Warin, I don't know if you followed the discussion and saw the proposal in the wiki. In short, it all started with the lack of good option to map a source of non-potable water, like a water tap. It evolved from there to the current state. The proposal from the last email reflects to ~90 % everything suggested as the discussion proceeded. I agree that water_purity sounds better than many other combinations though. So if you could suggest how to tag a tap with non-potable water, we can reconsider it. Cheers, Kotya
