May 20, 2022 · Designing of District metered areas (DMA) schemes is a key element in developing a technique for detecting and removing unreported leaks in a water distribution system (WDS) called active leakage control.

Apr 8, 2001 · After DMA • Leakage control is active. • Analysis of the DMA data prioritises leakage detection activities. DMA 04-08-01 Increased MNF

Jun 4, 2019 · During the low demand hours (night hours) the pressure within the DMA shoots up, causing increased leakage through the existing breaks and ruptures on pipeline. As the PRV reduces the pressure, the resulting leakage is also reduced.

Jan 5, 2021 · DMAs can reduce water loss several ways: By tracking total flow into a DMA and comparing with metered consumption, utilities can identify where both real and apparent loss is high. By tracking minimum nighttime flow in a DMA, …

Reduce water loss by monitoring water networks in real-time by implementing a Virtual District Metered Area (DMA) strategy. Get your white paper.

OPTIMIZING LEAK DETECTION WITH A VIRTUAL DMA Monitoring an Open Network with a vDMA Digital solutions are transforming leak detection by offering utilities new ways to identify and help prevent leaks through advanced technologies. Instead of creating a physical hydraulic control, a vDMA maintains more flexibility. In contrast to a traditional

Dec 7, 2015 · A common practice for leakage management is the sectorization of WDNs into small zones, called DMAs, by permanently closing isolation valves. This facilitates water companies to identify bursts and estimate leakage levels by …

Once established, a functional DMA can provide the information required to quickly identify unreported leaks and bursts as they occur. With proper metering, night flow patterns can be analysed to reveal night time use, background, and active leakage.

Jun 26, 2024 · Prioritisation of Active Leakage Control (ALC) and the types of activities required to reduce NRW can be inferred by the status of a DMA.
