Can someone tell me what happens to the water in the water system....

[IxxTreasuredSoulxxI]

After it is flushed or washed down the drain or shower drain? Where does it go and how is it 'cleaned' so it can be used again? How is all our poo filtered out?

Pardon me for being curious :doh: I just saw a commercial and it got me thinkin! :wild: :cheeky: Yes i'm serious! lol So take me seriously
