I've often wondered what they do these days as people tell me you can see
the plastic pipes coming up for the services in new builds. Maybe they all
have some kind of local Earth spike or are they all joined together these
days and earthed at intervals down the road?
Interesting.

There was an ancient (1950s) steel pipe bringing mains water into my
house under the front room and then up in the cup'd under the stairs.
There there was a stop cock and it went into copper pipe and onto the
copper a large sleeved earth wire was connected with a tag on saying "Do
Not Remove".

The steel pipe was leaking so I have taken it all out and replaced with
blue plastic pipe. Was looking at the earth arrangement and wondering if
I need to earth the wiring in another way, into the ground or something,
or are we still earthed through the water in the plastic pipe out to the
outside world?

Water is NOT an adequate earth. An old electrical install with no earth is
not safe.
