Is amenity suited? man_made=fire hydrant would be better to my opinion, because an hydrant is not intended to be used by everybody. And it it not used in a convenient/pleasant way. ---user:HB9DTX

Agree, but it comes in same category as amenity=prison and amenity=architect_office. I do not find a prison pleasant (prefer not to have one close to my house or near my hotel), and never used an architect_office in a pleasant way... --Skippern 01:00, 6 January 2010 (UTC)

I think the standard tag should be emergency=fire_hydrant. My reasoning is that an amenity is a general use or large population use location, where a hydrant is only legally used by emergency services. A prison still fits into amenity for the same reason, as the general population (criminal) is housed in such a location, but the facility isn't exclusively used by inmates - for example visitors. A fire hydrant is only used by emergency services and occasionally by some member of the government aka water authority. I also think the 'man_made' feature is silly, there is no need to define that a fireplug is man made because the structure is not created naturally. Man_made makes sense for things like ponds which also can be natural to differentiate the two types. Rjhawkin 03:14, 31 July 2011 (BST)

With your argument about prisons, one could also include apartment buildings, a lot of people are housed in them. --Skippern 03:48, 6 September 2011 (BST)
That is a spurious argument as people living in an apartment house are doing so under a limited amount of choice while a prison is less about living location.Rjhawkin 18:36, 20 January 2013 (UTC)

Wrench used to open

In the place where I live, there are some hydrants that are secured, that is you have to open it using a square or pentagonal wrench. I think that this distinction could be useful (which wrench has to be used, if any...) --SteveVG 17:22, 20 July 2012 (BST)

This is not needed in my opinion. The people who have legitimate needs to access a hydrant know what types of wrenches are needed. Knowing where a hydrant is on the other hand is important in the sense that it allows generation of fire protection area maps and can affect the response time during a fire or related emergency. It could even affect how long it would take to fill a private pool since they are used for that purpose as well. The problem with unauthorized opening of fire plugs is that because the volume of water is so great it can decrease the water pressure available in that area for other municipal users and potentially have it so that there isn't enough pressure at another location making a fire harder to fight.Rjhawkin 18:36, 20 January 2013 (UTC)
To the point of those with a legitimate need knowing, actually they may not know. Firefighters on Mutual Aid calls may not know what the correct wrench is, in particular in cases where they are providing support in places that are significant distances from their home district (think Upstate NY firefighters helping out in NYC after various issues in the recent past.) Nfgusedautoparts (talk) 19:37, 27 February 2014 (UTC)
I favor adding this tag. there are potential applications of OSM in emergency response where documenting this could be quite useful. Nfgusedautoparts (talk) 17:41, 27 February 2014 (UTC)

Adjustments to fire_hydrant:type, addition of fire_hydrant:water_source

there is an easily correctable issue with the current configuration of fire_hydrant:type=*; the problem is that it inappropriately conflates true types (pillar, underground, etc.) with a water source (pond). i recommend that pond be deprecated as a type, and that fire_hydrant:water_source=pond,stream,main be added. additionally, i'd like to see two more specific types added, dry_barrel and wet_barrel. these are proper subtypes of fire_hydrant:type=pillar. Nfgusedautoparts (talk) 17:47, 27 February 2014 (UTC)

Potable water

I think it is good to tag if the water is potable (drinkable) or not; this can at times be useful. See for example color codes here.

I am currently using fire_hydrant:potable=yes;no;unknown; unknown would be the default value if none is specified.

Service Water Hydrant for Livestock Watering

Any sugestion how to tag these kind of "hydrants"?

They are used to fill mobile watering tank trailers (which are placed on cattle pastures).

amenity=watering_place, amenity=drinking_water or emergency=fire_hydrant doesn't seem to fit here. --Bmog (talk) 19:20, 12 October 2014 (UTC)

The function is similar to railway=water_crane ?
But the meaning is amenity=water_point.
We could add water_point=water_crane ?

