In the Bay Area we have several square miles of Salt ponds to produce........SALT. So instead of evaporating water into the atmosphere so you can get salt, why not use desalination plants to give you....water AND Salt.....Makes sense (So that is the reason they won't do it)

Then again, I have been told that Man could never pull this kind of engineering off......Too expensive and complicated.....It would be like the Romans building aqueducts back 2000 years ago.....That would be crazy....right? |

Did you know that there are no large diameter pipelines carrying crude oil, diesel and gasoline from the Gulf Coast or West Texas over the Rocky Mountains to the Western states?
Ever ask yourself why?
Now, apply that answer to a product (water) that weighs considerably more than oil diesel, or gasoline.[This message has been edited by maryjane (edited 10-09-2021).]

Desal water in Calif costs a average family of 5 about $2,200/year if all that family's water came from the desal plant.
Desal plants are expensive to build, expensive to maintain, and expensive to operate, with electric power being the biggest cost, with RO membrane replacemnt being 2nd largest cost.
From a nearly 60 year old song:
| quote | Gather 'round me people
There's a story I would tell
'Bout a brave young Indian
You should remember well
From the land of the Pima Indian
A proud and noble band
Who farmed the Phoenix Valley
In Arizona land
Down the ditches a thousand years
The waters grew Ira's peoples' crops
'Til the white man stole their water rights
And the sparkling water stopped
Now, Ira's folks were hungry
And their land grew crops of weeds
When war came, Ira volunteered
And forgot the white man's greed |

It was from that song, as sung by Johnny Cash, that I first heard of Ira Hayes.

Nestle doesnt have any problems bottling water to sell out of those Western states.

You're correct but in an emergency situation like this, they should be built and on standby until the next rainy season.....if we ever get a TRUE rainy season. Once reservoirs fill up from rainwater and we are out of the drought, the plants shut down until the next emergency.

Back in 1908 they built the Los Angeles Aqueduct from the eastern side of the Sierra Nevada mountains over them to the LA basin.....They were able to get the water up and over via.......Gravity; The water going up the hill was pulled by the weight of the water dropping down the far side. Brilliant!
Side note; A flood washed out part of the aqueduct where (down low) it crossed a wash.....The suction in that section collapsed the iron tubing for miles. It was going to cost MILLIONS to go and replace all of that iron tubing (30' Diameter) but Mulholland (Who was the projects original engineer) came up with a better solution; He had the break fixed, and then filled the tube with water (shutting the valves at the far end) and then used the pumps at the front of the Aqueduct to pressurize the water, which expanded the iron tubing back out to almost original shape.
