitioning options through a user-friendly GIS-based interface, providing utilities with accessible, automated solutions for network management. In this paper, SWANP software is used to define a preliminary topological partitioning with reference to 38 WDNs, showing improvements in partitioning strategies also without hydraulic simulations. Results indicate cost savings on flow meters and valve installations, along with better control of water distribution systems. SWANP represents a major advancement in water network management, offering utilities innovative solutions for optimizing performance and ensuring sustainable, resilient urban infrastructure.
