Looking one by one is already done on this chart: https://wiki.openstreetmap.org/wiki/File:Waterway_manmade_structures.png > not sure if waterway=pipe makes sense? From what I read, "culvert" is > describing that a waterway is flowing under something else, so it is not > generally applicable for waterways in tubes. > Both pipe and culvert aren't so good since it mix content and containers. Not all pressurised waterways are in pipe nor culvert. At least waterway=closed_space but it has less meaning than waterway=pressurised. According to this logic (split content from containers), waterway=canal should be replaced with waterway=river + canal=* and waterway=drain replaced by waterway=stream + canal=drain + intermittent=yes But it's out of scope of my proposal and it can't be done without massive re-tagging on existing features. Then I go on with waterway=canal for man made diverted water ways.
