00:00How many times have you had a camera crew film you when you were in a sauna?
00:05I'm a father to two beautiful daughters.
00:08I'm also a husband, a son, a cyclist, a citizen.
00:15I should try that. What could possibly go running?
00:18Ow! We've got stones falling on our heads.
00:21When our most precious resource is draining away...
00:30Wow, there's a lot of trash here.
00:32In this place, a lot of criminalization is full.
00:35The unfairness is striking and it hits you in the gut.
00:40We have to reclaim what's lost.
00:43Raw suites.
00:45We take what we have and we are happy with it.
00:49Groundwater rejuvenation is crucial to the city's water sustainability.
00:53For today and for tomorrow...
00:57Such a happy feeling.
00:58For everyone.
01:00Inmediatamente puede cambiar el giro del mundo.
01:03The most futuristic thing in water, this is it.
01:07I'm Nikolai Costa-Waldau.
01:09My leg! I love it!
01:11And this is an optimist's guide to the planet.
01:23So it never rains but it sure as hell looks like rain.
01:26If not rain...
01:27Lima is the largest city in Peru, built in the middle of a desert.
01:37It gets less than an inch of rain a year, which is hard to believe.
01:41How is this not rain?
01:42How is this not rain?
01:44How is...
01:45Look up!
01:46This is rain!
01:47I know!
01:48It feels like rain, I guess.
01:49Is it misty?
01:50Is it misty?
01:51Is it misty?
01:52Is it misty?
01:53Is it misty?
01:54Is it misty?
01:55Lima is in the desert.
01:56But...
01:57Because Lima is close to the Pacific.
01:58The wind came from the Pacific, and gets stuck with the mountains.
02:13mountains and that's why it's a lot of a lot of moisture but never rain now we
02:24are gonna go up in the mountains it is where poor people live usually in other
02:30countries of the hills was the most expensive on the top of the mountain
02:34there is a big wall dividing the rich people with poor people we're meeting a
02:41guy named Abel who lived in a part of Lima similar to where we're going but there was
02:47no electricity there was no plumbing there was no water we need water that's one of the
02:52basics of life and he thought there must be a way to collect this water this moisture in the air
02:58this is a steep hill oh yeah a homemade road
03:11Abel hola hola hola this is my wife okay hello how are you I thought we were doing a story about
03:33about dryness no he said where's he said okay he said I've never seen so much water on a place that
03:43doesn't rain he said I've never seen so much water in a place where it doesn't rain
03:48so it's this weird irony the people they're soaked every morning but you
04:02live in a place with no access to water no solamente is a key cerca de dos millones de
04:10personas viven así en el cinturón wow hay casi cinco mil asentamientos humanos que no
04:17tienen agua y desagüe este lugar se llama asentamiento los pinos allá está la frontera entre la
04:29molina que es un distrito de las familias ricas y hasta el lado de esta gente humilde entonces
04:36allí se ha construido una línea un muro así como la muralla china el agua no está bien compartido entre
04:46todos hay camiones cisterna que traen de abajo y venden el metro cúbico aquí ellos pagan más de 15
04:56dólares el metro cúbico y en la ciudad pagan un dólar esto es ahí está la humedad ahí está aunque está
05:07pasando ya está ya aquí es the humidity is here you can see it i mean it's everywhere
05:12it's everywhere god damn it you put on the nice shoes today
05:19how did you get the idea of collecting the moisture in the air
05:30cuando yo llegué a lima ya más o menos tendría mis 20 años entonces viví como aquí en arenal y sin
05:41agua yo lo cerqué con mayas raché todo con esas mayas raché lo he cercado todito entonces una noche
05:50llegué de mi trabajo había esta neblina había bastante gotera de las mallas porque las mallas
05:57que haya bastante el agua siempre me ha traído este tema de ayudar y tener algo por de agua en casa
06:06estudiamos hoy analizamos que material podría captar mucho más de lo que puede captar estas estas
06:14nets hoy día vamos a entregar 80 nets a la comunidad vamos a llevar arriba para instalar
06:25it's okay let's get to work let's go let's go you wipe my lens the lens is collecting water
06:32vamos a sacar los materiales y vamos a llevar al cerro hola was a very important part of this that it
06:42had to be very cheap what year did you put the first net up what year did you put the first net up
06:5740 años
06:5840 años
06:58vamos
07:02okay
07:03how many have you put up around lima how many in that's in lima más de mil
07:08what is it up we'll go up here yes i oh we're over here
07:16that's where the rich live in the fog that's ironic so this used to be a wall
07:26this is official riches area the kids come here to do viking while the purists build the houses on the
07:38border señoras pasen a este lado porque en cualquier momento viene la bicicleta y les va a
