Comment on Half of Americans can’t install solar panels. Community solar is how they can plug into the sun.

They did not have good pressure with it either. Hence me asking what is really compared. Water distribution networks are also remarkably simple, so I am a bit curious about how he gets with the idea that people reproducing a thousand times what we have in a less efficient way is going to be more efficient overall.
Sorry, I don’t want to sound confrontational, I am just trying to get data on that.

Here’s a video showing Brad Lancaster’s permaculture house in Tucson, AZ:

I linked directly to a spot showing him getting good water pressure with only 2.5 feet (less than a meter) of head.
In other parts of the video he talks about filtration. You can watch the video yourself, it’s awesome. I hope it inspires you.
It sounds like the place you lived is not a great example of rainwater harvesting and greywater, like they didn’t really know what they were doing and cobbled together something mediocre. Do you think that water issues in Flint, Michigan are an indictment against the conventional water system? Or in India? I don’t blame you for having a bad personal experience with something and concluding that that thing is bad. That’s just how it goes. But take a step back and realize that the questions you have are solved problems. It’s just that most people are unaware and many are resistant to change.
The fact that the conventional water system is starting to run out of water in some desert areas, and that the problem is growing, is proof in itself that this system is unsustainable. So we need less pushback and more engaged interest.
Quoting Wikipedia from the Central Arizona Project article:
“The 456 billion gallons (1.4 million acre feet) of water is lifted by up to 2,900 feet by 14 pumps using 2.5 million MWh of electricity each year, making CAP the largest power user in Arizona.”
That is not simple at all.
“The canal loses approximately 16,000 acre-feet (5.2 billion gallons) of water each year to evaporation, a figure that will only increase as temperatures rise.”

To be honest, I am still trying to figure out what problem it solves. People should not live in deserts, that’s a given, but in most places, centralized healthy, pressurized, reliable water seem preferable to me. I get that some people want maximum autonomy for their home, and I respect that desire, but that’s a matter of personal preferences, not really a necessity of a sustainable world.
