You’re standing in the middle of the Arabian Peninsula. It is 115 degrees Fahrenheit. There are no permanent rivers. No lakes. Just endless sand and rock. Yet, when you turn on a tap in a skyscraper in Riyadh or a hotel in Jeddah, water gushes out. Ever wonder how that's even possible?
Honestly, it shouldn't be.
Saudi Arabia is one of the driest places on Earth, yet it has one of the highest per capita water consumption rates globally. We’re talking about 260+ liters per person every single day. The math doesn't add up until you realize the Kingdom has basically turned water production into a high-tech industrial operation. They don't just "find" water; they manufacture it.
The Desalination Powerhouse
When people ask how does Saudi Arabia get water, the big answer is the sea. Specifically, they take the salt out of it. Saudi Arabia is the world leader in desalination. They produce over 11 million cubic meters of water every single day. That is enough to fill roughly 4,400 Olympic-sized swimming pools every 24 hours.
The Saline Water Conversion Corporation (SWCC) is the giant behind this. They operate a network of over 30 massive plants along the Red Sea and the Arabian Gulf. For a long time, they used a process called Multi-Stage Flash (MSF) distillation. Think of it like a giant kettle. You boil the seawater, catch the steam, and let it condense into pure water. It works, but it eats energy for breakfast.
Lately, there’s been a massive shift.
Moving Toward Reverse Osmosis
The Kingdom is pivoting hard toward Reverse Osmosis (RO). Instead of boiling water, RO uses high-pressure pumps to shove seawater through tiny membranes that catch the salt. It’s way more efficient. New projects like the Jubail 3A and 3B plants are massive RO facilities. By 2026, the goal is to have the private sector handling a huge chunk of this, pushing capacity even higher while trying to keep costs down.
Mining "Fossil" Water from the Ground
Here is the part that most people find a bit scary. About 40% of the country's water still comes from the ground. But this isn't a normal well that refills when it rains.
They are tapping into "fossil" aquifers.
These are deep underground pockets of water that were trapped there thousands of years ago when the region was actually green and lush. Because it almost never rains enough to refill them, this water is non-renewable. Once it's gone, it’s gone forever.
In the 1980s and 90s, Saudi Arabia used this water to try and become a global wheat exporter. It worked for a while, but the cost was astronomical—not in money, but in lost resources. They’ve since scaled back agricultural wheat production to save what’s left of the aquifers, but the extraction still happens for other crops and local needs. Some estimates suggest that over 80% of these initial reserves have already been pumped out of the ground.
The Secret Ingredient: Treated Wastewater
You might not want to think about where the water in your toilet goes, but in Saudi Arabia, they’re obsessed with it. It's a gold mine.
Basically, they can’t afford to waste a single drop. The "Treated Sewage Effluent" (TSE) market in the Kingdom is one of the fastest-growing in the world. They’ve realized that it is way cheaper to treat and reuse wastewater than it is to desalinate new seawater.

- Cost of Desalination: High energy, high cost.
- Cost of TSE: Relatively low, and the "raw material" is always available.
Right now, they use this treated water for things like watering city parks, cooling industrial machinery, and some irrigation. The "Green Riyadh" project, which aims to plant millions of trees to cool down the capital, is basically powered by recycled water. The goal is to reach 100% reuse of municipal wastewater by 2025-2026. If they pull it off, it turns a linear waste system into a circular one.
Is NEOM Building a Solar Dome?
If you've been following the news about NEOM—that $500 billion "city of the future"—you might have heard about the Solar Dome. It sounds like science fiction.
The idea is to use a massive glass-and-steel dome to concentrate solar energy and evaporate seawater. It’s supposed to be 100% carbon neutral. While the pilot projects are still in the works, it represents the Kingdom's "hail mary" attempt to decouple water from oil. Right now, desalination uses a massive amount of the country's domestic oil and gas. If they can switch to solar-powered water production, they can save that oil for export or other uses.
The Role of the Qatrah Program
Technology is only half the battle. The other half is human behavior.
The Saudi government launched the Qatrah (which means "drop") program to basically tell everyone to stop wasting water. They’ve introduced new tariffs, mandatory water-saving fixtures for buildings, and massive public awareness campaigns. It’s a tough sell when people have been used to heavily subsidized water for decades, but the reality is hitting home.

What This Means for the Future
Saudi Arabia’s water strategy is a high-stakes gamble on technology. They are literally building a civilization where nature says one shouldn't exist.
If you're looking at how this affects the region or your own perspective on resource management, here are the real-world takeaways:
- Diversification is key: You can't rely on just one source. The mix of desalination, groundwater, and recycling is what keeps the taps running.
- Energy and Water are linked: In the desert, water is energy. If you run out of energy, you run out of water.
- Conservation is no longer optional: No matter how many plants you build, a growing population with high consumption will eventually break the system.
The next step for the Kingdom is perfecting "Zero Liquid Discharge" (ZLD) technology. This would allow them to extract minerals like magnesium and lithium from the salt brine left over from desalination. Instead of pumping the salty sludge back into the sea (which hurts the environment), they want to mine it for profit.
The reality of how does Saudi Arabia get water is a story of extreme engineering. It’s a glimpse into what many other countries might have to face as climate change makes fresh water even scarcer across the globe.
Actionable Insights for Water Management
- Monitor Local Groundwater: Even in non-desert climates, aquifers are being depleted faster than they recharge. Check your local water board reports to see the health of your regional "savings account."
- Invest in Greywater Systems: If you’re a homeowner or business owner, look into greywater recycling. Reusing laundry or shower water for gardens can reduce freshwater demand by up to 30%.
- Support Efficient Desalination Research: Keep an eye on companies specializing in "Low-Energy RO" membranes. These are the components that will make water affordable in the coming decades.
