Sorry for multiple emails... Anyway, the situation is this: 1) The water main diameter going along the street and (among other things) feed hydrants => fire_hydrant:diameter, according to the original meaning of this tag. It is generally acquired from signboards. 2) The water connecting pipe

It should be said that internal diameter physically change over time and operational status of pipes. Nominal diameter is theoretical value that is expressed in precise pressure and temperature conditions and true at anytime. It should be used on OSM since we prefer static data and +1 with Martin

Perhaps it's my fault, I just found DN = Diameter Nominal. The term Diameter Nominal refers to the internaldiameter of a pipe. Together with the nominal pressure rating and the materials class, all dimensions of a piping line, e. g. flange dimensions, are defined by indicating the nominal

In Belgium it is the inner diameter of the water main. Lowest value I've seen is 50, highest 400 or so. It's nicely explained on http://brandweerbrasschaat.be/site/content/hydranten (in Dutch) with pictures of the signs. The small ref number in the upper right corner is not always there. If you

Hi Viking, Good question, here is the situation in many French places. As Paul mentioned for British hydrants, it is now mandatory to put signs next to hydrants in French also. The roll out of such began in Paris : https://twitter.com/InfosReseaux/status/1061630374328131585 The displayed
