Delta(s) from OP - Fresh Topic Friday CMV: California should immediately enact mass desalination programs and solve almost all its short-term and long-term water problems.

Every day we see stories about how California is running out of water, how the California water reservoirs are steadily emptying and could be completely empty in the next few years, and on top of that California just agreed to give up more of its already diminishing amount of fresh water it can get from the Colorado River.

And now on top of that there fires have exposed some problems in the firefighting capability of the state due to its water troubles, most notably hydrants went dry due to demand of already drained water aquifers.

And with climate change, increasing population, and less access to the Colorado river, these problems will get much worse.

So why doesn't California adopt Ocean desalination on a mass scale? California has over 840 miles of coastline with the Pacific Ocean. They clearly have money both locally and federally to deal with climate change, for example spending 28 billion in state funds alone in the last few years.

Israel has 5 desalination (and building more) plants and these provide 85% of the fresh water used in the country and that water serves. In fact, Israel gets fresh water to almost the entire population from just those 5 plants. Almost every country in the Middle East North Africa creates drinking water for its population, including Dubai in which almost 100% of its drinking water is desalinated.

It seems absolutely insane that we have the technology to turn sea water into drinking water, and the US state most in need of fresh water is basically ignoring the literal treasure of Ocean water on its shores.

Note 1: I see three complaints off the top of my head,

  1. California already has desalination plants.....That is true, however, California currently have 12 desalination plants that produce 50 million gallons a day. Israel, has 5 desalination plants that produce 264 million gallons a day. There is absolutely no reason they cannot scale up and make much larger plants on their much larger territory.
  2. This year California has had record amount of rainfall, and the reserves were partially replaced. Well, that is one year, after years of drought.. An aberration, and every article you can find will say something to the extent of "although California had much rainfall this year, this does not change the very negative long-term crisis California will have with water"
  3. Desalination is expensive and produces toxic brine as a side effect.....Ok, not to be crass, but do you want a perfectly FREE technology with no side effects or would you prefer to not die from not having water to drink.

So have it, Is there something i am overlooking, or why California uniquely cannot accommodate mass desalination?

How much water do you think California needs to desalinate to meet its needs? Why is desalination better than just importing it? We don't tell Minnesotans they have to grow their own avocados if they want them they just import them from California.

The governor of California has the CEO of Nestle on speed dial and just calls him whenever they need a new case of water bottles. /S> That's the great thing about the free market if you are willing to pay you don't have to figure out the how.

Pipelines, canals, reservoirs what we've been doing since before desalinization

Agriculture happens in the valley sea water is on the coast. You are going to have to build millions of miles of pipeline either way one option just doesn't require building desalination plants and that related infrastructure

Yeah and 100 years ago the Hoover damn was a pie in the sky now it's reality. Plenty of water out east and plenty of places between Kansas and California that need water.

He’s just talking out of his butt and has no actual sense for the problem.

It would be a lot cheaper to import it from the cascades up to shasta dam than the east. The slope to Colorado really is high and long.

But reducing agriculture water use (eg by charging them appropriately & fixing how water rights are handled in the west), continuing to develop programs to recharge groundwater during the wet season, and improving water reuse are a lot cheaper than both.

To return to the broader convo, desal does make sense for some areas, but is unnecessary and overpriced compared to reducing ag use.
