At most disused and not for public consumption. All the pipes are lead, and there's nothing here other than the little fenced off gate to the science museum. The nearest structure that could be public water is silted up, and looks like an old gutter (it's in a different location too, beyond the end of the Sheldonian). It has an unpopulated alcove, but isn't *in* it.
