Our Effort to reduce NRW
Cont inuously Replacing Old pipe
- Is it possible to replace 30% of Old pipes in total water network to reduce leak → Too much expensive
Set DMA (District Metering Area)
- It takes too much time to make DMA - Also well trained technician need to set DMA
Continuously leak detection by technician - Weak point of leak detection by technician Impossible to monitor leaks every day & everywhere
Result of currently leak detection NRW ratio 2010 : 10.8% (Korea) NRW ratio 2016 : 10.6% (Korea) Why the NRW is not increased? - Limit of a one-off detection - Lack of responsiveness for restoration leaks
Disadvantage of current method
Needs of Leak monitoring System
It takes more then 1 month to investigate same place
Area A detection
Area A redetection
● If leaks occurred very after detecting, technician will check the same place after a long time. So the leaking period lasts long sometimes it is more than 1 month
Using Leak monitoring system, reducing the leak period
Automatic Leak Monitoring without visiting
Current way Purpose of system
● Technician leak detection → Needs manpower ● Nighttime leak detection → Too difficult to find leak ﷯ ﷯ ● Using IoT tech without visiting ● Cloud data storing ● Analysis leak data with S/W ● Using Mobile & PC Ui ﷯
State of the art in Water leak detection field
System Introduction
Way to find leak with system
Leak(yesterday) > monitor(today) > fix(today) ● Beside of water meter, leak sensors are deployed ● Everyday, Sensors monitor and send leak info. to server ● With our S/W, analyze leak data & graphically display on the map → so we know where the leaking pipes are

Leak monitoring with wireless telecommunication (Leak pipe location, leak frequency, leak strength) Build Leak monitoring system to reduce water leaks
Leaks on service pipe(include leak inside of house )
● leaks occurred on pipes and connections ● Single sensor detects leak and sends a leak information to server ● On the map, single green mark turns into red
Leaks on main pipe
● leak sound from main pipe is spread through service pipes ● Sensors nearby main pipe detect leak and send info to server ● Bunch of green marks turn into red
