Singapore's NEWater

It is a little known fact that Singapore has had a long battle in delivering sufficient water to its citizens. Using state of the art technology, the country is deeply committed to achieving its goal of an independent water supply. One such innovation is NEWater, which uses wastewater from homes and factories and is transformed into water pure enough to drink. It already accounts for 30% of the water used and there are hopes that by 2060, this figure will rise to 55%. In this episode of Asia Insight, we follow Singapore's efforts to save precious water and secure an independent domestic water supply.