New tags

Hungarian mapping community works together with water works and firemen. We suggest new keys for hydrants:

Kolesár (talk) 12:47, 19 March 2015 (UTC)

fire_hydrant:signage=marker
fire_hydrant:signage=plate
fire_hydrant:colour=* use colour=*
fire_hydrant:signage=missing : Why not something more general like fire_hydrant:issue=missing_signage ?

Clarification of diameter

Please make it more clear/plain that "diameter" refers to the source feed of the hydrant, and not the hydrant pipe (pillar) itself. The present phrasing of the second sentence is also ambigous: while the signboard has the diameter of the feed (like "H300"), the cast iron pillar has the diameter of its connection (like "DN80") - so should I read the pillar or the sign? ITinerisKft (talk) 14:52, 17 January 2019 (UTC)

You are right. Afer a brief consultation on tagging mailing list, we have verified that fire_hydrant:diameter was created for the diameter of the water main going along the street and in many countries you can read this diameter on the signboard above the hydrant.
When I rewrote fire hydrant page, I did an error: I confused the diameter of the water main going along the street with the diameter of the flanged connection between the water main and the hydrant, because here in Italy the diameter of the water main is not reported anywhere (nor on signboard nor on hydrant).
Now I will fix fire_hydrant:diameter legend, removing references to the flanged connection. Contestually I will remove fire_hydrant:diameter tags that I added, because they report wrong values. --Viking81 (talk) 18:05, 31 January 2019 (UTC)
In france, this is the internal diameter of the largest connector. The minimum size is DN80 (mean normalised diameter of 80 mm), but usually this is DN100.
There is no signboard, but the color of the top of the hydrant (or the reflector) give the diameter: White DN100, Yellow DN150.

Pond deprecation

"fire_hydrant:type=pond is deprecated because it has been replaced by water_source=pond."

Then how features like https://commons.wikimedia.org/wiki/File:Dry_hydrant.jpg are supposed to be tagged?

Mateusz Konieczny (talk) 04:49, 26 February 2022 (UTC)

Based on an overpass turbo query around Central and Eastern Europe emergency=fire_hydrant in combination with water_source=pond and fire_hidrant:type=pipe. But some mapillary or other geotagged photos would indeed help this question. Beringer.Zsolt (talk) 07:38, 26 February 2022 (UTC)
The pond feature itself, and direct attachment to the pond, are different data from the water source info of an arbitrary hydrant (could be far away). They may be related spatially by drawing the natural=water + water=pond + emergency=fire_water_pond (although I believe "firewater" should be one compound word) next to it, and connecting with man_made=pipeline (with an inlet=*). Question remains for showing direct attachment explicitly, and purpose of emergency=suction_point (can there be an area, or must type=site be used?) .
fire_hydrant:pressure=suction is mentioned in both Tag:emergency=fire_hydrant#Basic_tags and Tag:emergency=suction_point#See_Also.
Not sure about your "dry" here. I assume any hydrant can be dry or wet, be it pillar or pipe. That's why pillar:type=* and fire_hydrant:type=* are flawed. (What does the "barrel" in pillar:type=*_barrel mean anyway?) We also have emergency=dry_riser_inlet separately, but 0 instance of emergency=dry_riser, emergency=wet_riser, and emergency=wet_riser_inlet.
--- Kovposch (talk) 11:02, 26 February 2022 (UTC)
Last time I had something like that I used fire_hydrant:pressure=suction plus fire_hydrant:type=pipe. Jengelh (talk) 13:21, 26 February 2022 (UTC)

Clarification for fire_hydrant:position?

Hi there, I have recently been using the StreetComplete app in order to fill out information regarding fire hydrants, mostly where they're positioned.

I have been running into an issue where I have a hard time figuring out how to tag fire hydrants that are placed in patches of rocks, much like the patches that are sometimes seen in front yards of houses for decorative value. I'm still fairly new to contributing to OSM, but have found three or four cases where I was unable to make a selection based off the four current values due to this.

I have also run into a singular instance where I found a fire hydrant that was positioned in artifical turf. While that has only occured once, I was still curious to know as to whether that would fall under the green value, i.e., if artificial turf is still recognized by OSM as being "grass".

