Excellent, I am looking forward to seeing the corrected file.

The cases I saw were not inside multipolygon buildings

If they are truly on top of the building in reality, then they should be on
top of the buildings on the map, however, the ones I saw were not on top of
the buildings in reality (based upon the photos that the data linked to)

This is something that should be addressed during the actual import, and
your instructions should specify that this will happen.  Since you haven't
provided us with your proposed instructions/procedures I don't know what
you are planning, but with data like this you should not simply upload.
You should break it into manageable chunks, review against existing data,
including buildings, and make adjustments as necessary, and only then
upload to the OSM server.

If there is no reasonable way to get water out of a tank directly,
especially if you have mapped the associated tap separately, then the tank
should not be tagged as amenity=water_point.  According to the wiki[1]
amenity=water_point is 'for places where you can get larger amounts of
"drinking water"....' The tank can be tagged as man_made=water_tower or
man_made=storage_tank + content=water.  This will depict the "distribution
network", but will tag each component of that network as to its actual form
and function.  Along these same lines, wells should be tagged as
man_made=water_well along with associated tags.  The wiki[2] has an example
of a well that looks very much like many of those in your data (second
example).
