Analysis of MNF and FAVAD Model for Leakage Characterization by Exploiting Smart-Metered Data: The Case of the Gorino Ferrarese (FE-Italy) District

Leakages in water distribution systems have great economic and environmental impacts are a major issue for utilities. In this work, the balance Minimum Night Flow (MNF) method evaluating amount of loss, as well power Fixed Variable Area Discharge (FAVAD) equations analyzing relationship between leakage pressure, were applied to fully monitored District Metered (DMA) located Gorino Ferrarese (FE, Italy). Time series (a) consumption each user, (b) DMA inflow, (c) pressure at inlet point with 5 min time step. The results an analysis carried out by exploiting collected highlighted that: application MNF based on literature values can lead significant inaccuracies presence users irregular consumption, estimation parameters FAVAD is highly affected amounts types observed data used.
