Having two main tags... when it is  pipe and tagged man_made=pipeline 
the suggestion/proposal is to add an additional main tag waterway=*

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.
