As I understand it, most North American cities 'recycle' via primary treatment of their sewage. Settling basins settle the suspended solids out of the water, and decant the water -- usually directly into the nearest water course. This stuff is still full of bugs. (The sludge is sometimes collected and sent to be spread on unwitting farmer's fields, but that's another issue. It renders the field poisonous for growing plants for human consumption for many years to come, aside from smelling like sh**.) With secondary treatment (could be: ozone injection, aeration... a whole series of technologies have developed) the pollutants are digested by bacteria in an accelerated way. Time and biological processes are the key. The same thing happens in an ordinary septic system. To actually drink the water, you'd have to chlorinate it or do something else to kill the bugs that remain. Now, don't flame me -- I'm quoting a sanitary engineer here and am not one myself. The point is, this process may take time, and may take biochemical assistance, but it is so do-able that millions around the world should not lack the ability to recycle water when they are in an area with limited water resources. Perhaps with Australia in the vanguard, the accessibility of this technology will increase.

You forget a very important point...most consumers of recycled water wouldn't know where to site their outhouse, if given the opportunity to do so...

But I am sure they have at least a bachelors degree in liberal arts...
