Water Systems in Cities of the Future | Jörg Drewes
Everyone of us consumes 140 Liters of water each day, but only a fraction of it is used for cooking and drinking. Moreover, the water systems we rely upon are based on technology that is far too old and not future-proof. Professor Jörg Drewes works on alternative models for the water systems of the future. He encourages us to use the term 'used water' instead of 'wastewater', and makes the case for its sustainable treatment to ensure proper water supply for an ever growing urban population.
