This is hilarious! But, the image is photoshopped. The pvc pipe has been edited to be under the faucet, when it actually leads to the white drain (which in this edit now leads no where.) The lead to the faucet is actually just between the upper middle of the fountain. You can see a second metal pipe above the pvc.
Still wouldn't drink from it though. People haven't washed their hands but are gonna get a drink AFTER peeing? No thank you.