07:44chocar the poor people on this side and then you have the mountain bike for entertaining yeah for
07:50entertaining yeah is that part of the wall is that something different esa era parte del muro no
07:55exacto sí exactamente hace dos años este existía ese muro pero a través de un juicio perdió el distrito
08:05de la molina y lo sacaron y ahora ha sido derrumbado y para que siga esta este muro lo hemos
08:16construido estas mallas or remove the wall physically ellos mismos la comunidad eso se llama el muro de la
08:26vergüenza hoy en día se va a llamarse el muro de la amistad y de la esperanza nicolai sí entonces
08:35aquí hay que poner otra malla ok you want me to just climb up there oh my god where's the clip
08:42falta el gancho no this need the uh the hook it's all and then I put it like this yes
08:50oh my god I'm up high now uh-huh ok aplaudan
09:03can i get a job here can i get a job here you're hired you're hired
09:13it's working no the water is working oh yeah
09:24I was just gonna wash my hands
09:29this one net how much water does this provide de doscientos a cuatrocientos litros wow
09:39much water in one in 24 hours in one day how many people get water from all the nets
09:46in lima aproximadamente 60 mil familias que gozan de este sistema so the water is collected it runs
09:55through the pipes it goes down to these tanks and from there uno para consumo humano otro para huerta
10:03para el huerto comunal y el otro para criar cuyes ahora vamos a ver
10:09agua
10:14ahí está ahí está agua
10:17ahí está el agua
10:19the water from the nets fantastico you don't want to waste any more
10:40wow mace tenemos el maíz las calabazas
10:45production y eso nos alimentamos no con los vecinos con lo que ahí se comparte

11:43They were named by that princess.
11:45Princessa, Khaleesi.
11:47You're a princess.
11:49You're a princess.
11:51Okay, well, there you go.
11:53That's a small world.
11:55What do you think of these nets?
11:57I think it's good because here, especially,
11:59there's not so much water.
12:01Sometimes the water truck comes from here,
12:03the car that brings the water to this place
12:05and sometimes it costs money.
12:07What do you want to be when you grow old?
12:09Do you have an idea?
12:11Do you want to be a painter or a police?
12:15Police or a painter or a police?
12:19Or you can be both.
12:21I draw in the paintings.
12:23I draw in the paintings or types of clothes.
12:27So you said you wanted to be an artist or a police officer.
12:30Why a police officer?
12:31Why would you like to be a police officer?
12:33To be something just with some people,
12:37because in this place,
12:39there's a lot of people.
12:41There's too much in this place.
12:42There's murders, robes.
12:44Descuartization.
12:46Mal.
12:47Trist.
12:48Got it, yeah.
12:49Sinseguridad.
12:51Oh.
12:52I hope you will see a better future for you
12:54when you grow up.
12:56Thank God we have dogs and cats.
12:58They can make us happy.
13:02When you call a show an Optimist's Guide to the Planet,
13:08it's easy to then imagine it being some kind of soft, happy-go-lucky.
13:15Everything is just, you know, stay positive.
13:17Everything is going to be good.
13:19My optimism is, I think it's grounded in meeting kids like that.
13:26How they see their circumstances
13:28and being very aware of the unfairness of these circumstances,
13:33that they live here.
13:34They have dreams, like our kids.
13:37Yeah.
13:38They do believe in the future.
13:42That's the thing that gives you hope.
13:44But it is, it is so ridiculous that something as simple as access to water
14:00is, it is so difficult for so many people.
14:05That two million people here, the unfairness is striking in it.
14:10It hits you in the gut.
14:16You got it?
14:17No.
14:18Okay.
14:19You got it?
14:20No, you got it.
14:21You got it?
14:22Yeah, man.
14:23You got it?
14:24Oh, you got it?
14:25Just a second.
14:26No.
14:27Okay.
14:28You're not loved, no.
14:29You're not loved.
14:30the Pinos of San Gabriel Alto,
14:32of all my heart.
14:34I am very grateful for your visit.
14:36I hope this is an experience
14:38for us and for the world
14:40that you see.
14:54The fact that you are taking action
14:56is changing people's lives.
14:58There is an immediate solution
15:00that can change the world's turn.
15:02Not only in Peru
15:04the need of water,
15:06but also in the world.
15:08There are many rivers
15:10that are drying up.
15:12In the world, more than
15:142.000 millions
15:16of people don't have water.
15:18We see that
15:20there is a lot of water in the space.
15:22The work is how to capture
15:24that water.
15:28Water is the most important ingredient
15:30for life,
15:32for people,
15:34for communities everywhere.
15:36But in our rush for development
15:38we often take it for granted.
15:40This is India's version
15:50of Silicon Valley.
15:52A city of contradictions
15:54where ancient traditions
15:56meet cutting edge innovation.
