CHERRAPUNJI, India — Almost no place on Earth gets more rain than this small hill town. Nearly 40 feet falls every year — more than 12 times what Seattle gets. Storms often drop more than a foot a day. The monsoon is epic.

But during the dry season from November through March, many in this corner of India struggle to find water. Some are forced to walk long distances to fill jugs in springs or streams. Taps in Shillong, the capital of Meghalaya State, spout water for just a few hours a day. And when it arrives, the water is often not drinkable.

That people in one of the rainiest places on the planet struggle to get potable water is emblematic of the profound water challenges that India faces. Every year, about 600,000 Indian children die because of diarrhea or pneumonia, often caused by toxic water and poor hygiene, according to Unicef.

Half of the water supply in rural areas, where 70 percent of India’s population lives, is routinely contaminated with toxic bacteria. Employment in manufacturing in India has declined in recent years, and a prime reason may be the difficulty companies face getting water.
