DMA, step & zero-pressure testing
Isolated zone (DMA) setup, step testing and zero-pressure testing narrow down which main the loss is concentrated in; the measurement area is reduced.
Field services
We find, measure and prioritise water loss.
Each service can be taken on its own. The highest yield comes from running them all together within one programme and recording them on the platform.
01
Acoustic leak detection
Trunk-main crossings, patch areas, service connection points and critical points are listened to point by point at night, when network noise is lowest and the leak sound is most distinct.
The suspect point is narrowed down with a ground microphone and digital listening devices; with a correlator, the leak position is set to the metre between two contact points. The method is non-destructive; excavation is done only at the confirmed point.
- Equipment
- Digital ground microphone & listening rod
- Verification
- Correlator & noise logger
- Method
- Night + day, point-by-point survey
Night · survey with traffic safety
02
Flow measurement & NRW analysis
An ultrasonic flow meter is installed at reservoir outlets and critical network points; flow is logged for 24 hours.
A minimum night flow analysis is used to calculate the physical and apparent loss shares. In line with the IWA water balance methodology, the non-revenue water (NRW) rate, the loss volume and its financial value are reported.
- Measurement
- Portable ultrasonic flow meter
- Average NRW across Türkiye
- 30–40%
- Physical-loss share of minimum night flow
- ~70%
03
Pressure monitoring & management
24/7 pressure tracking is carried out with data loggers placed at critical points. High- and low-pressure anomalies are reported.
Evening out the pressure lowers the leak flow and the risk of new bursts and extends pipe life. Pressure problems are often related to the distance from the pump; for a correct diagnosis the measurement points are chosen systematically.
- Equipment
- Pressure data logger 1–30 bar

Other services
The work that completes the programme.
GIS & street-level mapping
All fault and loss points are mapped with coordinates, sound level and a photo. The municipality receives an interactive map and a permanent digital archive.
Training & consultancy
Training for municipal teams in acoustic listening, pressure management, water balance and digital infrastructure planning; building in-house capacity.
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.