15:58And at nearly 15 million people
16:02it's one of the fastest growing cities
16:04in Asia.
16:06It's also a place
16:08where the water supply
16:10is on the brink of collapse.
16:12Bengaluru is known as
16:14the city of a thousand lakes.
16:16A lot of lakes
16:18have been raised
16:20because of construction,
16:22because of the city growing.
16:24And then the rest has just been used
16:26as a dumping ground
16:28for trash and sewage.
16:30I think there's so many different ways
16:32that you have to deal with this
16:34because they need to reclaim
16:36the lakes for drinking water.
16:38I'm going to see three groups.
16:40Each playing a part in the solution
16:42to Bengaluru's water crisis.
16:46First, I'm on my way to meet
16:47a gentleman called Anand
16:49and he is a project
16:50where they're cleaning up lakes.
16:56Wow.
16:57There's a lot of trash here.
16:59Oh my God, look at that.
17:05This is leading to the lake.
17:19Hello, Anand.
17:20Hello.
17:21Warm welcome to you.
17:22You're cleaning a lake?
17:23Yes.
17:24It's all going on.
17:25Work.
17:26Yes, happening now.
17:27It's a dirty lake.
17:28It's a dirty lake.
17:29Dark lake.
17:30And you can see the situation.
17:32It's massive, right?
17:34You can see a slurge.
17:36There is a fecal matter of people,
17:38food, grain, oil, grease, plastic.
17:40Everything is mixed in.
17:43In Bengaluru?
17:44Yeah.
17:45Why did they allow
17:46all these lakes to be destroyed?
17:48Around 20 years back,
17:49nobody realized.
17:50The city started growing very rapidly.
17:53A lot of people started migrating
17:55from village to city.
17:56Uh-huh.
17:57But education, business, work.
17:58So nobody thought that
17:59where exactly our sewage is going.
18:00No, no.
18:01Right?
18:02There is no proper treatment system.
18:04Yeah.
18:05All sewage is going to the lake.
18:08I'm a lake conservationist.
18:09I resonate with them.
18:11And I bring back
18:12the last glory of the lakes.
18:14How long have you been doing this?
18:16I'm doing the last 10 years.
18:18I was working with one of the companies,
18:20automotive and aerospace industry.
18:22Okay.
18:23Good salary, parks, happy life, everything.
18:25One day I read a newspaper.
18:27Bangalore will become a zero water city.
18:29By 2030, Bangalore, no drinking water.
18:33After reading that, somehow I felt uncomfortable.
18:36What will be the situation of people?
18:38Where can they drink water?
18:39How can they survive?
18:40Then I started researching one of the lakes nearby.
18:44One side full of sewage.
18:46When I was walking to, you know,
18:48just to check the lake,
18:50I fell down into that pit.
18:52It was so dirty, so smelly.
18:55I stay in an apartment community
18:57when security did not allow me inside.
19:00Then I decided, let me do it.
19:03I wanted to make one lake and show it to people.
19:06First lake I originated in 45 days.
19:09Wow.
19:10That lake made me to continue this journey full life.
19:13I left my corporate life, everything.
19:15I am in lake.
19:16I enjoy it.
19:17I'll show you.
19:21You can see here.
19:23What is going on?
19:24It is called excavation.
19:29Job is remove dirt water, remove the sludge completely,
19:34reach a fresh soil.
19:35Wow.
19:36And then you're ready for the big rainfall.
19:38Rainfall.
19:39Once you have this completely cleaned up,
19:42how long before it's filled up with rain water?
19:44Good night and rain, sir,
19:47the lake will get filled up.
19:49Wow.
19:50And next lake we're going to show is,
19:53after transforming,
19:54is with water, with birds, with animals, everything.
19:59Anand isn't just restoring lakes.
20:01He's reclaiming the entire ecosystem,
20:04making sure any untreated sewage doesn't contaminate the lakes anymore.
20:09This is where you don't want to take the wrong step.
20:14Sewage.
20:15Sewage.
20:16Yeah, that's what I mean.
20:17This is all sewage.
20:18Yeah.
20:19You can see full black.
20:21Oh my God, yeah.
20:22This is the canal.
20:24Whatever sewage used to come inside the lake, it has been diverted.
20:29It never mixes with lake.
20:31It never mixes with lake.
20:32Yeah.
20:33All these aquatic plants will absorb excess nutrients,
20:36then exposed to ultraviolet sun,
20:38so that anaerobic bacteria will be reduced.
20:41Anand's system replicates many of the functions
20:44of a sewage treatment facility.
20:46But he's using plants,
20:48interconnected ponds,
20:49and the UV rays of the sun
20:51instead of machines and holding tanks.
20:53So you guys planted all this?
20:57Yes.
20:58They're all planted by me.
21:00That's your three.
