"Trinkbares Wasser für alle" in the BILD newspaperWir waren in der Zeitung! Strictly speaking, in the BILD. We quote:

Together with prominent supporters, including tenor Rolandi Villazon, Gerhard Bartschat gives many people access to drinkable water. His Christmas campaign is currently on the run: With every T-shirt purchased for 29.90 euros, buyers donate 19.00 euros. The shirts can be purchased on www.trinkbares-wasser-für-alle.de or twfa.de The money is used for a gravity water filtration system that helps save lives. Each of these extremely easy-to-use filter systems can supply drinking water to at least 100 people a day. It turns water from rivers into drinkable water, making it a chance of survival for many.
