Abstract: The District Meter Areas (DMA) design is an innovative methodology of water networks management, based on the pressure patterns control and on the water flows monitoring, in order to reduce water losses and to optimize the water systems management. In the present paper the DMA design of the “Napoli Est” water distribution system (approximately 65. 000÷70. 000 customers), performed with the support of the Water Agency ARIN S. p. A., is discussed. After analysis of authorized consumption, by means of a monitoring campaign of water fluxes over the area, the system water balance was performed, showing significant water losses, as a consequence of high pressure patterns. District Meter Areas, therefore, were designed, and the corresponding hydraulic and water quality investigations and simulations were carried out. Six District Meter Areas were planned, assembling 14 intercepting valves and 9 pressure reducing valves to prevent the downstream pressure head from exceeding the set value, achieving a remarkable water saving, approximately equal to 34% of the physical losses.
