Isn’t rainwater very clean? I mean, it’s distilled! Why buy a $5000 filtration machine? You just need a tank. A cistern. A personal dam.

It's probably cleaner in various open places, and certainly cleaner than the public water supply when it's falling directly from the sky into a cistern. However, I wouldn't trust any rainwater for my own drinking water in a metropolitan area because there's so much garbage in the air now. The toxins from vaping and cigarettes, for example. I want that filtered out.

Nestle launched a successful lobbying campaign to outlaw collecting rain water. Nestle is pure evil, and I wish I was being hyperbolic

Nothing new for them, look up what they did with baby formula back in the 1970s.

Rainwater is not very clean because of nucleation. Water vapor in the atmosphere will cluster around dust particles in the process of becoming rain, bringing down whatever pollutants/contaminants are up there.

So it can vary—if you’re near farmland there’s a strong chance your rainwater is non-palatable or even carcinogenic.

I mean, we’re just trying to flush toilets with it.

I understand that. I'm responding to you calling it "very clean" and suggesting it is so because it's "distilled."

Flushing and non-potable uses are great, but I never implied it wasn't suitable as greywater.

When it’s coming down, yes it is. However, if you collect it off the roof, for example, there is bird poop that can contaminate the supply. Depending upon how your cistern is built, it could contain mold spores.

Water recycling had been used for space travel, had it not?