21:02More than 15,000 houses.
21:04Sewage is flowing here.
21:06It's coming here.
21:07No smell?
21:08Yeah.
21:09So without sewage treatment plant,
21:10without chemical,
21:11without machineries,
21:12without electricity,
21:13soil, water, botanical, sun can do magic.
21:16This is what my message.
21:18That is magic.
21:19Yeah.
21:20Wow.
21:21Look at this.
21:22See here.
21:23Titanic.
21:25You are...
21:29Love it.
21:30My neck.
21:31You are, Jack.
21:32My neck.
21:33I love it.
21:34Thank you, Jack.
21:37It's beautiful.
21:39No words.
21:40I love my lake.
21:41It's the largest lake of me.
21:4384 acres.
21:4484 acres.
21:4584 acres?
21:46Yes.
21:4740 hectares.
21:48See?
21:49With full of water.
21:50See?
21:51Wow.
21:52That's beautiful.
21:56See?
21:57Crystal clear.
21:58It's beautiful.
22:00No smell?
22:01No smell.
22:02Absolutely.
22:03It is not only lake.
22:04It is not only surface water.
22:07Lakes are the ecosystem.
22:09Once these lakes fill up, they percolate, they reach their ground water.
22:13So by doing rejuvenation, by cleaning this, all the ground water will have a good quality where people get it for their drinking water.
22:21If you protect small, small, small lake, it will change everything.
22:24It will change everything.
22:25Bangalore will not have a scarcity of the water.
22:27Bangalore will have a lot of drinking water because we store maximum water in the lakes.
22:32Now, government, people, all are together.
22:35See?
22:36It is not an independent job.
22:37It's teamwork.
22:38It's beautiful.
22:39See?
22:40When you came there, when the lake opens up with a full fresh water, you become emotional.
22:45Yes.
22:46You become emotional.
22:47Yes.
22:48Well, you do.
22:49You become emotional.
22:50You also.
22:51Me too.
22:58Revitalizing Bangalore's lakes is an essential step towards solving the city's water crisis.
23:05But that alone won't replenish the water supply in full.
23:09Like Anand says, it's teamwork.
23:12And the goal is replenishing the groundwater.
23:17It rains a lot here.
23:18They get a lot of rain.
23:19The problem is that because the city has grown, a lot of the water just is washed into the sewer.
23:25And then, you know, it doesn't make its way down to the groundwater.
23:29But there's a solution.
23:31It's very old technology.
23:33And I'm curious to see what that is.
23:35Oh, I see a guy.
23:38Is that Wishwanath?
23:39I'll jump out.
23:40All right.
23:43Wishwanath?
23:44Yes.
23:45I'm Nikolai.
23:46Good to see you.
23:47So, Bangalore, the city of a thousand lakes.
23:51Yes.
23:52Now I'm down to 186.
23:54On top of that, it's almost like a desert underground because the groundwater is being depleted.
23:59Yes.
24:00Is that correct?
24:01A lot of the groundwater is now run out.
24:03So, India is now the world's largest user of groundwater.
24:05Oh, wow.
24:06We use more water than the USA and China combined.
24:09Now we realize that rainwater is one of the taps that the city has to get into.
24:13And therefore, rainwater harvesting and groundwater rejuvenation is crucial to the city's water sustainability.
24:19This lake stores, let's say, 90 million liters of water.
24:22Uh-huh.
24:23But the groundwater potential is 29,000 million liters of water.
24:26Oh, wow.
24:27And if you fill that up, then the town's water requirements will be met by groundwater.
24:32And how do we do that?
24:34We came across the traditional well-digging community called the Manuwadders, who have been digging wells for a thousand years.
24:40This is the way that water was managed till the pipe water supply came into our cities.
24:44Once the pipe water supply came in, they started to lose their livelihoods a bit.
24:48Their ability to understand soil, their ability to dig, and their ability to do it absolutely safely is remarkable about the Manuwadder community.
24:57This is Shankar.
24:58Nikolai.
24:59He won't speak English, but his father, his forefathers, all dug wells.
25:06So there are 120 families in his village. All of them are well-diggers.
25:12How many projects have you got going now?
25:14We hope to dig a million wells.
25:16A million wells?
25:17A million wells.
25:18Why stop by a million?
25:20A million is just the initial goal.
25:22Okay.
25:23So we're going to see some well being dug.
25:35A recharge well, which Shankar has already finished, and one which is being dug.
25:40So both of them together.
25:41So this is the recharge well.
25:44This is Shankar's team working.
25:46Holy shit.
25:47Recharge wells take rainwater from rooftops and from stormwater drains, and push it into the aquifer.
25:57Build up the groundwater table.
26:01Just explain the procedure to me.
26:03So you mark a circle.
26:04Uh-huh.
