Dubai Introduction Part 1

Dubai 30years ago, most of this was desert.

There's a glittering Metropolis the fastest growing desert city on the planet.

When I first came here with this existence applause one big building a city like this in one of the hottest inhospitable places on earth, seems impossible.

So how did engineers do it?

To find out we will strip the city to reveal its secret inner workings and expose the ingenious technology that allowed engineers to build this jewel in the desert.

ATM and Dubai temperatures will soon reach over 100 degrees Fahrenheit but Dubai's 2 million citizens don't have to worry about the scorching heat or know much about the technology that keeps them alive.

The city's most visible techno Marvel is the Burj Khalifa.

Half a mile high, almost twice as tall as the Empire State Building. It's the tallest skyscraper in the world.

Tearing the way it's glass skin reveals a hive of activity up to 35,000 people can live and work in this gigantic greenhouse.

What stops them from being roasted alive ?

The short answer water 200,000 gallons a day for this building alone.

Finding this much water in one of the driest places on earth was a huge challenge. When the building boom began 40 years ago.

There are no rivers in the city and hardly any rain yet Dubai is a wash with water. How is this possible?

The answer lies 50 miles to the east in the hedge our mountains. geologist Catherine good enough knows this area like the back of her hand.

She's part of a team that's producing an extremely detailed geological map of the United Arab Emirates. It covered pretty much the whole of the UAE

Then something like 30,000 observation points we have to drive every track we have to try and drive a race to the desert we've had to climb a mountain which is a mock up what is basically had to cover the whole venture on her mapping mission Catherine discovered signs that the Emirates word always is dries today

here in this deep mountain valley. This woody we've got evidence of water everywhere that we like the body itself is V shaped. That pretty much tells you that the valley has been carved out by flowing water and then we can see all the rocks around here have been smoothed off just plaintiff animated by the action of water.

2 million years ago Dubai was a really wet place

where the skyscrapers Dan today mighty rivers flowed through a less fertile floodplain but over time temperatures roads.

The rivers ran dry as the desert swallowed the area. The water seeped away but it didn't all vanish. Some of it moved underground and today it's still flowing through the rocks deep under the city.

What what is the what is of course, it's flowing really quickly. But once it gets underground, it starts flowing around between sand grains and pebbles and so moves much more slowly. And also, of course, it kind of every is easily because it's not on the surface so that water can stay there in the ground for thousands years. And that provided the original source of water for the ancient water. Kickstarter, Dubai's explosive growth but it's no longer enough to quench the thirst of this expanding metropolis.

Today, the city relies on huge dissemination lands that turn seawater into fresh water.

But pumping the water around the city and into skyscrapers, like the Burj Khalifa is a formidable challenge engineer, john sweats has overseen the installation of water networks into many of the city's towers.

If we're on were able to just look at the water distribution infrastructure, one would see a myriad, almost like a spaghetti bowl of pipes. Water is distributed to every corner at every floor at every level,

using a single giant pump to play water right today.

top of a building, as tall as the Burj Khalifa would be dangerous.

Forcing water this high up takes extreme pressure

which could make the pipes explode.

So engineers pump the water up in stages first to a huge reservoir on the 14th floor to a series of 200,000 gallon tanks until it reaches the top of the building.

Then the water simply flows back down under its own way almost a quarter million gallons of water a day pass through the building enough to keep its inhabitants happening.

engineers use this clever to Technology all over the city.

Today John's team is finishing up the water network in the princess tower, the world's tallest residential building.

They must push water up 100 floors more than a quarter of a mile.
