Problem: What problem is this initiative trying to address?

The necessity for clean water is a well-known problem in 3rd world countries. In Manyara region, this problem is far more severe. The lack of infrastructures to collect surface water, combined with the fluoride contamination in groundwater, makes this basic requirement impossible to reach. The measured fluoride concentration there is 10 times higher than the max limit of WHO’s standard. When consuming such large amounts of fluoride, the mineral connects to the teeth and bones and creates irreversible damage.

Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?

Our goal is to achieve accessible water which is fluoride-free, a complicated mission when trying to divide the mineral from the water. As a solution, we have designed systems to harvest, collect and restore rainwater, when it rains heavily during the short wet season. After 4 years of working in this region, we understand the importance of the community’s involvement in this project. The strong bond that has been formed with the community is the main reason for the successful operation of the systems. We maintain a strong partnership with the leadership of the community, which encourages all to keep working together for the improvement of the existing systems and to think of new solutions for the challenges, which haven’t yet been solved yet. In addition to the water project, last year we’ve built a PV electricity system in the village’s health center. This what makes our NGO so special: We use our engineering knowledge Combined with a community aspect to meet the community’s needs.

Impact: What is the impact of the work to date? Specify both the social and the environmental impact of your work

During our work, we already installed 2 water harvesting systems that make a big change for the high school students. Before the systems were implemented the kids didn't have access to water from sunrise to sunset. Now they can drink clean water throughout the wet season and for another 2 months into the dry season. 900 youngsters study in this school. Building the harvesting systems is only the first step for us. We worked hard to create a local leading team inside the school that will maintain the existing systems. We will also train them to build new systems - if we'll have the funds for it. We invested a lot in lessons about the need for clean water and how to encourage the locals to act for achieving the desired goal. In addition, the EC solar system we implemented in the health center now enables doctors to treat patients during night time and also have refrigerated medicines (wider range!). The impact of this system is huge - It's the only clinic in a 10,000 people area!

Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?

In the past few years, our funds were mostly based on grants and donations from various sources: The first one Tel Aviv University that appreciates our initiative spirit and tries to support its ambitious students. Moreover, each and every year we address corporate and local companies that have or might have interests in Africa and can be interested in our cause as a way of giving back to the local community. In addition, a small part of our donation based on crowdfunding. Over the past year, we have been working on strengthening the connections with the Israeli embassy and government agencies in Tanzania, in order to secure out budgets on the long term and get an Increase local involvement in our projects.

Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?

EWB-TLV was established together with students from a variety of programs, In order to create a productive engineering work. The students in the project coming from engineering and education background, due to the understanding that in order to provide the best and most sustainable solution, culturally sensitive must be preserved. This is our added value. The ability to combine the worlds of engineering and education and to overcome the cultural gaps between Israel and Africa, in full synergy.

Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.

It all started in 2007 when an Israeli traveler in Tanzania came across the village, and while hiking there he noticed that children were suffering from various development problems and bodily deformations especially in the legs, lips and dental problems at a rate that seems unusual. This distinguish made him search for the source of the problem and after examining the area, he identified that the problem was the drinking water, but he didn't quite know what was the cause. When he returned to Israel he referred the problem to the branch of EAB at Tel Aviv University, and this is how our story with Tanzania began.

We have been working on the same idea since last 15 years and we have improved number of things as you can find from my entry. If you are interested in fluoride filter, we have developed that also at very low cost. It will help in meeting the water requirement and ground water also can be used, if water table is high.
