If you like carrying around a water bottle, then you probably like hydration stations, or other similar devices that allow you to fill up your bottle without getting your hand wet.
Maybe you thought they were restricted to new and renovated buildings on campus, but some oldies — like the Rock — have them too. See that little button in the upper-right corner of the water fountain? Indeed, that’s an old-school hydration station. There’s no motion sensor or anything fancy like that, but it does the job well.
As of my last observation, the ones on the third and fourth floors work. Sadly, the basement one does not. File a Facilities service request?
