Underground Piping - Leak Detection Services

[Esbirinai]

I have several leakages on a long underground water piping (10") system.
The piping is burried 3 meters under and We are desperate to find all the leaks. To make it more dificult we do not know the exact location of the underground pipes.
Is there any European or US company that could do this kind of job? If not, what equipment is available to find the pipes and detect undergroud leaks?

Thaks in advance,

DL
