If we want to be pedantic, it's how it works IRL too. All the water on Earth has been here for an eternity, with all its piss, feces, cadavers and whatnot inside of it. Completely fine if properly reprocessed.

If you want to be really pedantic, water is created and destroyed all the time, it's just a relatively stable process. Water is destroyed in the upper atmosphere and by lightning, and is created in volcanic eruptions and combustion. (Among many other ways)

Speaking of pedantic, matter is never actually truly destroyed.

Water can definitely be destroyed.

To be more pedantic, matter can be "destroyed" by converting it to energy. The sun does this at a rate of 4 million tonnes (4 teragrams) per second.
