Description
Water Loss Management (WLM) by DIEHL Metering is designed to minimize water losses in distribution systems. The software is interoperable with several hardware and software solutions. The primary objective of WLM is to monitor and reduce non revenue water (NRW), in addition to providing support for the reporting of leak KPIs (e.g. NRW, real losses, ILI) for regulators (the EU Drinking Water Directive is mandatory by 2026). Other key objectives include continuous calibration, scheduling repairs based on volume loss and volume loss rate, and reducing the time from leak detection to repairs through continuous leak detection and localization.
The process is facilitated by a digital twin, which unifies multiple data pools from various departments (e.g. GIS, Hydraulics, Sensor Data, Annual Billing, and Damage Reports).
- The dashboard has been designed to present key performance indicators (KPIs) in a clear and accessible manner:
- DMA and their KPIs as well as their trends: NRW, night Flow and water loss
- Benchmarking between the different DMAs to determine which DMAs require urgent attention, allowing to schedule repairs accordingly
- Data Overview: Delivered/Consumed water and its Losses
- By clicking into an effected zone (red) the user drills down to the pipe with the leak in just minutes
To facilitate more precise and timely identification of leaks, following sub steps are performed:
- Following this, the modelling of the network can be undertaken. Both hydraulic and acoustic models can be implemented
- The subsequent damage reports, along with any anomalies that satisfy the calibration thresholds (e.g. large consumptions, flushing, pump switching, etc.), are utilized to automatically and continuously:
- Fit the deployed model to the real-world network
- Train the pattern recognition leak detection algorithm to best fit to the network’s data (Flow meters, Flow rate sensors, Temperature, Pressure sensors, acoustic sensors)
- The system is now operational and will automatically detect, track and localize leaks
