00:00No rivers, no lakes, barely any rain.
00:02Qatar sits in the highest water stress bracket on the planet.
00:05Yet the taps never run dry, and it makes more water than it uses.
00:08But it all comes down to one ingenious strategy that makes the impossible possible.
00:13Let's break it down.
00:14Turning seawater into drinking water.
00:17Qatar could not rely on nature for water, so it built its own supply.
00:21The answer it leaned on is desalination,
00:23which means taking seawater and removing the salt until it is safe to drink.
00:27How do we overcome that limitation?
00:28Is that we use desalination to provide all of our drinking water, all the water that we use.
00:35Qatar's first plant opened in 1953 and made only about 682 cubic meters a day.
00:40As gas money grew, so did the plants.
00:42Early ones used heat to boil seawater and catch the clean steam,
00:46a method called thermal distillation.
00:48These plants sat next to power stations,
00:50so the leftover heat from making electricity could help boil the water too.
00:53The real jump came in the 2000s and 2010s.
00:56Around 2016, Qatar added large plants that push seawater through fine membranes under pressure,
01:02a method called reverse osmosis, which uses less heat.
01:04Today, desalination supplies almost all of Qatar's drinking water, more than 99%.
01:09Groundwater is now saved mostly for farms.
01:12The scale is large.
01:13Plants can make around 500 to 540 million gallons a day,
01:17while daily demand sits closer to 400 million, so there is spare water in the system.
01:21More is on the way, including a new part of the Ra's Abu Fontes plant.
01:24The Umm al-Haw plant alone makes more than 600,000 cubic meters of water a day,
01:29while also making electricity.
01:31Qatar Electricity and Water Company runs much of the production,
01:35and Karamah moves it to homes.
01:36The work is not easy.
01:38The gulf is very salty, often 45,000 to 57,000 parts per million,
01:42and it is warm and full of tiny sea life that clogs the machines.
01:45So researchers at QERI keep testing better designs and stronger membranes,
01:49some aiming to cut the energy used by up to 40%.
01:52Cheap natural gas is what makes all of this possible,
01:54and solar power is slowly being added to make it cleaner.
01:57Qatar now treats these plants as critical national assets.
02:00But to see why they matter so much,
02:02you have to look at how little water the country started with.
02:05A country without water
02:07Qatar is a small piece of land that points out into the Arabian Gulf.
02:11It has no rivers and no lakes, and the rain that falls each year is small,
02:15only about 70 to 100 millimeters,
02:17and much of that dries up before it can be used.
02:19Summer days climb past 45 degrees Celsius.
02:22We have no lakes, no rivers.
02:24The only natural water is underground,
02:27held in old stores called aquifers.
02:29Nature refills them with only about 50 to 60 million cubic meters a year.
02:33But for years, farms and cities pumped out far more than that,
02:36often 200 to 300 million cubic meters a year.
02:39So the water table kept dropping, and what was left turned saltier.
02:42They're not being replenished at the same rate that they're being extracted.
02:46Put simply, each person in Qatar had only about 20 to 50 cubic meters of natural renewable water a year,
02:52far below the 500 mark the world uses to flag severe scarcity.
02:56That places Qatar in the highest bracket of water stress on the planet.
03:00It was not always a modern problem.
03:02Back in the 1950s, people in Doha drew water from desert wells,
03:05then boiled and filtered it,
03:06and much of the supply arrived by tanker truck.
03:08Then oil, and later the giant Northfield gas reserves, changed everything.
03:12Money poured in, the country grew fast,
03:15and the population jumped from a few hundred thousand to more than 2.5 to 3 million.
03:19With that growth came heavy water use,
03:21once among the highest in the world at 500 to 600 liters per person each day.
03:26Yet most people never saw a shortage, because the taps kept running.
03:29The crisis stayed hidden,
03:30even as the need for water raced past anything nature could give.
03:34Building a Backup.
03:36Desalination closed that gap and gave Qatar its water.
03:39But making water is only half the job.
03:41If the plants ever stopped, the country needed a cushion.
03:43As late as the early 2010s,
03:45Qatar held only about 48 hours of spare water,
03:48and by some counts just one to three days.
03:50Its plants all sit on the coast,
03:52where a fault, a dirty intake, or a regional standoff could cut supply.
03:56The danger was not just theory.
03:58Qatar had already lived through a sudden shock when its borders were closed off.
04:01And for the state of Qatar, when it had its political issues with its neighbors between 2017 and 2021,
04:08where global supply chains or access to global markets were completely disrupted.
