tracking (toilet) water

Have you ever thought of where the water goes after you take care of your business in the bathroom? You don't think that the water comes from nowhere and disappears as you flush, do you? Here is a pretty map shows where the dirty water flows into. I haven't personally tried yet since I live in outside their cool map range. Too bad, it is only available in UK, Ireland, South Africa, and Poland (what a random choice) - would be awesome to see/track in every urban area. This Flush Tracker will be not only a fun map for a map nerd like me, but also a good educational tool for young and old. By tracking the water, you will find some relations between your (self-centered) life and the natural environment (I think).
