How to map

Tag a Node at the appropriate location with emergency=fire_hydrant. The following additional tags may be appropriate:

Proposed attributes:

  • fire_hydrant:flow_capacity=#/in cubic meter or GPM (optional), the following additional tag are for important for Firemen because the pressure is done by the fire truck's pump. In France, a normalized Fire_Hydrant need to supplied 120 m^3 during two hours. In the US, this specification is in Gallons Per Minute (GPM)
  • fire_hydrant:class=AA/A/B/C. {optional} In the US, classification per the American Water Works Association (AWWA).
  • fire_hydrant:water_source=main/pond/stream. {optional} the water source for the hydrant.
  • in_service=yes/no. {optional} Indicates whether a hydrant is in service or not. Absence of tag connotes unknown.
  • fire_hydrant:location=* (optional, if better or detailed description of the location is necessary)

The tool OsmHydrant eases the process of adding and editing hydrants to OpenStreetMap.
