Visitors sampling "Asia's most expensive water", priced at $1,260 a bottle, at a pop-up bar in Ocean Financial Centre. The campaign was launched by non-profit group Lien Aid yesterday to raise awareness that clean water is a luxury for many poor people in Asia. "We wanted to highlight the fact that the rural poor are paying more for clean water while earning just a tiny fraction of what we do here in Singapore," said Lien Aid CEO Koh Lian Hock.
