Mobile app detailWater loss & leak detection · Network management
We turn escaping water into a signal.
LeakExpert is a system for water loss and leak detection in municipal drinking-water networks: it finds physical loss by acoustic listening, measures flow and pressure continuously, and manages the whole field on one platform. More than 25 years of field experience, built into a mobile app and a web panel.
The basis of the method
Minimum night flow is the measure of an invisible leak.
Consumption stops at night. The higher the minimum night flow measured at the reservoir outlet, the more leakage is running below ground. By international consensus, roughly 70% of that volume is physical loss and 30% is apparent loss. We turn that difference into a number without any excavation.
Measurement and analysis servicesOne system
From the field to management, one seamless platform.
Web and mobile work as one: the field crew records on a phone, the office manages from the web panel, and the API connects both sides and the GSM flow meters in real time.
Management panel
Leaflet-based interactive map, main and route drawing, multi-layer view, Excel/Word report output, quotation module, per-municipality role management.
Web panel detailData infrastructure
Hono + PostgreSQL core, cloud photo archive, live sync over WebSocket, GSM ultrasonic flow meter integration.
API infrastructure detailField services
From measurement to a repair plan.
Acoustic leak detection
Day and night acoustic listening and correlation locate the leak point below ground to the metre. Non-destructive.
Flow measurement & NRW
Ultrasonic flow meter installation, minimum night flow analysis, IWA water balance and non-revenue water (NRW) calculation.
Pressure monitoring & management
24/7 pressure tracking with data loggers, anomaly reporting, pipe life and burst risk management.
GIS & street-level mapping
All fault and loss points are mapped with coordinates; the municipality receives an interactive map and a digital archive.
DMA, step & zero-pressure testing
Isolated zone setup and test methods narrow down which main the loss is concentrated in.
Training & consultancy
Training for municipal teams in acoustic listening, pressure management and digital infrastructure planning.
Working method
Four stages, a closed loop.
Preliminary assessment
The network map, meter data and the existing water balance are reviewed. Critical zones and a priority order are set.
Field measurements
Flow and pressure loggers are installed. Day/night acoustic listening is carried out and data is collected regularly.
Analysis & detection
Data is processed in a GIS environment. Leak points are located on the map and ranked by impact.
Reporting & repair follow-up
A fault report, water balance and NRW calculation are delivered. The loop closes with a post-repair check listen.
