In this Tuesday, July 16, 2019, photo, people fill drinking water from a private water supplier tanker on the outskirts of Chennai, capital of the southern Indian state of Tamil Nadu. In Chennai, a coastal city of about 10 million and the capital of Tamil Nadu state, rapid development and rampant construction have overtaxed a once-abundant natural water supply, forcing the government to spend huge sums to desalinate sea water, bring water by train from hundreds of kilometers (miles) away and deploy an army of water trucks to people whose household taps have suddenly run dry.
