These water bottle filling stations just started cropping up in the last few years. They are obviously useful, but also have a number of intelligent design decisions that make them better than they have to be. Filling up a water bottle at a normal water fountain is fairly impractical, so these solve a problem that isn’t a huge deal but is certainly an inconvenience. They are incredibly easy to use, with simple accommodations such as the outline of the water bottle with a sensor, clearly indicating how to use it. There is even a little screen counting the number of plastic water bottles saved through its use, an incentive to keep coming back, and to make more green choices.
