The Importance of Pressure Management in the Distribution Network within a DMA

Description

This paper addresses the problem of optimal pressure management in water distribution systems through the introduction and regulation of pressure reducing valves. Pressure management is one of the fundamental elements of a good flow management strategy development. The flow rate in water distribution networks is a function of pressure applied by pumps or by gravity. There is a physical relationship between flow rate and pressure, and there is also evidence that the frequency of new cracks is a function of pressure: System pressure management is an effective method to control leaks. This is usually achieved by dividing a large system into a small number of sections, i.e. the District Metering Area (DMA). The flow in DMA is monitored by installing bulk water meters at the inlet as well as at the borders, while the pressure is controlled with PRV. Water loss control is practiced by water utilities and end users using the DMA methodology. To understand the role played by both parties it is important to understand the responsibility for water loss.
