SUSTAINABLE TECHNOLOGIES
Water tank:
An idea that by addressing one issue, a chain effect might just start on going…
The system we plan on installing in the school includes a water tank for storing harvested rainwater during the rainy season in order to have water in the dry season. Now, this is where things start to get complicated in terms of materials, expertise and mostly- cost!
We looked at the obvious options out there for sealed drinking water tanks and tried to think how to make them make more sense in the village- plastic and cement. We didn’t really like both ideas for several reason. For most, those solutions aren’t sustainable for the village life, they don’t provide the opportunity to produce more items and have more people benefit off the technique.
So, we tried thinking what are the resources available in MK, what the people there use as building materials.
That would be EARTH!
Turns out that quite a few water tanks around the world were made out of earth and some of them out of compressed earth blocks. These blocks could be stabilized with a small amount of cement or lime to produce durable, sealed blocks which then would be plastered in order to hold water.  Having the knowledge and machinery (a simple mechanic hand press) in the village could allow families to make their own rainwater harvesting systems and also use the blocks as building material for building homes.
Little Big Africa, an Ugandan NGO has been building water tanks out of compressed earth blocks for a few years, take a look at their video:

You could also read about the process on the file attached that was written by UNITED NATIONS CENTRE FOR HUMAN SETTLEMENTS (UNCHS – HABITAT) and AUROVILLECOMPRESSED EARTH BLOCKS (CEB) UNhabitat BUILDING CENTRE.
We are still looking into this idea and hope to be able to make it work, we would love to hear from people that have experience in the area so if you know someone… please contact us!

 

 

 

ETHIOPIA

EWB – Technion Ethiopia group is active in Meskele Kristos (MK), a small village in Amahara region, about 4 hour drive from Lalibella.

After visiting the village and returning with lots of info and data to process, we  decided that our main objective will be to supply water for the school that’s in the village in order to reduce hygiene and other health problems. currently, there are no running water in the school and no access to near by water source, which leaves more then 300 children without water. this means they can’t wash their face to freshen up, they don’t have water to drink if they are thirsty (unless they carry a heavy water jerrycan all the way to the school) and of course they can’t wash their hands if it’s dirty.

So how are we going to do it?

What else did we have in mind?

Who are we working with and… How can YOU help?
