GTO Summer Party at Müggelsee

Together with family and friends of the GTO we had a nice summer party on August 11th!

Equipped with a safety helmet, we started a museum tour at Lake Müggelsee in the Old Waterworks. At the beginning we got an insight into the history of the waterworks, how the waste water systems of Berlin developed and which problems the people had to face concerning sanitary facilities and water supply at that time. Through the machine hall, the cellar with its steep stairs and low ceilings and the seawater pumping station we continued to explore the old waterworks. After the technical input it was time for us to enjoy the nice weather and a big picnic at the lake!

Day of Action on 4 June: SDG 6 - Water and Sanitation for all!

*English subtitles are available in the video setup*

According to the World Health Organization (WHO), 60% of the world population lives without secure sanitation, which protects health and the environment. In line with the World Environment Day on 5 June and as a contribution to the European Sustainability Week, more than 75 Berlin pupils organised an “Actions-March” in Berlin’s governmental district and demanded a “Toiletised World”.


The Parliamentary State Secretary Dr. Maria Flachsbarth from the Federal Ministry for Economic Cooperation and Development (BMZ) appreciated the pupils’ efforts publicly– especially, because it is such a taboo issue.


Thanks to everyone who supported this event and contributed to its great success!


The event was initiated by pupils from the Anna-Essinger-Gemeinschaftsschule, the Gemein-schaftsschule on Campus Rütli and the Georg-von-Giesche-Schule, together with the GTO. The project is financially supported by the Federal Ministry for Economic Cooperation and Development (BMZ), by the state office for developmental cooperation Berlin and Brot für die Welt. We also thank the supplier of washroom products, CWS-boco, who is a long-term supporter of projects of the GTO.

Training on hygiene

Hygiene and its immense importance in everyday life were the focus of our basic seminar "Hygiene education in development cooperation and humanitarian emergency relief", which took place on 26 and 27 January in Berlin. The participants from all over Germany learned, among others, different approaches to hygiene education and behavior change and got an insight into the most effective hygiene practices. By the way, hand washing with soap is the best and cheapest health care. Special thanks go to Ina Jurga from WASH United for her speaker contribution as well as the participants for many exciting inputs.

The ABC seminar series was sponsored by ENGAGEMENT GLOBAL on behalf of the BMZ.

Sustainable Sanitation in Focus

What is the Latin word for shit? What do you have to consider when building a toilet and how can you use urine as a fertilizer? These and many more questions were the subject of our basic seminar "Sustainable Sanitation in Development Cooperation" on January 12. and 13. in Berlin. In addition to a lot of theoretical input, we became creative and made a urine diversion dehydration toilet (UDDT) and a so-called tree toilet or "Arborloo" out of pizza boxes etc.

The seminar was funded by ENGAGEMENT GLOBAL on behalf of BMZ.

International Day of Persons with Disabilities

On the occasion of this day, celebrated annually worldwide on December 3, 11th grade students of Berlin’s Kaethe-Kollwitz-School performed a flashmob and a “reverse-demonstration” on November 29, 2017.  


One student began proclaiming “Toilets save lives” in sign language, with each repetition he was joined by others. Afterwards the group moved backwards in front of Brandenburg Gate to draw attention to the fact that not enough progress is being made concerning the issue of inclusive sanitation.

“Access to school toilets is particularly key to bringing and keeping girls with disabilities in school”, said Toyin Aderemi-Ige, Head of Christoffel Blindenmission (CBM) in Nigeria, who participated at the demonstration.  


Many thanks to everyone who supported our event, especially the students and its teachers, yomma, Christoffel-Blindenmission Deutschland e.V. and SOZIALHELDEN e.V.

Day of Action on the occasion of the World Water Day

On March 30, 2017 the GTO and around 100 Berlin pupils carried out an action da in the hall WASsERLEBEN at the trade fair Wasser Berlin International. 

With huge world maps depicting the water scarcity, self-printed t-shirts and a wheel of fortune, the young people wanted to show how important clean drinking water and toilets are for a healthy life.

In a handwash competition by means of a WASHaLOT - a group handwashing system of the Gesellschaft für Internationale Zusammenarbeit GIZ - it was demonstrated how kids can clean their hands with 100 milliliters of water and thus prevent fatal diseases.


We would like to thanks all persons involved.


The action is part of the "Klobalisierte Welt" project, which is made possible through means of Engagement Global on behalf of the Federal Ministry for Economic Cooperation and Development and by the Landesstelle für Entwicklungszusammenarbeit des Landes Berlin. We also thank CWS-boco ( for the long-term support.
