There are a number of possible shades of potable: * It's not designated, but in an area where all faucet water is potable (e.g. major cities, fountains in rome). * It's designated potable. * It's designated as untested (e.g. "drink at your own risk") * It's designated non-potable by color or specific signage.
The tagging should definitely incorporate the physical color or sign associated with the tap. The tag encoding some invisible or informal knowledge I am not sure belongs. _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
