Water leak location in industrial area in Voskresensk

Location equipment to be used

• Cable and pipe locator "Success AG-319N"
• Acoustic water leak detector "Success AT-407N"

Solution

There is a manhole near pump station. Pipe is accessible from the manhole. We connected signal transmitter of cable and pipe locator "Success AG-319N" to the pipe in manhole and decided to trace it as layout schemes are missing.

Manhole is flooded, that is why it should be drained before connecting the transmitter to the pipe.

During the location, we used contact connection of the transmitter to the pipe. Pipes are very rusty. In order to connect transmitter to the pipe we cleared the rust and used supplied magnet. Connected one crocodile clamp to magnet. Second clamp we connected to grounding rod at maximum distance from the pipe.

Initially we set AG-120 transmitter power to 20W, 512Hz frequency, pulse mode, but transmitter could match with these settings. 20W power can be too high for such pipe that is why we decided to change settings. We set 10W , 512Hz, and switched the signal to continuous instead of pulse. The transmitter matched with the load and we could start location of the pipeline.

Usually, metal objects affect the location process. But we have managed to trace the utility without any trouble.

Client didn't know where pipe was going, that is why he marked the position of the pipe following the operator with locator.

Following the route we reached the pond. Receiver indicates that pipe is going below the pond.

We have walked around the pond and detected the signal from transmitter on the other side. It took us to next manhole.

Distance between manholes was 260 meters.

All route was inspected with acoustic water leak detector "Success AT-407".

Pinpointing inspection confirmed the point with maximum noise level. It can be a leakage spot.

Result

TECHNO-AC equipment perfectly located the leakage in real field conditions. Location of leakages saves time and money on wasted water and pipeline servicing.

It is strongly recommended to locate the pipe itself before water leakage location. Location will help to trace the pipe, evaluate it route, locate manholes, valves etc.
