In order to provide access to clean water and reduce distances to clean water sources, a Water Shop including a Trunz water treatment unit (TWM)  was opened within the framework of a charity project under the patronate of Walter Reist Holding Ltd. The Water Shop is located and integrated in the African School in Tanzania and is operated locally. Know-how transfer from Trunz to local operators was conducted via technical trainings Trunz held in Tansania.
