Water scarcity can sink a city, says expert Tanvi Nagpal

Who ends up paying for all the waste and losses from old, leaky water systems? Ordinary families. For the most part, they have no choice but to foot higher and higher bills just to keep access to the water they need to live.

However, failure to invest in water systems and keep costs low for consumers can lead to huge consequences, according to Tanvi Nagpal, water policy expert and consultant for Tetra Tech. For example, Jakarta's failure to keep its water system up with its population growth led people to dig wells to provide themselves with the needed water. The result? One of the largest cities in the world and an economic engine of southeast Asia is physically sinking into the ground.

"We must think through an approach where we believe that everybody should get water, not just because we deserve water, but because it's important for all of society that everybody get this access to clean water," she said at a GZERO Live event organized by the Sustainability Leaders Council, a partnership between Eurasia Group, GZERO Media, and Suntory.
