Urban water distribution networks (WDNs) are essential infrastructures that ensure the continuous supply of clean and safe water to communities. Due to population growth, climate variability, and aging infrastructure, improving operational efficiency and minimizing losses have become critical objectives for water utilities. Among the major challenges faced by modern WDNs, leakages represent a significant source of inefficiency; in Italy, networks lose approximately 42% of the treated water before it reaches consumers. Such losses impose substantial economic costs, reduce system resilience, and hinder the sustainable management of water resources. This thesis work involved the development of a hydraulic digital model and the evaluation of algorithms for leakage monitoring in two municipalities in the Province of Cuneo, Piedmont, Italy: Cavallermaggiore and Marene.
