Solution Details
Pipeline Leakage Detection and DMA District Metering System Solution
The Pipeline Leakage Detection and DMA District Metering System Solution is the most effective approach for water utilities to tackle Non-Revenue Water (NRW) and achieve significant leakage control. This comprehensive system enables precise monitoring and management of water distribution networks to meet stringent targets, such as China's national goal to reduce urban water network leakage below 9% by 2025.
Policy Background and NRW Challenge
Non-revenue water (NRW) is a persistent global challenge for water utilities, representing significant financial and resource loss. The International Water Association (IWA) endorses District Metered Area (DMA) management as the cornerstone methodology for systematic leakage control.
Governments are implementing strict policies, with China setting a clear national target to reduce urban water network leakage rates to below 9% by 2025, driving widespread adoption of advanced DMA solutions.
Core Technical Highlights
Intelligent MNF Analysis for Leakage Assessment
Ecolor's DMA metering system utilizes high-precision LGF electromagnetic flowmeters paired with Hero V9 RTU terminals to provide real-time, accurate monitoring of boundary flow and pressure. This forms the critical data foundation for all subsequent analysis.
The system's built-in Minimum Night Flow (MNF) algorithms automatically establish a baseline night consumption profile for each DMA. By continuously comparing real-time data against this baseline, the system can evaluate leakage volumes with high accuracy.
Precision Leak Location Technology
The solution employs hierarchical DMA analysis to systematically narrow down leak locations. This multi-stage diagnostic process can pinpoint suspected leak areas to within a 50-meter radius, dramatically reducing the time and cost associated with traditional leak detection surveys.
Key Application Scenarios
Urban Water Utility NRW Reduction
Core application for municipal water suppliers to systematically reduce water loss and improve operational efficiency.
