Final Report

Dear supporters,

The field activities of our project have come to an end. Just to give you a few numbers:

1114 school kids and 60 teachers were trained on simple methods to improve water, sanitation and hygiene conditions at schools and at home

- 72 water filters were installed at schools

- 150 families were provided with an innovative water treatment device and provided feedback for its further development

Moreover, the numerous activities carried out by our staff led to substantial changes in the way people think, feel and act in relation to water, sanitation and hygiene:

- At the end of the project, 89% of the children had safe drinking water available at school class at the moment of the evaluation – this number was at 1% when the project started.

- 58% of school kids correctly washed their hands with soap (up from 23% at the project start).

- 59% of the schools had adequate and clean sanitary installations available at the end of the project, up from 4% at project start.

These numbers clearly show that the project has created a massive improvement in water, sanitation and hygiene conditions at the local schools. It also is clear that the results can be further improved, and that’s why we will continue to support these schools with technical advice and supply of materials (e.g., candles for the ceramic filters).

Now that the activities in the field have stopped is the moment when we start with the second phase of the project, which is at least as important as the first phase: We are documenting our experiences in order to share them with other people and organizations. In this case, our most important conversation partner is the Ministry of Education. Before and throughout the project we informed people at local and at district level about the project, and we now are in conversations on how to integrate some of the modules we implemented into the curricula of the Ministry and how we can improve in general the water, sanitation and hygiene conditions at schools, as these have a significant impact on absenteesm and on learning results.

We will keep working on the improvement on water-related issues at schools in Bolivia. If you want to continue supporting our work at schools, please check out our other projects on GlobalGiving.

For us, this project has been a very positive experience. We have implemented an innovative methodology and helped improving basic services at schools. We think this is a model which deserves further attention and will be working with our local partners to support additional schools in Bolivia and in the region.

At this point, we also would like to thank all our supporters and sponsors – without you, the project would not have come as far as it did.

Thankfully,

Matthias Saladin

Final Report

This SODIS indicator goes from red to yellow in 6h
This SODIS indicator goes from red to yellow in 6h

Dear supporters,

This is the final report on our project to develop an indicator for Solar Water Disinfection (SODIS). The goal of this project was to develp and test a low-cost device which can tell users of the SODIS method when the PET bottles which are used for this process have been exposed to sufficient amounts of sunlight. During the course of the project, we tried several approaches to solve this problem:

- Materials-based approach: Some materials change colour according to the amount of sunlight they receive. This fact can be use to produce a SODIS indicator, and in fact we identified a producer of an adequate product and carried out field tests with it. It works well in the field, but the drawbacks are the fact that the indicators can only be used once and that the price per unit is fairly high - 0.40$ may sound like a small amount, but each user family will need at least 10 to start with, and that's already 4$ - and then they will need more... However, the product works and the SODIS Foundation will continue to use it where it sees a need and a benefit in doing so - for example in situations where there is not enough time to train people thoroughly, like it is the case in some emergency siutations we are attending at the moment in Bolivia.

- Electronic approach. We have supported and collaborated with several groups (both research and private sector) around the world who are working on the development of an electronic device which measures the amount of sunshine received and tells a user when the water in the bottles is ready for drinking. Two of these groups went ahead to set up formal organizations (www.helioz.org and www.potavida.org, who we mentioned earlier) and are currently undergoing field tests of advanced versions of their prototypes. The advantage of these devices, as compared to a single-use device, is that they can be used for a long time (several years), which makes for an ideal training and teaching device. The drawback is the prize - but this will come down as the numbers of units produced increase. We will keep in contact with these organizations and actually may field-tests some of their products later this year. 

Thus, we think that we have reached a stage where we can close this project. Over the past years, we have developed and tested several prototypes, supported research around the world and helped to establish two companies. We hope that this initiative will continue evolving and wish all the people and organizations involved all the best - for that in the near future, a SODIS indicator will be available for everyone who needs one - potentially, that would be at least 870 million people who currently do not have access to safe drinking water!

If you have questions or comments about our project, please do not hesitate to contact us (info@fundacionsodis.org).

At this point, we also want to thank all of the people who supported this project. Without these inputs, we could not have done all of this, and we also want to extend the thanks of all the people who directly benefited from this project.

Best regareds from the whole project team,

Matthias Saladin

Field evaluation

Interviews with beneficiary families
Interviews with beneficiary families

For the second half of November, our field staff has been busy with the evaluation of the project in Anzaldo. They interviewed dozens of children and adults, they organized group discussions, but also carried out in-depth conversations with authorities at schools and at the municipality in order to collect data on the outcomes and results of this project. In the next few weeks, we will work on the final report, which we then also will share with institutional partners and other organizations working in the sectors of education, water/sanitation, and health.

As you may remember, this project is part of a larger disaster risk-reduction program of the municipality. Therefore, several organizations working in the field of emergency aid and risk reduction are very much interested to learn more about the project, the results and the lessons learned. We will present the final report at the working group for disaster relief in Bolivia in 2014, and you will be able to download it from our website as well.

Most of our field activities have concluded by now. However, we will maintain contact with schools and the municipality in order to make sure the healthy habits learned throughout 2013 will continue in the new year, creating lasting benefits for children and their families. If we continue to receive donations for this project in the next few weeks, we will use the funds to spread the lessons learned to additional organizations – and we are considering the option of shooting a video – so please stay tuned.

In the meantime, we wish you a happy Christmas season, End-Of-the-Year, or whatever reasons there are to celebrate.

Best regards,

The whole project team at the SODIS Foundation
