Would love for some clarity on what to tag these as. Currently it is tagged as

amenity=drinking_water
drinking_water=conditional;untreated

but clearly that does not adequately convey it is not safe to drink as everything treats it as "drinking water"

I've changed it from drinking_water to water_tap in https://www.openstreetmap.org/changeset/154575592 

I'm not sure if this is the best way to describe it, but it is certainly better than what it was before. Will leave this note open until someone else can verify it doesn't show up as drinking water anymore.
