Thanks everyone. Apologies in advance for the long reply.
@Graeme I see you tagged the node with
man_made=drain_outlet+substance=rainwater. In your example it makes sense
to map the underground pipe because you know exactly where it is, but I'd
hate for these to start rendering in the future and bits of incomplete
pipes (a few metres long) start showing up drawing over streets.
The wiki for man_made=pipeline
<https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dpipeline> says it is
meant for "major" pipelines, which these aren't really apply:
By using pipeline are we abusing that tag? Dictionary.com's definition of
pipeline also indicates that a network of pipes isn't a pipeline. I too
don't view the reticulated water network of pipes a pipeline, however there
would generally be a pipeline going from a water treatment plant to a water
reservoir/storage tank; and in the same way the network of sewerage drains
aren't a pipeline, but you could have a pressurised or gravity pipeline to
move sewage to a treatment plant.
Mark's suggestion to use man_made=sewer didn't sound right to me because I
always view sewers as for wastewater which must go to a treatment plant
before entering waterways. Dictionary.com seems to agree, the values for
manhole=* <https://wiki.openstreetmap.org/wiki/Key:manhole> also agree, this
OSM tagging proposal also agrees
<https://wiki.openstreetmap.org/wiki/Proposed_features/Utility_Schema>,
however Wikipedia seems to indicate some people refer to stormwater drains
as sewers too, this might be a location thing because I found some
indication that some cities have a combined waste and rain water drain
(these obviously won't directly connect to a waterway).
substance=rainwater;sewage works though.
[...]
FWIW, I worked in the highway construction business for 14 years in the
US. In the industry terminology where I was, a "pipeline" carrying
wastewater to a treatment plant was termed a sanitary sewer, and a
pipeline carrying stormwater (rainwater) was called a storm sewer.
