Anyway, some extra detail I forgot to mention - the pipe is in the back garden, at the far end well away from the house. All the terrace's gardens end in a slope down to a lane with garages, the pipe is at the top of the slope.

Hi There, its more likely to be a water pipe ? try making a 'sounding horn' from a length of metal pipe and hold one end against it and the other against your ear, you might hear water running it its in use but of course this is not a guarantee. You might like to try listening at busy 'water use' times ? 8-15 am and 5-30pm ?
just an idea ! Lannerman.
