Reducing the amount of unmetered water at the level of the localities operated by Aparegio GORJ SA, in order to optimise the operation of the water and waste water infrastructure and to streamline the process of drinking water distribution and digitisation of the data obtained from the field. In order to actively reduce the amount of unmetered water and to improve network operation, it is fundamental to sectorise it by installing as many measuring and control devices as possible (flow meters, pressure sensors, automatic valves, meters) and digitisation of the obtained data (datalogs for data acquisition and data interpretation software).
