Pretty nigh impossible to do this, I'd say.
I wouldn't be prepared to touch it.

Wouldn't one of those metal/cable/wall stud detectors find them, BM? I'd have thought the piping would be be big enough to be sensed through the concrete. Failing that, contact a water diviner. Pipes are easy for them to find!!
