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 François
