California Gov. Gavin Newsom has already issued an executive order calling on Californians to voluntarily cut their water use, and now the governor says mandatory restrictions could be coming soon.

Dont the enviros know how to harvest rain?
Everything is so green...A lot of this comes up from Baja /Gulf of California. In summer where I am it can go from 91 degrees to 77 inside of an hour. Nearly all summer it’s been this way. It’s like a south pacific Island. If I could bottle the smell during these rains I could sell it.
if California spent money on water infrastructure this conversation would not be happening. live in central valley part of California and the problem is infrastructure to retain mountain snow run off. California has diverted money that is meant to be spent on dams else where.
Please work on being less rude, less crude, and less uncivilized.
The D’s that stole the presidency are involved in the recall. He’s not going anywhere. You’re crazy if you think he is. 90% could vote him out and he’ll stay with the official tally of 45% for 55% against. This is the result of our inaction against the theft.
Agree...they push union construction jobs...so de-sal would fit that profile too.
A leader would make a major push for desalinization of only
we had a long Pacific Ocean coast line.

Israel is the world leader in desal tech.
They have water down to 52 cents per cubic meter as of 2020. That’s less than we pay for city water here in North Texas.
There is 264 gal to 1 meter cube we pay 4.5 for 1000 US gallon so 52c per M^3 = $1.96 per 1K gal. We have septic if we didn’t the city charges another 5.5 per 1K gal to take your waste via sewage system.
Desal is too expensive for agriculture except for very high value crops. There is 1233 cubic meters in an acre foot of water or $641 per acre feet of water. In the desert the evaporation transporation can reach 50+ inches of water per year per square foot. That’s over four feet of water that is lost and be irrigated to replace. That doesn’t include the water needed for the plants cellular respiration or growth which can be two more feet per year. Rice uses 6 or more feet per year there is no way water at $641 per foot can support rice or gay or alfalfa or pretty much any grain corn nope, the not even close rice would be 6*641=$3846 for just the water per acre of rice no way could the harvested grain cover that much water expense.
Study up on Israel.
Duck Duck go them or something.
They’ve really pushed for it, and if they can afford it,
we should be able to.
Thumbs up. Exactly right.
Raining again here in Phoenix.
Desal can be used for backup when needed—it would then be more expensive when used but it is a lot better than running out of water.
Less crime
A working economy
A stronger currency
A much smaller national debt
Less militant perverts of all kinds
As I pointed out desal at least the way Israelis do it cheaper than muni water is here in North Texas. $1.96 for desal vs $4.5 for the same 1000 gallons. We are too far from the Gulf to use desal directly but pipeline transport of water is not that expensive as long as it’s under 1000km and not up 2000+ meters of elevation. Neither would apply for North Texas we are 560km from the Gulf and only at 300 meters above MSL. The better choice would be to pay for desal water for Houston on the Gulf Coast and then take the equal amount out of the Trinity River system which today must flow down hill to Houston’s lake Livingston water source.
L.A. And San Diego should both be using Israeli tech directly on the Pacific. Phoenix, las Vegas, and Tucson should pay for the plants and the water for L.A. And San Diego then withhold an equal amount of water upstream in Lake mead for their own use in a one for one acre foot trade that keeps you from having to pump water up hill over the coastal mountains and then again over the Sierra Nevada mountains.
The economic will likely never work for the crops and flood irrigation, nor will it work in dry arid climate with ET values above 30 inches per year or more. There is a fundamental minimum in energy to Desal a cubic meter not even counting O&M for the equipment or capital depreciation plus interest. All of which add to the per unit cost.
“The theoretical absolute minimum amount of energy required by natural osmosis to desalinate average seawater is approximately 1 kilowatt-hour per cubic meter (kwh/m3) of water produced, or 3.8 kilowatt-hours per thousand gallons (kwh/kgal).”
The very best RO eff is double the minimum or 6.5 kWh per 1000 gal there’s 325800 gallons in an acrefoot. You will need 2100+ kWh per acre foot that’s an enormous amount of electricity now factor in to replace the 7 million plus acre feet that agriculture uses per year you get the idea of the power requirements. Put this way every acrefoot needs 2.1 megawatt hours of electricity and you would need 14+ million megawatt hours to replace Colorado river water not even touching the pumping power requirements. California shut down the only power source that has the steady 24/7/365 wattage to even come close to that amount of electricity the Diablo Canyon nuke plant. A 1350 MW reactor running flat out 100% for a year would make only 11,826,000 megawatt hours of electricity so you need two of them just to run RO process then you have to pump all that water uphill over the coastal mountains to the imperial valley and also the central valley farm lands. Deal is never going to replace what the sun does for free with evaporation on the oceans and precipitation over land the amounts of energy in that water that falls from the sky for free is mind boggling. California needs to.learn to live within its water means it’s that simple. The coastal areas can and.should supplement natural water cycle water with Desal but it will never replace Colorado River water on an agriculture scale.
Why you think that is so far fetched?
1960s slogan:
Save water.
Shower with a friend.
No one has ever accused this guy of being smart. Someone needs to cut off his crank before he reproduces again.
Some RO Units and a scattering of dams added along with proper water management would have set you up. But no.
I think it's a tossup between him and hidin' Biden.