26:05And you start to dig.
26:06And that's...
26:07That's it.
26:08You just dig, dig, dig, dig.
26:09Dig, dig.
26:10So it's gone to 19 feet.
26:12They dug this in one day.
26:14And they'll go a foot more and stop.
26:20I should try that.
26:21How do you do that?
26:23Oh, sorry.
26:24Yeah.
26:25Sit there and over your head.
26:27Yeah.
26:28There are holes for you to grip.
26:30Okay.
26:31Footsteps.
26:32Okay.
26:33So you go over here.
26:38What could possibly go wrong?
26:40Hello.
26:41Nice to meet you.
26:43Nice to meet you.
26:46Ow!
26:47Hey, guys.
26:48We got stones falling on our heads.
26:50The well diggers are advising me to tell you, not look up because...
26:54I learned the hard way.
26:57Let's get some work done.
26:59Okay.
27:06This goes back thousands of years, right?
27:07The oldest wells in India are about 6,000 years old.
27:10And as you said, you're giving employment to a lot of people.
27:12Better and better to many families.
27:14And you keep the tradition going.
27:15Beautiful.
27:18So now we're just going to clean this up and then you're going to start putting down the...
27:22Rings.
27:23Right.
27:24Right.
27:25Exactly.
27:26The chunkers is now going down to pack the sides with the stone.
27:43Oh, I see.
27:44The packing has to be very carefully done.
27:46That's what keeps the whole thing stable.
27:52Oh, so this is a finished well.
27:53This is a finished well.
27:54We get about 600,000 liters of water on the roof.
27:57And then we're putting that into the well.
27:59Oh, I see.
28:00You keep it here.
28:01You don't store it, but it will slowly...
28:03Go into the earth.
28:04Go into the earth.
28:05Yes.
28:06And if you're lucky, over time, the water will come back in the well.
28:09Because...
28:10And then you can start to draw the water.
28:11And then you can draw it.
28:12Because the earth is filled.
28:13Then you will have a well that you can actually draw from.
28:14That's right.
28:15Well, that's amazing.
28:16So, first you recharge, then you draw once the earth is filled.
28:19Recharge, and then you draw.
28:20What is your hope and belief for the access to clean water for people?
28:37It's a win-win.
28:38Well, I mean, thank you so much for allowing us to come in and see your work.
28:41It's very impressive.
28:43Thank you very much.
28:44Thank you very much.
28:45Thank you very much.
28:46Thank you very much.
28:49We need to bring the past knowledge of water management and the wisdom of water management
28:54with cutting-edge modern technology to be able to bridge the crisis that India faces with its water supply.
29:01With this work, Wish One Not has sparked a wave of innovation in restoring Bengaluru's water supply.
29:08I'm going to meet someone following in his footsteps.
29:12Thank you very much.
29:14Thank you very much.
29:20I'm very optimistic.
29:21I brought a water bottle.
29:22I was hoping you could fill it up maybe.
29:23Of course.
29:24Of course.
29:25We spoke to Wish One Not.
29:26Got it.
29:27And I know you.
29:28I interned under him.
29:29Yeah?
29:30Yeah.
29:31Yeah.
29:32His technology goes back a thousand years, thousands of years.
29:33Got it.
29:34Yours is?
29:35Yes.
29:36The highest, the newest tech.
29:37Got it.
29:38We make drinking water from air.
29:39And the idea is to...
29:40Whoa, whoa, whoa.
29:41So, slow down.
29:42That's...
29:43You sound as if that's a simple thing to do.
29:45So, above Bangalore, there is three to six billion liters of water right there.
29:49As of now.
29:50That's a lot.
29:51That's a lot.
29:52I don't know.
29:53We're standing in front of these things.
29:54What is this I'm looking at?
29:55So, this is what we call as an absorber.
29:58Absorber?
29:59Absorber.
30:00What is happening inside is there are fans on top, which pull in the air.
30:03Yeah.
30:04We have proprietary liquid salts, which readily absorb moisture from the air.
30:08And we convert that to really high quality water.
30:11We were in Lima, in Peru.
30:13Okay.
30:14We were up above the mountains.
30:16And it's a very poor community, so they put up these nets to capture the moisture.
30:21And then I thought this might be a high-tech version of that or not.
30:27So, it's a bit high-tech because the fog nets already have a lot of saturated water vapor in there.
30:32So, it's almost ready to be collected and condensed.
30:35Yeah.
30:36Whereas, we can work from 25% relative humidity and above.
30:38So, even in dry areas, we can extract water from it.
30:41If I really want the most futuristic thing possible in water, this is it.
30:46And that's who's this?
30:48Oh.
30:49We call him Yoda because we're all Star Wars inspired here.
30:52And we also named the device as Tatooine because that's the desert planet in Star Wars,
30:57where you have these devices which collect moisture from air.