04:13That lesson pushed Qatar to treat water like a shield it could not afford to drop.
04:16The country launched the Water Mega Reservoirs Project,
04:19a plan costing around $4 billion.
04:21Starting around 2015 and coming online from 2018,
04:24crews built huge concrete tanks at inland sites like Umm Baraka,
04:27Umm Salal, Radet Rashid, Abu Nakla, and Al-Tumama.
04:30Reports count 15 to 24 giant tanks,
04:33and some are so big they earn Guinness World Records.
04:36The goal for the first phase was about seven days of water for the whole country,
04:39close to 10 million cubic meters,
04:41with a later phase reaching toward 2036.
04:44Tying it all together is a web of about 650 kilometers of wide pipelines,
04:48so water made at any plant can flow to any tank.
04:50The system works in layers.
04:51Plants make water all day.
04:53Mega reservoirs hold the bulk backup,
04:55and smaller local tanks handle daily peaks.
04:57Automated pumps and constant checks keep the taps running to World Health Organization standards.
05:03Qatar also drove its pipe leaks down to only about 4.5 to 5.3%,
05:08which is strong by world standards, using smart meters and steady repairs.
05:12There are even plans to store water deep underground to build a reserve lasting around 90 days.
05:18Wasting nothing.
05:19Qatar also learned to squeeze more out of every drop.
05:22When people flush and drain water at home, it does not just disappear.
05:26That we can recycle, treat that water, reuse that water.
05:28That used water is cleaned at treatment plants,
05:31and sent back out for jobs that do not need drinking quality water.
05:35A lot of that water is used for outdoors, like watering trees.
05:40Today, about 98% of the wastewater Qatar collects is treated and reused,
05:44adding up to billions of cubic meters over the years.
05:47This treated water keeps parks green, feeds crops grown for animals, cools buildings,
05:51refills lagoons for later use, and is even pumped back underground to help the aquifers.
05:55The Public Works Authority, known as Ashkel,
05:58expanded the sewer and drainage network so much that it more than tripled in length in some years.
06:03Smart sprinklers that red the soil have cut water use in some parks by about 25%.
06:08On the saving side, Karama launched the Tarshid campaign back in 2012 to teach people to use
06:13less water and power. Rules now stop drinking water from being used to cool buildings,
06:17pushing that job onto recycled water instead. And to protect the shrinking groundwater,
06:21a new water law tightens the rules on drilling wells, while farms move to drip lines,
06:26greenhouses, and crops that need less water. These steps are working though not perfectly.
06:30Groundwater pumping has slowed in some recent years, yet the country still takes out more than
06:34nature puts back. The gap is smaller but it has not closed. Even so the idea has shifted.
06:39Water is caught, cleaned, and sent around again, which takes pressure off the plants and the storage
06:43tanks alike. The rules and the road ahead. None of this holds together without someone in charge.
06:49Karama runs the making and moving of water, while Ashkel handles wastewater and drainage.
06:54Above them sits Qatar National Vision 2030, which puts saving resources at the center of the country's
06:59plans, backed by national strategies that set targets for storage, reuse, and cutting losses.
07:04In 2025, Qatar passed Water Law No. 23, which pulls scattered rules into one book,
07:10guards the groundwater, plans for emergencies, and pushes for more reuse.
07:14Research drives the next steps. The team at QERI works on better plants,
07:18membranes built for the Gulf's salty water, digital tools that spot leaks fast,
07:22and ways to handle the leftover salty water, called brine. The results speak for themselves.
07:28Nearly everyone in Qatar now has safe drinking water and sanitation. The country makes more water than it
07:33uses on an average day. Its stored backup has grown from one to three days into a much longer cushion.
07:38Its leaks are low, and almost all of its wastewater is reused. The job is not finished.
07:43Farms still pump more groundwater than nature replaces. Desalination burns a lot of energy and
07:48returns hot, salty brine to the Gulf, which stresses sea life. Cheap, subsidized water makes it hard to
07:53get people to cut back. And the plants all sit on one coast, which is a risk. On top of
07:57that,
07:57a warming climate will make heat, evaporation, and demand worse. So the road ahead means more plants,
08:02more storage, smarter systems, more solar power, stricter rules, and research into reusing brine
08:08instead of dumping it. Qatar's story shows that a dry country with money and focus can build its
08:12way out of extreme water scarcity. It is not cheap, and not every nation can copy it, but the lesson
08:17is clear. Demonstrating for the world how a sustainable future is in arid environments.
