Saudi Arabia's Impossible Water System SHOCKED American Engineers

Saudi Arabia has almost no permanent rivers — yet millions of people turn on a tap every day and fresh water flows.

How?

The answer is one of the largest water engineering systems ever built.

In this DiscoverTube documentary, we explore how Saudi Arabia transforms seawater into drinking water, then pumps it hundreds of kilometers across the desert through more than 14,000 kilometers of pipelines, massive pumping stations, reservoirs and intelligent monitoring systems.

We go inside the science of reverse osmosis, explain how enormous desalination plants remove salt from seawater, and follow the remarkable journey that carries fresh water uphill toward inland cities such as Riyadh.

But producing water on this scale comes with major challenges: enormous energy demand, membrane biofouling, concentrated brine and the need to protect surrounding marine ecosystems.

That is why researchers at KAUST and engineers across Saudi Arabia are now developing more efficient membranes, energy-recovery technology, AI-powered monitoring, renewable-powered desalination and even methods for recovering valuable minerals from brine.

Saudi Arabia didn’t have a major river.

So it effectively built one.