Thanks for any clarification and help in advance. Binzy Boi (talk) 09:45, 5 May 2022 (UTC)

There can certainly be problems with fire_hydrant:position=*. It is mixing location with surfacing. I assume the intention is to show any possible concealment.
There is 1 fire_hydrant:position=stones node 8714430627 and 2 fire_hydrant:position=gravel instances you could follow. Ideally your rocks and the *=green can be separated out. Something surrounded by rocks could be covered in grass, sand, gravel, or something else. The rocks may be moved at times. They aren't really a "position".
Anything that resembles vegetation should count as fire_hydrant:position=green. Grass is only one example.
Problem with fire_hydrant:position=parking_lot is a carpark consist of many parts, aside from the example photo File:Fire-fighting-facility node-4279866277.jpg actually showing a street-side parking node 4279866277. It appears it meant any parking spot. There may also be some confusion with fire_hydrant:position=lane when there is parking:lane=*. --- Kovposch (talk) 03:04, 6 May 2022 (UTC)
In such confusing cases you can leave note with a photo. You can ask also on some of Contact channels or Tagging mailing list - new https://community.openstreetmap.org/ may be easiest to access, you can login with OSM account @Binzy Boi: Mateusz Konieczny (talk) 08:04, 10 June 2022 (UTC)
Also note the discussion at StreetComplete issue #4138. --mnalis (talk) 13:12, 21 June 2022 (UTC)

I am missing a value for fire hydrants in a pedestrian area, because it's neither a lane nor a sidewalk (and not green in many cases) and it's quite common. I've been using the fire_hydrant:position=pedestrian_area value for a while. Could this perhaps be added or is it a problem? I would prefer that instead of defining, that sidewalk should also be used for a pedestrian area (or other kinds of footways or even cycleways which are not sidewalks) because it's just not the same (nor does the wiki text mention it). And it would also be counterintuitive to me and contradict the definition of sidewalk=*. Unfortunately, there weren't any good extensions for new values of fire_hydrant:position=* in the last proposal. --Goodidea (talk) 00:21, 23 November 2022 (UTC)

parking lot

Hydrant in a grass within parking, but outside area used for parking vehicles would be fire_hydrant:position=green - right? Mateusz Konieczny (talk) 13:57, 8 March 2023 (UTC)

Yes. fire_hydrant:position=* isn't very good. --- Kovposch (talk) 04:34, 9 March 2023 (UTC)
I've never liked fire_hydrant:position=* myself since "green" isn't a position so much as the surrounding environment that the fire hydrant is placed in. Most of the times I've used it the green was more to do with the area around the fire hydrant being over grown then anything else to. So, it's not a very tag. --Adamant1 (talk) 05:22, 11 March 2023 (UTC)

Coupling types and diameters, how to tag multiples?

I'm interested in mapping several hydrants in my local area, but want to get off on the right foot. In my area, and many parts of the US, a typical fire hydrant has three couplings...one large "pumper" port and two smaller "hose" ports. And on many modern hydrants, these couplings are of different types as well...often 5" Storz on the pumper outlet and 2.5" national hose (NH) threads on the hose outlets.

After a brief discussion in the #tagging channel on OSM Slack, I have been leaning toward couplings:type=storz;NH;NH and couplings:diameters=5";2.5";2.5" to encode this information. But, it feels a little weird that the "type" in the tag key is singular and holds a list.

To add to the confusion, while 5" Storz is becoming popular, there are still _plenty_ of hydrants around where the pumper outlet is NH, but a larger size than the hose outlets...often 4.5" NH. For that, I suppose couplings:diameters=4.5";2.5";2.5" makes sense and either couplings:type=NH;NH;NH or just couplings:type=NH?

Foaming agent

At some places we have hydrants that serve foaming substance diluted in the water, like at oil refineries or airports. Any ideas how to tag them instead of the usual water_source=main? ITineris (talk) 10:41, 5 April 2024 (UTC)
