The power of coloured dots

Dear supporters,

We wanted to let you know about the exciting latest developments at our project. As you may know, we want to develop a device which tells users of the SODIS method (Solar Water Disinfection) when a bottle has been exposed to sufficient amounts of sunshine and the water is safe for drinking. We have been working with several companies and research groups around the world, and so far we have focused on electronic devices. However, we are now also using a second approach, which is based on colour-changing materials. These can be delivered in the form of stickers to the users, taking up very little space and for a fraction of the cost of an electronic device.

In May and June, we have been in contact with a group of scientist at Queens University in Belfast (Northern Ireland), and they have advanced significantly in the develpment of a prototype. Basically, they exposed different colour-changing materials to strong sunlight and measured how quickly colour changes. The results look like a bunch of coloured dots, but based on these results they can develop an advanced prototype, which we then will test in the field. Ideally, we want to have a material which is re-usable for many times, but this is a major technological challenge (the materials need to "recover" overnithg). Thus, for the moment we will work with disposable materials, but also keep derveloping the re-usable ones - they will be more cost-effective, save limited resources and produce less waste.

Please let us know if this report has been interesting and useful for you. If so, please share this message with someone who might be interested in this project and in supporting our cause of improving drinking water quality of marginalized people in Latin America. Obviously, we are still several months away from a finished product which may benefit millions of people. In the meantime, if you want to support a project with immediate impact on improving drinking water quality, have a look at our micro-project for 18 day care centers in Cochabamba (see link below).

Best regards from the whole project team,

Matthias Saladin

PS: Just to avoid misinterpretations, we would like to clarify the the work of Queens University is directly funded by institutional donors, not by the SODIS Foundation. Our support focused on establishing links between different research groups and to identify an ideal place for field testing. The funds we receive through Global Giving are used for our own tests and for coordination activities.

Update from the field

Dear supporters,

During our recent visit to the field, we confirmed what the locally based team members told us before: that the project is progressing well, and that the impact is ever more visible. Whereas the project in the first year focussed on teaching kids and educational staff the importance of safe drinking water and how to obtain it, this year we want to get these messages to the whole community. As a starting point, we trained kids how to measure the quality of the locally available water - seeing that they actually were drinking water of non-potable quality got many people interested in our project and started to kick-start activities.

Just to mention a few of the activities carried out in 2013:

  • 510 primary teachers were trained on water and hygiene (update from last year's trainings)
  • 119 secondary teachers received training on safe drinking water and improved hygiene
  • 39 Water Committees were formed
  • 62 Safe Water Stations were installed at classrooms

As you can see, we have been busy, and we are now starting the activities to involve the whole community...

On a different note, wewanted to let you know that June 12 is a Bonus Day. This means that all donations received that day will be topped up by another 50%. Starting at 9:00 am EDT, GlobalGiving will match donations of up to $1,000 made through www.globalgiving.org. For example, if you make a donation of $50, actually $75 will go to the project. So please take advantage of this great opportunity and make a donation to one of our projects - every donation makes a difference.

Best regards from the whole project team

Dear supporters,

During my recent visit to the project in Bolivia, I confirmed what the local team had told me before: that the project is progressing well, and that the impact is ever more visible. Thanks to the great work done in the past few months, we immediately could start with the training activities, and the participation of the local population was overwhelming - the room where we started out training soon was so crowded that we had to move to a larger facility.

The project is starting to stirr up interest with the local people and authorities. The project is getting logistical support from the Municipality of Anzaldo, where the project is located. During out training sessions, we train people on how to obtain safe drinking water using two different methods:

  • Ceramic filters. These devices are very effective and can treat large amounts of water in a short time.
  • SODIS (Solar Water Disinfection): This method is very attractive because of its simplicity and its low costs.During the present project, we actually want people to use two different devices for SODIS: standard PET bottles (common soft drink bottles) and specially designed plastic bags.

Over the next few months, we want to collect data on the different methods and devices people are using in order to improve the products and to learn more about how such effective interventions can best be integrated into local traditions and habits.

On a different note, we wanted to let you know that June 12 is a Bonus Day. This means that all donations received that day will be topped up by another 50%. Starting at 9:00 am EDT, GlobalGiving will match donations of up to $1,000 made through www.globalgiving.org. For example, if you make a donation of $50, actually $75 will go to the project. So please take advantage of this great opportunity and make a donation to our project - every donation makes a difference.

Best regards from the whole project team
