It makes me wonder why the DNOs do not put in an earth rod (or tape or mat) every time that they make a junction. It would not cost much.
I believe that it has been WPD's policy for about 5 years now and they have a standard length of solid copper wire about 1.5 m long that looks as if it has been Thermit welded to a rod. It is made off in the joint and as Lyle's image shows, laid horizontally in all the joint jobs I've seen.
