A dry hydrant is just a convenient drafting point for getting water in rural areas. Where I used to work as a firefighter we had designated water sources that we could use to supply tankers in the event of a fire. Many times it would be dangerous to get too close to the edge of a pond with the fire engine or would require more suction hose to reach to water than we would usually carry on the engine. In those areas we would install these dry hydrants. Hook up to them with a short piece of hard suction hose, pull a draft, and flow water. I would suggest marking designated water sources as that: water sources. If they have a dry hydrant then all the better and that should be mapped to make it easier to locate (especially at night). But dry hydrant or not, a pond, lake, canal, etc, that is suitable for fire water source operations should be mapped as such. Of course such ponds, lakes, canals, should be designated by the local authority. --Eric _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
