Fog Collectors NRP 3.0

The revolution in fog water collection

 

After years of experimentation and improvement, our NRP 3.0 fog collectors are currently the most technically advanced and productive in the world in the last 50 years in this sector, with a maximum collection of 1,074 liters / day and a life of more than 10 years.
 
The NRP 3.0 fog collector, have a huge collecting surface of 56 m2 into minimum space, only 1.6 m2, thus reducing the area occupied by 90% and minimizing the visual impact.
 
Its three-dimensional structure gives great stability and prevents the loss of water out of the structure and also minimizes the influence of the wind direction in production of water.
 
It also has a base designed to decant and filter the water before it passes to the tube system.
The materials used give the NRP 3.0 high strength, low weight and high durability.
 
Due to the rate cost-production, this system allows us to consider definitely the mists as another water resource, complementary to the existing resources, and this,  in a practical, cost-effective, sustainable and innovative.
 
Water from the mist can be used for qualitative and quantitative improvement of the waters from another origin, which can also help  to reduce transportation costs, pumping or treatment of these, saving energy and minimizing pollution.


Design Bases

Development of fog collectors NRP 3.0

As we have been working  for some years in a scientific and in a  professional way with the flat collectors or Chilean type, we realiced its complications and shortcomings. For this reason, in 2008 we began to design some collectors based on the following design bases:
 
A fog collector very stable against wind and with no need of tensioners, which occupies little space, easy to transport and to install, it does not need constant maintenance, it avoids constant loosing of water, (collected by the meshes) outside the structure, and therefore, the loss of production, which will increase the rate of precipitation of drops already captured, not been influenced by changes in the direction of the mist , so therefore, is is able to get more than 100 liters per day.
 
With all these data, we design our NRP 3.0 fog collectors in different models depending on their size, whose name refers to plants of the Canarian forest: Erica, Pinea and Garoé.

What is fog water collection?

 
The fog, produced normaly by low clouds impacting against a rugged terrain, can be captured by special mesh placed pn a support structure. These meshes retain the tiny water drops floating in the air, imitating the process  made ​​by the treetops and giving the name to the phenomenon known as "horizontal precipitation".
 
This technique is studied for over 50 years in many parts of the world and allows the use of this water resource.
 
It was in Chile, particularly in the Atacama Desert, where it began to research and develop collection instruments primarily between the years 1960-1980, with the help of distinguished researchers from the Catholic University of the North.
 
This is how the Chilean type "catchers" appeard, which have been used up to now. Although cheap and easy, these fog collectors have certain drawbacks such as low production, occupied area, water leaks out of the structure, stability problems and breakage.
 
In order to solve these problems, we have designed the NRP 3.0 fog collectors, which represent the most advanced technology and higher production worldwide today.

 

The Garoé

The holy tree of the island of El Hierro

In pre-Hispanic times, the inhabitants of the island of El Hierro, the "Bimbaches", worshiped a tree that mysteriously flowded water. On an island where the water was such a limited resource that people died of thirst, it is easy to imagine the  importance  that  this tree had for them.
 
The legend says that  the Island could only be conquered when a "Bimbache" Princess, falled in love with a conqueror,  revealed the location of the holy tree, and then the Island was conquered by the Spanish.
 
Now we know that the Garoé tree (a Til tree), due to its location at the head of a ravine in the town of San Andrés, captures  with its branches and leaves water from the fog.
 
Today it can be visited this unique place which preserves the holes dug at the foot of the tree filled with water, which supplied the bimbaches.
