I don't know how you call this in English (but probably it is called culvert), this is a closed tube for water which goes down on one side of the obstacle (e.g. road), the horizontally under it and up on the other side. As it is working without pumps it is required to be filled up with water at any time. Basically it work like a siphon. We call this "Düker" in German or "Duiker" in Dutch. http://dict.leo.org/?lp=ende&search=d%C3%BCker OK, got it (but the article is not mainly fitting): http://en.wikipedia.org/wiki/Inverted_siphon cheers, Martin _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