31:00Huh.
31:01Okay.
31:02Yeah.
31:03Well, that's very cool.
31:04So, there's the high-tech version.
31:05That's the high-tech version.
31:06Yes.
31:07So, how is it then?
31:08Is it that simple?
31:09I'll have to show you inside.
31:10Ah.
31:11In 2016, what happened?
31:14I was doing my thesis on wastewater treatment.
31:16Uh-huh.
31:17And our campus ran out of water.
31:19Your campus ran out of water?
31:20Our college campus ran out of water.
31:22Huh.
31:23So, a lot of these personal experiences probably won't see in North America or, you know,
31:27other countries where water is abundant.
31:30We are really much driven by our own personal journeys of facing these stark realities where
31:36water access becomes a challenge.
31:38So, once the liquid salt has absorbed the moisture from the air, it comes to these three devices.
31:44And here it's heating up to about 50 to 60 degrees Celsius.
31:48Uh-huh.
31:49And all the water vapor gets collected back.
31:51And this liquid salt goes back to the absorber to again absorb moisture.
31:54So, it's a continuous cycle.
31:56We can use this salt for almost 10 years without replacement.
31:59And then, what happens to the water?
32:02Oh, yeah.
32:03I'll show you around.
32:05In this tank, which we call the formulation tank, is where we add minerals.
32:10And then, we have a final tank which then takes it to the bottling machine.
32:13Uh-huh.
32:14Oh, so this is it?
32:15Yes, this is it.
32:21And then, of course, also very important is how much can you produce?
32:24Our facility produces 4,000 yards per day.
32:28I'm curious.
32:29I want to taste what it tastes like.
32:32So, you can try this.
32:34That's very nice.
32:35Yeah.
32:40Very nice.
32:41Normal water.
32:42All right.
32:49Our largest product fits in a 20-feet shipping container as a modular product.
32:53You just drop it in at any location and plug it to an energy source.
32:57The idea is you have a machine.
33:00You don't need it to be bigger.
33:01You just need to make more of them.
33:03Exactly.
33:04We need to make a lot more of them.
33:06And it really, it scales so that it brings the cost further down.
33:09So, we really worked hard to get two cents per liter.
33:12And where there's a further pathway to go one cent per liter and below.
33:16Once you hit that price point, it really unlocks a lot of what is possible.
33:19And the funny part is, the Bangaloo's daily demand is about 1.6 billion liters per day.
33:24But the amount of water that's present in the air is more than 3-4 billion.
33:29Wow.
33:30That's more than what the whole city needs.
33:32Would there be a version where you could build water stations for people where they can go and tap?
33:37Definitely, because the idea is that these are plug-in-play solutions.
33:41You can just drop a 20 feet container anywhere in an area which has lack of excess of water.
33:47We just need to have a little bit of humidity in the air.
33:49If that is there, we could definitely bring a solution there.
33:52While we've been here, we've seen these different ways of attacking the water shortage, the prices.
33:59So, I think there has to be a mix and match.
34:01It's not just one solution, it's many.
34:04I think that this all came from Star Wars.
34:06You know, when you're just 3-4 people, it's very easy to give up.
34:17But when you have so many people believing in that vision, that just keeps you going through.
34:22But now we have a lot of data, you know, which shows that this is all possible, doable, and it's a great solution.
34:36It's a temple there.
34:37It's a temple?
34:38Yeah, that's a small temple to the gods of Saturn.
34:39Can I leave my socks on?
34:40Yeah, socks is fine.
34:41You said you're very optimistic about the future.
34:54Why is that?
34:55Because we've not realized that we have many taps to satisfy a city's thirst.
35:01Rain water is a tap.
35:02Lake water is a tap.
35:04Ground water is a tap.
35:05Air to water, that's also available to us as another one of the taps.
35:09Now, if we bring all the taps to play, there should not be a resource scarcity.
35:18Replenishing our planet's drinking water is about tapping into every possible resource.
35:24How can we begin to reclaim every last drop of what we let go to waste?
35:31Even in places that have a lot of water, like Finland.
35:39To me, Finland has always been the mysterious one of the Nordic countries.
35:44Their sense of humor is bone dry and very funny.
35:48And they have good reason to laugh.
35:51In fact, on the Global Happiness Index, Finland has been ranked the happiest place on Earth for eight years straight.
35:59That was a deer. I'm in Torko. Beautiful.
36:08Oh, hello.
36:09Hi.
36:10Would you like to go to sauna first to warm up?
36:13That's a good idea.
36:15If you want to understand the Finnish mindset, you have to do the most Finnish thing possible and take a sauna.
36:23So, when you hear something like happiest people in the world, does it make sense to you?
36:29Everybody seems to connect it to nature, one way or another.
