Quick Google stats: There are 13M households in California. Average household consumes 0.5-1.0 acre-feet of water per year. It costs $419 per acre-foot for desalination. California has a discretionary budget surplus of $49B. Thus: It would cost $2.7B-$5.4B per year to provide desalination-based water to all Californians. With the current budget surplus, we could provide 100% of California's living water needs for 10-…
I disagree that we should build desalination, even if we can "afford" it. There are agricultural users of water paying astronomically lower prices due to long standing water rights. It would almost certainly be cheaper to pay them to conserve (grow less of water-wasting crops, leave fields fallow, or upgrade to more efficient drip irrigation). The urban water use is around 20%, making them pay billions for this 20% m…

Pumping water from the California coast to Nevada is not a good idea. You’re basically describing a hydro plant, in reverse, carrying expensive water.
It also makes no sense because it would be cheaper and easier to just ween California off the Colorado river which already passes through Nevada and other states in the southwest. I think this is the easiest solution to the water problem there. You already effectively have a massive pipeline in the form of a river. Luckily, the state with coastal access has the highest water allocation for it.
I mean, it would probably work, right?

It is not politically possible to build desalination plants (or much of anything else really) in California. In just May of this year[1], a private company that had spent $100 million trying to get approval to build a $1.4 billion de-sal plant in the L.A. basin. It would have served about 400,000 homes but the permit was denied by regulators. Private money would build these plants if allowed. [1] https://www.reuters.…

By replacing one environmental problem with another: > The commission's staff experts said the facility would destroy marine life in about 100 billion gallons of seawater per year, and the company's ability to mitigate that damage with wildlife habitat restoration fell far short of state requirements.
> Environmentalists have long said desalination harms ocean life, costs too much money and energy, and the plant would soon be made obsolete by water recycling.
Well if that's true then awesome, let's get busy recycling water and "soon" we won't need to desalinate!
I actually wonder (yes, I'm not an expert) whether at some point drinking water will be valuable enough that you could profitably build a desalination plant in international waters and then deliver the water in tanks to the thirsty citizens who can pay for it. If you bottled at the source, maybe it wouldn't be more expensive than importing from France or Fiji?

I agree that LA is vastly more important than Sacramento but I doubt that was the reason for holding meetings there. When I am elected Governator, I will make my staff drive up Highway 49 and they will thank me for it.

You may need to check the orders of magnitude we are talking about here and then re-evaluate your statement. This is not about a few stretches of CA coastline. This is about all of the continental US. A few desal plants won't cut it.
> A few desal plants won't cut it. Then we build more than "a few".
- Residential: ~10%
- Industrial: ~20%
- Agriculture and farms: ~70%
Residential water is being rationed, but it won't make a dent unless we address that 70%, which to make it worse, loses half of that to evaporation and inadequate distribution networks. Solve the most glaring wasters and you don't need massive desalination anymore.

Parts of Nevada are below sea level so the total energy expenditure to move water should be "minimal". This would be after making aqueducts. My thinking is, if the Romans could move water over mountains without pipes, so too can the Americans.
Which parts of Nevada are below sea level? Lowest point IIRC is around 400ft.
Reno: 4500’
Vegas: 2000’
that’s a huge amount of potential energy to pump water from the sea

Not really much different than pumping Owen's valley water to LA...
A quick google search says Owen's valley is at 4k feet, while LA is at 300. I assume that reversing that would be incredibly expensive, considering the 570,000 acre-feet/year that flows is 1.5 trillion lbs of water. So, I think it depends on where it's being pumped from/to.
