for the pipeline there are tags, so we need them for waterways through cavities?
waterway=stream/river + tunnel=siphon for natural pressurized
waterways in a siphon. You could add pressurized=*, but I'd see this
implied by the term siphon
waterway=river tunnel=pipe pressurized=yes for man made pressurized
passages (maybe the pipe also already implies pressurized).
