Water innovation may help solve the world’s water crisis: now, how to standardize and distribute Askwar Hilonga’s invention? Image: furman.edu.
World water is in crisis. For example, 70% of Tanzanian households lack clean drinking water: now Askwar Hilonga, of the Nelson Mandela African Institute of Science and Technology, is about to change that. Growing up in rural Tanzania, the chemical engineer recalls family and friends suffering from water-borne illnesses, motivating an innovation combining one of the world’s oldest filters, sand, with one of the newest: nanotechnology. The Roman aqueducts were similarly resultant of a combination of both new and traditional technologies. Askwar Hilonga’s success may soon benefit the rest of the world: 1 in 9 people lack clean drinking water, globally. How can new technologies, supported by industry, governance and global agreements, improve water for the world?
