Die Gäste eines Cafés in der äthiopischen Stadt Shewarobit kommen nicht nur wegen des guten Essens und Trinkens, sondern auch aufgrund eines Luxus, den sie zu Hause nicht haben – nämlich Toiletten. Praktisch niemand in der Stadt besitzt eine solche. Die Exkremente der Café-Toiletten werden in unterirdischen Tanks gesammelt. Mit dem daraus entstehenden Biogas wird der Küchenherd betrieben. Dieses innovative Konzept einer Sanitär- und Energieversorgung entspricht der Botschaft des diesjährigen UN-Weltwassertags am 22. März: Von Abwässern gehen nicht nur Gefahren für die Gesundheit aus – sie können auch eine wertvolle Ressource sein.
