Hi Jono
I did this:
https://www.openstreetmap.org/node/5213660838#map=19/-28.07783/153.42664
for one stormwater drain nearby.
Would that work for your purposes?
Unfortunately it doesn't render in any way, so there's nothing showing on
the map to indicate that there's anything there, until you go into edit
mode :-(
Thanks
Graeme

I agree with https://www.openstreetmap.org/node/5213660838
location=underground
man_made=pipeline
substance=rainwater
I think it's okay to place this on a node if you don't know the
location the pipeline goes underground, even if the tags were meant
for ways.
Personally I would just add a way a few meters long to the end of the
stream and tag that, instead of a node.
But I'd omit the name unless it has one, "Stormwater easement" is more
a description than a name.

Thanks Graeme.

I don't quite understand the way extending to the north in your example
tagged just man_made=yes and surface=grass, is that the underground pipe
joining to the rest of the network?
Would that work for your purposes?
Regarding the node on the end, yes I think it should work. I always viewed
man_made=pipeline for legit big pressurised pipelines but I can't see any
harm using it for stormwater drains especially that some get really big.
man_made=pipeline
location=underground
substance=rainwater
The wiki page says man_made=pipeline shouldn't be applied to nodes but
there are already nearly 4000 so that can change, or if I have a decent
idea which way the underground pipes go (easy for the big ones) just map a
short way.
Thinking about how this would apply to other waterways I've mapped, I
currently map the streams or drains that pass under roads which rainwater
passes through like below, these are quite similar but with a completely
different tagging scheme.
waterway=drain or stream
tunnel=culvert
layer=-1
Do we use waterway=* where it is a naturally occurring stream but humans
earthfilled the location with a concrete culvert and put a road over the
top but that is still part of the earth's waterways of the creek system.
Can't be true because waterway=drain is for man made waterways.
This tagging also appears valid for a big stormwater drain where you can
walk into it:
waterway=drain
tunnel=flooded
location=underground
(https://wiki.openstreetmap.org/wiki/Tag:tunnel%3Dflooded)
Unfortunately it doesn't render in any way, so there's nothing showing on
the map to indicate that there's anything there, until you go into edit
mode :-(
I'm not too worried about rendering. In the past I've left a note on the
first node because these drain outlets usually can't be seen from aerial
imagery and many times the creek directly where it pours doesn't even look
like a creek from aerial imagery, so the intention was to capture the
information to ensure armchair mappers don't "fix" the creek.
As usual each time I post on the mailing list it opens a can of worms and I
learn too much about all the different possible tags :).
