We have some exciting news from Tanzania that we would like to share with you. Our devices TZ03, TZ04, TZ05 and TZ06 are now nine months old, so it is time for a water test to ensure that the quality of the output water is still good. Unfortunately, only TZ03 and TZ04 have been tested so far. The other devices were covered when the test was carried out. Please make sure to follow this blog, we will definitely post the other results as well.
The results from TZ03 and TZ04 look very promising! Both devices use input water which is heavily contaminated with E. coli bacteria. After the treatment, no bacteria were found in the devices’ output water. This result was validated by the laboratory MUWSA (Moshi Urban Water Supply And Sanitation Authority). It means, that water treated by both devices is safe for everyday use. We are motivated by those results as they show us one more time that the SoWaDi-concept of treating water works, even over longer periods of time. The exact test results are posted in the picture-gallery above. If you have any questions regarding the testing, do not hesitate to contact us using the contact-sheet… 😉
Besides the negative test results, all devices are in a good shape! Minor repair jobs like changing the containers’ tap or cover were done, but all in all the devices mastered the rainy season with no problems.
Right now, the devices’ output is relatively low (an overview of the output from TZ04 is displayed in the picture-gallery above). Hopefully, the weather will get a little better, so we can see an increase in output. Let’s keep the fingers crossed!
After now more than three months since the project meetings have been switched to a virtual way, a long awaited meeting took place again on Friday the 17.07. All SoWaDi members who had time and were in the mood spent a very nice evening on the area of the device. The meeting was decoupled from the actual project meetings and should mainly serve to strengthen the group.
Also present were Steffen and Alex, who together with Sara made our devicethe center of their ADP (Advanced Design Project). In the past semester they have been working intensively on the question of which long-term data are usefuland how to optimize the measurement technology. On Friday they shared their work progress and findings with the entire group. It was very interesting and the three have done a great job in the last months! A separate blog entry on the details of their work is already being planned.
The coming together was very nice. Until the evening hours we had a picnic together and talked about all kinds of things. However, despite all the joy of the reunion, we also always made sure to wear masks and keep a safe distance. Even though the situation in Germany allows for more face-to-face meetings, we decided to continue to work together virtually. So far the regular meetings have worked well that way and each group continues to work very hard on its self-chosen work packages.
While we hope to meet again soon in person, we recognize the urgency to avoid accumulations in order to protect ourselves and our loved ones as much as possible!
Stay healthy and look forward to an early update from the ADP team!
During the last weeks we have received news about our devices from Tanzania and so we take the opportunity to share this news with all interested parties in the following blog entry.
The Kilimanjaro Childlight Foundation travelled with a small group to Malage VTC and Kidia to visit the six facilities and exchange information with the users. It turned out that currently only three of the six built devices are in operation. Due to the COVID-19 pandemic and the resulting school closures, the facilities of Kidia Primary and Secondary School are still not in operation, but this is expected to change with schools opening soon.
In addition, the weather in Tanzania is still very cloudy , as the rainy season has only recently ended. Therefore, the planned extraction of water samples could not take place, because the devices unfortunately do not provide any output without sunshine. For the same reason another device is still covered, but this one will be active again as soon as the weather allows it.
At the Malage VTC the devices are running as planned, which makes us very happy!
We hope that all SoWaDi participants are doing well according to the circumstances and we are looking forward to further feedback from Tanzania as soon as the devices are up and running again.
