In this corner of world using water pipes for earth-bonding has been
illegal for last 50 yrs.
There are lots of good reasons of safety reliability testability etc.
Metal pipes get replaced with sections of plastic, connect to high
leakage immersion water heating elements, connect to gas pipes &
external piping. Metal pipes are meant to be bonded to earth system.
Here metal water pipes & metal sinks-tubs-benches shower trays should be
bonded to the earth bonding electrode system although most of them
aren't..

I believe high lightening strike areas (like parts of US) have more
strict rules, for instance bonding antenna coaxial cables etc.
