We already have man_made=pipeline
It is only the nutshell, how the conduit is actually built, not what's
going inside. Substance=water is recommended and useful but not enough to
qualify the flow.
A pipeline may be opposed to tunnel. In the current situation it's
certainly a pipeline and not a tunnel.

According to https://wiki.openstreetmap.org/wiki/Key:waterway#Values
waterway=drain is suitable for discharge of superfluous water, which rain
water actually is.
As waterway=canal, a drain is always free flowing in open air. For
pressurised water conduit, use waterway=pressurised (if intake is always
below water level in operation, in the catch basin)
Then usage=sewer or usage=discharge would be ok.

All the best