36:33And that's, it's almost impossible to put into words.
36:37I mean, I know how it feels inside.
36:39Yeah.
36:40But to try to explain to somebody is difficult.
36:43So, what is it, what are you doing here? What is this?
36:45This is birch.
36:46Go for it.
36:47Birch. Oh.
36:48Give me that.
36:50Quiet!
36:51Ah!
36:52Ah!
36:53Ah!
36:54Ah!
36:55Ah!
36:56All right.
36:57I'm not going to lie.
36:58Yeah.
36:59It's not that bad.
37:00Holy!
37:01That's cold!
37:02I'm just letting it go.
37:03Ah!
37:04Yeah.
37:05Oh, my God.
37:06That's really cold.
37:07It is kind of cool.
37:08Mmm.
37:09This is so good.
37:13So, I wanted to make, like, just basic Finnish food.
37:17Mm-hmm.
37:18Kind of, it describes the simplicity.
37:21And we are simple people.
37:23Yeah, that's...
37:24Yeah.
37:25That's actually one way of putting it, yeah.
37:26That's probably one of the reason, like, Finland is called the happiest country in the world.
37:32We are not laughing and dancing on the streets.
37:35That's not it.
37:36We take what we have and we are happy with it.
37:41So, tell me something.
37:43There's a thing called every man's right.
37:45Right.
37:46What is that?
37:47Can you explain it to me?
37:48It means that all Finns or everybody in Finland has the right to wander around in the woods.
37:55You can pick up berries.
37:56You can pick up mushrooms.
37:58You can camp.
38:00How important is that in Finland?
38:04Do you feel unnatural?
38:07I think we really enjoy nature, but we also have to have the responsibility to take care of it.
38:15That is kind of part of us.
38:19And Finns don't just put that ethers into practice.
38:24They make it very personal.
38:27By taking a firm stance on reducing all waste, including everything that flows between the bathroom and the Baltic Sea.
38:34It's a beautiful city, Torko.
38:38And it's very impressive what they do with their poop.
38:41This is the Kakolanmeki sewage plant, one of the most advanced water treatment plants in the world.
38:54Hello.
38:55Hello.
38:56Hello.
38:57Welcome.
38:59Because this is a pretty advanced facility, have you had a lot of visitors from around the world to come?
39:05Yeah.
39:06Almost every week.
39:07We have several thousand visitors every year.
39:10Really?
39:11Yeah.
39:12So I'm not special for you?
39:15You're one of the thousands.
39:17Oh, thank you.
39:19This elevator is taking us down.
39:23Way down.
39:24Here you can see the whole cave.
39:29Was this a natural cave?
39:31Did you just use it?
39:32Did you dig this out?
39:33Everything is excavated for this process.
39:36Wow.
39:37All the waste comes to here.
39:39Yeah, everything.
39:40Per day, it's around 40 Olympic swimming pools of shit daily.
39:51Oh, yeah.
39:53Do you smell something?
39:54I smell something.
39:57Oh, fuck me.
39:59That is bad.
40:01This is the smell of raw suites.
40:05Yeah.
40:06Yeah.
40:07Makes you feel stronger.
40:08Yeah, it makes me feel something.
40:11Manly.
40:13Here we add ferrous sulfate to the water, and it helps the slots spin together, and then sink in the bottom.
40:22And mostly you find some disgusting stuff from the screening, but sometimes something fun.
40:28So we have a little collection here.
40:30This reminds me, do you remember the movie Pulp Fiction?
40:33Yeah.
40:34I carried this clock up my ass.
40:39Next, we will see the place where the actual magic happens in our resin process.
40:46Well, this is very...
40:47This is fresh smell.
40:48This is good.
40:49This is nice.
40:50It's full of little workers.
40:53Billions of microbes working for us, doing the purification.
40:57Is that why it seems like it's almost like it's bubbly?
41:00Yeah.
41:01These microbes, these are the ones that really do the hard work here.
41:04Yeah.
41:05Here we remove fosforus and nitrogen.
41:08Fosforus and nitrogen are one of the biggest pollutants in the Baltic Sea.
41:13So that's why this is so important.
41:17How long is this?
41:18100 meters.
41:20So as you can see, the water starts to be clearer now.
41:23So the process is basically, it gets, I mean, literally cleaner and cleaner and cleaner the further we go.
41:29Yeah.
41:30So it does, it looks quite clean.
41:32We have tested.
41:33Come here.
41:34And don't drop it.
41:35I won't drop it.
41:36Two meters.
41:37I can still see it.
41:38Two and a half meters.
41:40This is it.
41:41Two and 75 maybe.
41:42Yeah.
41:43Is that good?
41:44Very good.
41:45Usually when it's over two meters, it's acceptable.
