Since graduating from university, Lim Chong Tee (pictured left) and his co-founders David Pong (pictured right) and Vincent Loka (pictured centre) have tirelessly dedicated themselves to solving the problem of access to clean water through their social enterprise, Wateroam. They currently provide a simple water filtration system with a reach that extends to 30 countries, including Malaysia, Indonesia and Cambodia. They have created a series of ROAMfilters in different sizes along for various amounts of water to be purified within a minute, all in an easy-to-carry foldable membrane bag. Wateroam has won several awards for its efforts, including Best Innovation for the “Early-Stage” category in the 2016 ASEAN Impact Challenge and the 2015 Shell LiveWIRE Awards. It has since brought clean water to more than 30,000 people in 14 countries across Southeast Asia, as of April 2018, and hopes to help 30 million people in the region within the next five years.
