a water flow is there -> waterway=* (the same logic as for highway=*)
we already map "hardware" for road (surface) for building 
(building:material). did we need to delete those ?

1) a tunnel is not a pipeline !
2) not having a waterway=* is bad beaucase it break the continuity of 
the water network.
By analogy, when a trunk go into a tunnel,
we don't replace highway=trunk by tunnel=trunk
but we keep a continuity of highway=* network by having on tag
for "road network" and another tag for the tunnel it-self.
