If this is dual tagged with man_made=pipeline then it would be
better as a property tag as Martin suggests.
What do you mean with "dual tagged" ?
Having two main tags... when it is pipe and tagged man_made=pipeline
the suggestion/proposal is to add an additional main tag waterway=*
Getting tired of searching for the proposal .. here is a link ..
https://wiki.openstreetmap.org/wiki/Proposed_features/Hydropower_water_supplies
In this way the pipeline tag can also use the property
'pressurised' .. and that property could be expanded to include
numbers.
The tag pressure=* is here for that, the value can be given in bar
https://wiki.openstreetmap.org/wiki/Key:pressure
This is pretty easy to get this value for a penstock : pressure =
(elev up - elev down) / 10 in bar
Are all of these these proposed waterway=pressurised in pipes?
You can gather I find the proposal confusing...
Talk of canals and .. they are not part of this?
If these are all pipes .. then waterway=pipe would be a good
description, use pressure=* as a tag for the pressure.
