DCA: freshwater factory

parisian firm design crew for architecture (DCA) created ‘freshwater factory’, a proposal for the 2010 skyscraper competition.

as they were looking for the redefinition of the term ‘skyscraper’ through the use of new programs, we decided to look for somewhere else to implement a skyscraper. obviously, it has to be the countryside. the main question we had to answer then was: why would we build a skyscraper in the countryside? what issue could justify the need to build skyscrapers in the countryside?

although water is very present on earth, 97% is salted and 2% is blocked as ice.  there is only about 1% left of liquid freshwater and the UNO and the world water council estimate there might be a crisis affecting half the worldwide population by 2030. freshwater will be a major stake in the 21st century. Indeed the production of a daily food intake for a human being requires 3000 liters of freshwater and the annual rate of freshwater needs is 64 billions cubic meters.

farming makes up 70% of the worldwide freshwater consumption. our proposal is a totally new building: an unseen response to sustainable development and the up coming stakes.

the tower is made of several circular tanks filled with brackish water. these tanks are sheltered in spherical greenhouses. the brackish water is brought up in the tower by tidal powered pumps. the water pipes network is incorporated in the tower main structure. the tanks are planted with mangroves: these plants have the particularity to grow on brackish water and to sweat freshwater. so, the mangroves feed on brackish water and then their leaves perspire freshwater. this freshwater sweat evaporates in the greenhouse and condensates by the night into dew on the sphere plastic wall to be collected in a freshwater tank. then, thanks to its at altitude storage, the produced freshwater can be distributed to the fields by gravitational flow. the total surface of the tower is one hectare. one hectare of cultivated mangroves should produce 30000 liters of freshwater a day. for example, the tower will be able to irrigate a one-hectare field of tomato a day.

almeria is a province located on the south of spain, along the mediterranean coast. this is the place where most of european fruits and vegetables are cultivated. any kind of fruits or vegetables can grow there at any time of the year. sun does shine more than 2965 hours a year. greenhouses fill more than 90% of the ground: that is why this area is nicknamed ‘the plastic sea’. greenhouses spread over the landscape, undulating over the course of the hills.

this is in this sunny and arid climate that their project is to be built. the tower is designed to produce freshwater to irrigate the cultivated lands standing at its feet. they implemented their proposal in almeria as a case study however the project can apply anywhere.

this project is a new solution for farming’s needs: s skyscraper which is a freshwater factory.

  • very ugly

    nko says:
  • would make a whole lot more sense to just store the water in the vertical mass, rather than having to engineer having all those trees in the air- would be much more efficient – but then of course it undermines the made-up justification for a “skyscraper in the countryside” – oops.

  • Beautiful !

    Reginus says:
  • Vormgeving prachtig, uiteraard weer veel te ambitieus.
    Het principe is Allang bekend in de veel goedkopere uitvoeringen.

    ruudvanthul says:
  • cool

  • bravo

    LIJNJ says:
  • planetas en miniatura.?

  • an alien spreading its seeds ugly

    hala says:
  • i like it!

    mal says:
  • I love the organic look of the building! Awesomely beautiful!

    Paul says:
  • simply amazing!

    Justina says:
  • Amazing… I´m impressed

    kento says:
  • how much precious energy is spent for the construction?

    energix says:
  • It is a very smart idea. But considering the amount of virgin land in our planet, I wouldnt like to see just another skyscraper at the coastline.