41:47This is the UV plant.
41:48This is our newest process.
41:49UV, like in UV light.
41:50Yeah.
41:51There you can see some glow of the UV disinfection.
42:14And what does UV light, what does it do?
42:16Expose the pathogens to radiation so they can't reproduce or cause infections anymore.
42:24When the water goes out to the sea, it's clear, swimmable water.
42:29Do you have a place where we can swim?
42:31Not really.
42:32Ah.
42:33But we have a sauna.
42:35Yeah.
42:36But what is this obsession with saunas in Finland?
42:39I don't know.
42:41Usually it's cold, wet, dark.
42:45Sauna is the place where you can relax in warm.
42:48Maybe that's one of the reasons we are the happiest people.
42:51Oh yeah.
42:52You are the happiest people.
42:53Yeah.
42:54Sauna is a good reason to be happy.
42:57Once the water is purified, it's released back into the sea, finishing its journey.
43:03But what about the sludge that's been filtered out?
43:06Yeah.
43:07This is the shit dropping place.
43:10The sludge is separated to these tanks.
43:13Uh huh.
43:14Then it goes to centrifuges and takes the excess water out and drop the dried sludge to these brown silos.
43:23And then that's been picked up and taken where?
43:26Yeah.
43:27By these guys.
43:28The truck comes here five times a day, around 30 tons each truck, taking it to biogas station.
43:35They digest the sludge forming biogas.
43:38Then they liquefy the biogas for transport fuel.
43:42And the nitrients they recover to the agriculture and landscaping.
43:48This truck actually runs with biogas made out of shit.
43:53Wow.
43:54Yeah.
43:55So you want to load this?
43:56I can't wait to press the button.
43:59Yeah.
44:00And uh, just push this one.
44:02Okay.
44:03This is open.
44:04Okay.
44:05And just keep it.
44:06Keep it open?
44:07Yeah.
44:08Release the Kraken.
44:09Push and release.
44:10Oh my God.
44:12Oh that's, that's not what I expected.
44:15Oh yes.
44:18Oh.
44:19Such a happy feeling.
44:22The basic idea behind it, that we're using all resource.
44:27Yes.
44:28I think this is the right way.
44:29Yeah.
44:30Of course.
44:31And now you can close it.
44:33Okay.
44:34That's it.
44:35Yeah.
44:36And uh.
44:37I take the controller.
44:39Oh yeah.
44:41Transforming sludge into biofuel isn't the only way this system harvests energy from waste.
44:52The waste water that comes in here is actually very warm.
44:58In our facility, the heat in the water is recovered and used as a heating for around 20,000 inhabitants in Turku area.
45:09We produce over 10 times energy we use as the whole process.
45:14And also our climate impact is negative.
45:19In Turku, even waste water is reclaimed and treated as a valuable resource.
45:27As we wrap up the tour, it seems only natural that we end the day in the most Finnish way possible.
45:33How many times have you had a camera crew filming you when you were in a sauna?
45:40This is my first time, I guess.
45:42Yeah.
45:43Yeah.
45:44First time.
45:45If you want to go out and hunt a fish in Finland, you can do it.
45:48Everyone's right.
45:49Yeah.
45:50Yeah.
45:51Joni is our fisher guy.
45:53Yeah.
45:54That's why all this work here is so important for me.
45:58Because I love to fish.
45:59Yeah.
46:00So it's nice to go to the sea and see the clear water and nature.
46:04Yeah.
46:05So.
46:06Are you proud of this place?
46:07Of course.
46:08Really, really proud.
46:09We wouldn't let you in if we weren't proud of this.
46:12Okay.
46:13We love to tell what we do.
46:17This is great.
46:19What gives you the most joy in your work?
46:34The satisfaction of many communities accessing water which they otherwise would not have.
46:38In an atmosphere where the environment itself is upgraded and it becomes joyful.
46:46Plus, communities can be part of the solution.
46:55For me, that gives me hope.
46:57Like, because that shows how important community is for all of us.
47:01To feel connected, to feel part of something and to have a responsibility for each other.
47:07I think the world is cynical enough as it is.
47:09So optimism is the only way forward.
47:16Over the end.
47:18So hopeful.
47:19And I'm going to price something nice.
47:22After the end.
47:23And so hopeful.
47:25But like and then I understand.
47:26The future is going to be a cool thing, no more confidence,しゅいづつしゅいづつしゅいづつしゅいづつしゅいづつしゅいづつしゅいゥつしゅいづつしゅいづつしゅいゥつしゅいゥつしゅいづつしゅいづつゆつ…
47:31Oh character, I know.
47:32Order it or?
47:34That's it.
47:36Now it depends.
47:38You've got such a year.
47:39I know.
47:41Oh a year.
47:43Oh.
47:45You know.
