Just wondering what others do for water filtration.  This is I believe an imporant aspect of travelling arou nd Aussie, one encounters all types of water.  I have fitted a filter in the van under the sink which filters everything coming in  the main tap, cold only.   I was also needing some info on obtaining water from rivers, dams etc, pumps and the like or the various methods used by others.  I would appreciate some comments from those who have been there.
