Sorry, my mistake, i didn't think of tanks. The wastewater plants i've mapped so far have concrete lined depressions like those on these images: https://commons.wikimedia.org/wiki/File:Flug_Leer_nach_Emden_2010_11.JPG https://commons.wikimedia.org/wiki/File:Kläranlage_Heidelberg_Grenzhof.JPG https://commons.wikimedia.org/wiki/File:090913-EpurationOupeye_0020.jpeg https://commons.wikimedia.org/wiki/File:Sedimentation_tank.jpg I think it's okay to call them basins, isn't it? > Secondly, if you're going to apply landuse to a man-mad object rather than to > an area of ground > that holds a collection of man-made objects then instead of building=house we > should have > landuse=house. We don't do things that way. You're right, basins aren't land uses. What about man_made=basin and man_made=tank then? (I know that there is man_made=storage_tank, but these tanks are for treating waste water, not for storing them.) These tags could also be used for basins and tanks that serve other purposes, for example slurry basins or tanks.
