Proposal

drinking_water=* indicates whether a feature provides drinking water, respectively whether water is drinkable for humans.

Rationale

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. There is already drinkable=yes/no in use, but it lacks a definition in the wiki.

There are also objects in the database, which can provide drinking water. To indicate this feature you can use the additional tag drinking_water=*. For example a public toilet may provide drinking water. The same applies to wells or mountain huts. As such this is one of the few OSM tags that can indicate the _lack_ of a feature you might otherwise expect (for example the rare highway rest area that does not supply drinking water, or the rare mountain hut where you must carry water to). It seems that this tag has also the usage of drinkable=*, see Current Situation.

It is proposed to use only one key drinking_water=* in the future. There is no need for doubletagging or ambiguous tags.

In the future drinkable=* will not be mentioned in the wiki. Instead there will be a redirection to drinking_water=*.

Current situation

Usage in the database at 2014-04-15, with combinations:

Key Total amenity man_made natural
drinking_water=* 3392 times 60% 12% 7%
drinkable=* 3384 times 81% 13% 11%

Both keys are mainly used with the same combinations.

How to map

drinking_water=* is used as additional tag for other elements.

Value Comment
no There exists no drinking water.

The water is not drinkable. It is obvious that the water is soiled or contaminated or flows through a circulating pump.

In some countries a label "No drinking water" is not sufficient to tag no. It is possible that every source without official control gets this label, although the water is drinkable. You can tag additional drinking_water:legal=no.

yes There exists drinking water.

The water is drinkable for humans. There must be objective reasons that allow you to conclude that the water is pure. E.g. in alpine territory the source can be above any civilization. One can assume that the water is pure when 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.

If the water is checked and approved by public authorities, you can tag additional drinking_water:legal=yes.

If there is a label "No drinking water" because there is no official control, you can tag additional drinking_water:legal=no.

conditional The water seems drinkable. You can drink it at your own risk.

If there is a label "No drinking water" because there is no official control, you can tag additional drinking_water:legal=no.

Additional tag

Other useful generic tag:

seasonal=* - Useful for features which appear or disappear with differing seasonal conditions.

Applies to

and others

The tag drinking_water=yes/no/conditional doesn't apply to amenity=drinking_water because this feature already implies drinking water.

Features/Pages affected

  • drinkable=* - Indication whether water is drinkable. Will be deprecated.

  • I approve this proposal I approve this proposal. (Just for nitpicking, I'd say that drinking_water=conditional could apply to amenity=drinking_water ) sletuffe (talk) 21:55, 17 April 2014 (UTC)
  • I approve this proposal I approve this proposal. it's good to see that someone took the time to clean up those 2 tags. Escada (talk) 03:52, 18 April 2014 (UTC)
  • I approve this proposal I approve this proposal. And we need a value (may be drinking_water=boiled) for the cases when you have to boil water from this source before drinking it. --Surly (talk) 04:00, 18 April 2014 (UTC)
IMHO "drinking_water" is used to tag an existing source, not to make proposals what to do with the water.--Rudolf (talk) 21:42, 25 April 2014 (UTC)
  • I approve this proposal I approve this proposal. Thanks for your good work on this tag. One small request: please remove the word fireplace in your example above about wilderness huts. There is an ongoing discussion about these heat sources inside shelters and I think the definition will change soon. AlaskaDave (talk) 05:18, 18 April 2014 (UTC)
The tag tourism=wilderness_hut was approved in 2012. I don't find any discussion on the talk-page. --Rudolf (talk) 21:42, 25 April 2014 (UTC)
  • I approve this proposal I approve this proposal. Very well researched and documented. Helps to reduce variety of keys. Hopefully we'll soon get rid of the old drinkable=* tags so evaluation is easier and uniform. Yggdrasil (talk) 07:19, 18 April 2014 (UTC)
  • I approve this proposal I approve this proposal. maybe the additional tag "drinking_water:legal=yes - The water is checked and approved by public authorities." could also be expressed with drinking_water=official? --Dieterdreist (talk) 15:33, 18 April 2014 (UTC)
That's right. The value "official" was removed due to a simple tagging and evaluation scheme.--Rudolf (talk) 21:42, 25 April 2014 (UTC)

  • I approve this proposal I approve this proposal. Brycenesbitt (talk) Yes, this matches the established convention. Should be clarified however: as with toilets we're talking about those accessible to the public. A shop that has employee only toilets does not get toilets=yes, nor does a shop that has water but not for the public get drinking_water=yes. There is also conventional use of drinking_water=seasonal (e.g. closed in winter or dry in summer). The seasonal= tag won't work except perhaps as drinking_water:seasonal=
IMHO seasonal=* works well. "drinking_water=seasonal" don't give any information about the season (summer or winter or something else).--Rudolf (talk) 21:42, 25 April 2014 (UTC)
