Trench out either side.
Get a 4ft length of scaffold pole or steel pipe and bash through to form a
sleeve for the water pipe.

I would like to get a 1/2in plastic pipe (for watering)
under the 3ft 6in wide granite-slab pathway in my front-garden.

Is there any clever way of doing this?
I don't want to lift the slabs,
which I assume have been there for 150 years.
