Guidance of various investigation construction methods

Leakage of water investigation of service pipe
Leakage of water sound is directly detected at the water meter and a valve using a listening stick.

                
Leakage of water investigation of distribution pipe

The leakage of water sound from buried water pipe is detected on the road surface using water leak detector.



                

Correlation investigation method
A leakage of water position is judged using the difference of the speed from which the sound of leakage of water is transmitted.

      

       
            
Pinpointing of a leakage of water part method
In Japan, it is necessary to identify the leakage location, to check the status of the ground with a hole.

                 
Continuous monitoring investigation method
It is a construction method which always supervises leakage of water using Continuous monitoring equipment.
It supplements with the sound of leakage of water correctly, and if the equipment which always continues supervising leakage of water is installed in two or more places, it will become possible to supervise the wide range effectively.
                
Air pressure feed construction method
It is a construction method which sends air to a water pipe and makes leakage-of-water sound amplify. It uses, when there is little quantity of leakage of water, or when the sound of leakage of water is small.
Gas trace detection method
In order to discover leakage of water, it is a construction method which puts in helium gas or non-inflammability hydrogen gas in a water pipe, and detects gas on the road surface.
It is possible to discover the leakage of water in which it is difficult to discover to eyes or sound.
