A joint venture between McCarthy Building Company Inc. and Jacobs has been chosen to design and build a $160 million desalination expansion project in Southern California, the companies announced
Will treat salt water in the West Coast Groundwater Basin in the southwestern part of the Los Angeles Coastal Plain and establish a more reliable local drinking water supply for the district's residents, doing away with the need to import water.
The basin provides groundwater, the district said, to about 11 cities and unincorporated areas of Los Angeles County.
In addition, the project will increase the drinking water production capacity of the Robert W. Goldsworthy Desalter Facility, also located in Torrance, by nine million gallons per day.
This is possibly a first-of-its kind nano filtration and reverse osmosis treatment for a municipal brackish water facility, according to the joint venture
The expanded facility is expected to enter full-scale production in 2027
Love to see it! Secure that water production!

I wonder who is putting up the cash? Is it California or the US? In any case, the taxpayers are paying upfront for the company to run profits later, aren’t they? I know that they are sitting in the middle of a desert area in LA, so they have to get their water from one place or another.

I would be surprised if they got Infrastructure bill funds

The problem is there is no money for it because they are running the tax paying companies out of the state. Then they have spent what they had on things like homes for the homeless at 600K each. I don’t think the US taxpayers should bail them out, either. Also, they seem to be big on wasting the water that they have whilst taking it from the farmers in the Central Valley.

From what I know about desalination, ROs take a huge beating from the salt. Did they say in the article what would happen after they process all that brackish water in the groundwater? How are they going to keep the saltwater out indefinitely?

The article doesn’t explain what they are doing to with the brackish water. I assume they will dump it in the ocean

It would be interesting if they reprocess the reject and make sea salt out of it. That way there wouldnt be any waste!

The amount of brackish water that’s produced is huge. The operation to reclaim the salt would be uneconomical. I am sure salt mines can produce much more salt per kg of energy spent than a desalination plant.

That is probably true, but they could just put it on a pad and let the sun dry it out. It is a lot of brackish water, though. Do you know what is involved with the nano filtration?

Why don’t they just go from the ocean and back to the ocean with the concentrated salts? I think it is brackish because the ocean water is seeping into the aquifer, somehow.
