This document summarizes a presentation given by Nicola Bazzurro of IREN Italy at the 2nd AQUAKNIGHT Conference in Aqaba, Jordan on May 21, 2014. The presentation discussed IREN's pilot project in Genoa, Italy to reduce non-revenue water. Key actions taken included installing pressure sensors and valves, leak detection and repairs. Results included a reduction in losses from 15 liters/second to 8 liters/second and pressure stabilization. Automatic meter reading was also implemented to better monitor usage and identify leaks or theft. A water balance calculation for the pilot area showed non-revenue water was reduced from 33% to 15% through these interventions.
