You can find an enhanced and approved proposal by the same author at Proposed features/drinking water.
|Proposal status:||Obsoleted (inactive)|
|Definition:||Indication whether water is drinkable/potable|
The general tag for a source of drinkable water is amenity=drinking_water. But in some cases you will want to subtag an existing OSM-object (like a fountain) with the info that the water is drinkable.
Usage in the database at 2014-02-09:
drinkable=yes/no is used 3240 times. Combinations: 82% amenity, 22% name, 13% man_made, 10% natural
|no||The water is not drinkable. It is obvious that the water is dirty or can be contaminated or flows through a circulating pump.
In some countries a sign "No drinking water" is not sufficient to tag no. It is possible that every source without official control gets this sign.
|yes||The water is drinkable.
If there are objective reasons that allow you to conclude that the water is pure, even though it is not checked. E.g. in alpine territory the source can be above any civilization. There should be no reason to doubt about the quality.
In some countries there can be a sign "No drinking water" because there is no official control. But one can assume that the water is pure because many people drink it every day.
There is no warranty for this tag. The circumstances can change every day. Everyone should use his common sense before drinking water from unknown sources.
|official||The water is checked and approved by public authorities. An alternative value may be potable.|
|mineral||The water is drinkable and has a special qualification, e.g. thermal water.|
- amenity=fountain - A fountain for cultural / decorational / recreational purposes.
- natural=spring - Water flowing out of the ground.
- man_made=water_well - A man made excavation in the ground to gain water from an aquifer.
- waterway=stream - A naturally-forming small waterway
