The document discusses Milan's experience with innovative water management solutions. It describes Milan's water distribution network and MM's smart water strategy, which includes analyzing water usage and losses, implementing advanced pressure management projects, installing smart metering infrastructure, detecting leaks, and developing customer services and decision support systems. The strategy aims to reduce energy consumption, water losses, and improve asset management through new technologies and optimized processes. An example project in Abbiategrasso reduced energy usage by 18% and leakage by 22% through real-time pressure control.
