All water is recycled. No-one is making virginal water. There's no such thing as 'fresh' water. It's all been round and round and round, through countless millions of kidneys. The only issue is, has it been cleaned up before we drink it?

Actually, water is being made and destroyed all the time. Our cars make water in the chemical reaction that takes place in the burn inside the internal combustion motor.

But I get your point.
We can clean water very well but not as well as nature. Here in Melbourne, there is no reason why we should be drinking recycled water. Using it for irrigation, gardens and flushing the toilet, yes, but not for drinking or food prep.
In Melbourne, new suburbs should have dual reticulation systems. Recycled and drinking.

But where does that water from the burn actually come from? Is it really new water or was it already in the atmosphere, as part of the Earth's water cycle? That's changing the nature of the water, but not actually creating it from nothing. It already existed in a different form. Is that right?

Creating Water from Thin Air - Why can't we manufacture water? | HowStuffWorks

Interesting article. It deals with collecting existing H2O, Di-Hydrogen Oxide (aka water). There is no mention of changing the nature of water. Can this be done?
They do describe some of the different states of water which are gas, vapour, liquid and solid.
New water can be, and is indeed, manufactured. I have a water manufacturing machine.
Here is the relevant equation of the water manufacturing machine. There are other chemical making processes involved.

Interestingly, at one atmosphere at a temperature where octane and water are liquid, this machine produces more water by volume than volume of octane used. Or so I am told.

Oh, and water can be destroyed. I have a device for doing that. Want the equation for that too?

Nothing great about it at all.

My brother flies a lot and remarked 10 years ago that coming into Melbourne is unusual because you're flying over houses for quite a while before the pilot lowers the wheels.

I re-cycle as much of the water in tea, beer and wine as I can, so it can be incorporated into more of the same.

A mate of mine (with a PHD in organic chemistry) told me years ago that every glass of water (or whatever) one drinks would contain at least one molecule of water that would have been with the dose of hemlock that Socrates drank, back in the day.

Water molecules are very stable.

I dont see any shortage of water on the planet. Only a limit to the collection and storage. Want more? Collect more.
