Influence of Future Water Demand Patterns on the District Metered Areas Design and Benefits Yielded by Pressure Management

This paper addresses the influence of different daily patterns of nodal water demands on the District Metered Areas (DMA) design and benefits yielded by pressure management. The objective is to compare the total cost investment and the maximum benefits from leakage reduction for given nodal demands, by implementing the pressure management at the district metered areas entry points. The methodology used (Gomes, 2011; Gomes et al., 2012a) follows the water losses management international best practices and uses a pressure driven simulation model to predict the network hydraulic behaviour under different patterns of nodal demands and pressure conditions.
