I thought this was kind of interesting, from California Public Radio station KPCC' s program about living in orbit. Astronauts preferring "pee water" to industrial "battery water."
4. Recycle EVERY drop
Astronauts learn to use and reuse lots of things, and water is no exception.
On board the space station there is "regenerative system" that captures moisture in the air and processes it into drinkable water.
"Everything from your breath to your sweat," Dyson Caldwell said.
They also recycle urine water by purifying it until it is drinkable.
"It's not bad," she admitted.
In fact, she remembered when her crew did a taste test between water from fuel cells brought by a space shuttles and the recycled water from the ISS.
"Folks preferred the space station pee water."

It doesn't take a lot of imagination to foresee a future where water which has supposedly been reconstituted from orbiting personalities goes on the market. It would be hard to prove that it wasn't.
"AUTHENTIC JOHN GLENN WATER!"
