Corrugated iron barrel drains usually work well enough, but not in this instance. For a time, it just looks like just a bit of water flowing over the road, before nature unleashed its full force on a man made structure. You may find watching the video like watching paint dry. I found it mesmerising. You should have your sound turned on to hear when the beast from the earth appears. In an even longer version, the drain can be seen lying many metres away amid the bush.
