One of the methods of reducing water loss and leakage in a city's water distribution network is to divide the network into regional district metered areas (DMA) with the logic of "divide and conquer" and to monitor the network flow and pressure in these regions online. Hydraulic modeling and the structure of the network are taken into account in determining the DMA boundaries. While monitoring the isolated areas with zero pressure test, battery-powered data loggers that collect the measured data and send it once a day can be used, as well as control systems that send instant data online. In particular, considering the flow and pressure measurements made between 02:00 and 04:00, the unavoidable minimum night flow (MNF) of the relevant region is calculated. By comparing the unavoidable MNF flow rate and the actual flow rate, the infrastructure leakage index (ILI) is calculated together with other parameters. According to the ILI index visualized on the map, the regions are ranked from the worst to the best, and regions with significantly higher losses and thefts are determined, and the loss and theft are detected by performing night listening in these regions. If the DMA approach is not applied, it is practically not possible to search for all the missing-leakage in the city street by street.
