“By cutting the amount of lost water in half, 150 million people could be supplied with treated water”, said ADB’s Vice President for Knowledge Management and Sustainable Development Bindu Lohani.
ADB estimates that 29 billion cubic meters of water is lost each year in the region, causing Asia’s water utilities to lose more than US$ 9 billion in revenue each year.
The ADB study, which showcases eight of the best-performing water utilities  in Asia, shows that current unaccounted for water (UFW) levels in the region of up to 60%, can be brought down to less than 20%. Phnom Penh even managed to lower its UFW level to just 6% in 2008.
The study developed a Good Practices Success Framework (see figure above) with seven key elements that urban water utilities need to address. Regarding one of these elements, empowering the poor, the study notes that each of the eight water agencies studied provided some kind of subsidy for obtaining a water connection and, in deserving cases, for the use of water as well.
