Abstract: Management of existing water supply networks can be substantially improved by the definition of District Meter Areas (DMAs). District metering represents, indeed, one of the most efficient techniques for water losses detection and pressure management of water supply systems, but its implementation in an existing water network may compromise its performance, since the minimization of metering sections usually implies the reduction of network redundancy. In the practical applications, the DMA design is, generally, based on empirical approaches or on restricted field experiences that may hardly be applied on great water supply system with high level of branching and looping. In this work a Decision Support System (DSS) is proposed to identify the optimal position of the sectioned pipes to define the permanent DMAs using graph theory principles. The DSS is applied to Anytown network and the results confirm the effectiveness of proposed methodology, which is verified by comparing different DMA designs with several statistics, hydraulics and energetic performance indicators.
