Was a turnkey project had to do with installing each and every unit with the appropriate device that measures the water consumption, and the electricity consumption. As this was a prepaid system, we have installed a centralized database that monitors the consumption of all units, and has control over it. The centralized database is connected to the electricity and to the water meters through wireless connections, thus the bulk consumption can be determined and comparing it with what is received from the supplying company, Madinaty has all the information it needs to know what each unit uses, and what the public services use, and if there are any losses it can be easily noticed.
