Reply to comment by thintoast in U.S. Streams Are Drying Up. Data showed that in the South and West, streamflow droughts got longer between 1951 and 2020, regardless of threshold. Worse yet, droughts in these regions are becoming more intense by Wagamaga
Population of Ireland 4.6 million
Population of the United States 326 million
Population of China 1.39 Billion
You see how rain barrels aren't going to scale?

This is a silly comment. You would need to do an analysis that involves population, population density, rainfall, rainfall density and frequency, etc. in order to say whether or not that kind of system would scale. Not just looking at population.

And determine where unlimited rain water harvesting is still legal… Colorado has already regulated this and I’m sure they aren’t alone

Colorado legalized collecting years ago...right after the longest hardest rains came to a sudden and permenant end. I collected ridiculous amounts of water, then found out I wasn't allowed to, dumped it and then they changed the damn law.

They codified a limited amount of rainwater collection. Colorado did nothing to legalize it, it’s been legal since the dawn of time

How many rain barrels you need to wash 100,000 people's hands?
10,000 people?
1000 people?
100 people?
1.28 gallons per toilet that's 69.5 Billion gallons required to flush Chinese toilets if they only flush once day. 50 gallons per barrel, you need 1.39 Billion barrels filled every single day.

This pedantic argument totally misses the point. It isn't that rain water is the answer for the whole world. It is that treated potable water shouldn't be used for toilets. In some places rain water may work. In other places lightly filtered gray water (sink & laundry) might do the trick.

Why would you only have a fifty gallon barrel?
Here in Australia a small water tank is about 250 gallons. It’s not uncommon to find tanks twenty or even fifty times that size.
I know plenty of people who run their entire house with rainwater.

The law says 110 gallons max. There's a deal to get water from the Colorado River signed by five states, taking water on residential properties prevents water from running off into the river.
Something like 70% of Australia is uninhabitable.

A large area of Australia is uninhabitable, which is why we use big-arse tanks to catch the rain.
In most new dwellings in some states (even—especially—in cities) it’s mandatory to have rainwater tanks installed.
