I suspect pumping_station=sewage was the original way of tagging it but then
the pipeline people decided substance=sewage was better.  Taginfo has 883
uses  of pumping_station and only 165 pumping_station=sewage.  Taginfo has
1097 uses of substance=sewage, but a lot of those could be pipelines and
manholes, to which it also applies.  It can probably be deleted but I'll
until I'm happy about all the other changes before I do it,to give somebody
who lived through those changes a chance to say why it should remain.

Indeed.  But only required if the building is all there is to the pumping
station, to give an object to apply man_made=pumping_station to.  If
it's just one building amongst a collection of stuff, it's nice to add it
building=service but could be omitted if the aerial imagery isn't clear.

It could be real.  Not a problem if it's not.

Yeah, I'm not happy tagging a cabinet that way.  Single building I'm not so
sure of.  If it's not industrial landuse in an urban environment is it
in a rural one?

Which is why building=service is probably better in that case.  Anybody
know what the appropriate tag is for a cabinet (Australians, please don't
say "kiosk").

Because it's not obvious.  It's natural to assume that a wiki page which
tells you how to tag something tells you everything you need to know.
Otherwise people end up making up their own solutions, or keep asking
in the forum, or get frustrated because it doesn't work, or they end up
researching it as best they can then proposing a documentation change
on this mailing list.

I'd say what makes it landuse is more than one object and there's a fence
around those objects.  In borderline cases even a single building with a
fence can probably be mapped as landuse because there may be
underground objects within the fence that the mapper is unaware of.

I wonder when we're going to decide what to call large street cabinets. :)
