Saudi Arabia Is Building The World's Largest Artificial River In The Desert

Saudi Arabia has a water problem it's trying to solve by building the world's largest artificial river in the desert. This gigantic mega project is already under and costs a staggering $500 million dollars. Why is Saudi Arabia trying to build this giant artificial river mega project, what will they use it for and how exactly are they going to build it? Today we look at the insane engineering behind the project and if it will actually work.

Is this the coolest mega project in Saudi Arabia right now?

A “River” ? An underground pipe sounds more like a “pipeline” to me…

This will work as long as you add forests to reduce winds and help provide conservation of the aquafer.

This is more profitable to humanity than spending money on weapons for destruction of humanity championed

One question. What happens to the enormous quantity of brine produced as the byproduct of desalination?

[lets.build.cool.things]

Fun fact: Libya now currently has the worlds largest man made underground rivers. 🇱🇾

Why does every Middle Eastern country go for the world's largest?

Now, if Saudi Arabia starts planting Mangrove forests on their coasts, build more Solar plants to produce all their electricity, using the brine from the saline convertion as energy storage, they might be up to something.
But this pipeline system is NOT a river. Misleading title.

Video shows a trench for laying two pipeline, but still talking about "river". These would be networks of pipelines, built around KSA to deliver water for agriculture. Lybia already has similar networks, unless USA bombed them.

Pretty cool! Glad to see Saudi Arabia is a leader in desalination! California could benefit from mirroring those systems.

Desalination on this scale will result in the production of an enormous volume of brine. The diagrams showed the filtrate coming out of the processes, but the other fraction, known as retentate is typically 40-60% of the total volume. As you attempt to reduce the retentate volume (thereby increasing the salt concentration), you non-linearly increase the energy demand on the RO system. So they will be dumping all this brine back into the environment, and there will be consequences. I don't mean to suggest they can't or shouldn't do this.. I understand that this strategy enables millions to flourish in Saudia Arabia. I would like to see some acknowledgement of the donwsies as well as hear their plans to mitigate those impacts (if any).

Amazing and impressive? Yes! Sustainable? That's still debatable... If its solar powered and using advanced water conservation techniques? Then yes! If it's oil powered, wastes water and doesn't use industry best practices? Then it's a fool's errand... Hopefully it's more of the former and less of the latter...

Was this written by the Saudi marketing department?

[lavolpe]

Take the energy from massive solar plants, and lay the brine in big pools in the desert to produce salt as the last water evaporate. You get return on investment when you become net exporter of salt while at the same time not puttign the brine back to the sea, destroying eco systems with too salty water.

Good projects and great thinking ahead for the FUTURE!!

[oldreddragon]

I wish them success and hope they will share their experience with other Nations.

[maikelwarmerdam]

Where does the brine go? Usually they pump it back into the ocean where its very bad for sealife.

[edwilko]

The USA states like Arizona and California should be investing in desalination projects ❤

[marioxerxescastelancastro]

An underground pipe is not a river. Thumbs down for misleading title.

[adwanalshammari]

Not mentioned most of the project has already been completed and operational now 🤲. Alhamdulillah
