Quetta, a city in Pakistan with 1.5 million people, needs roughly 60 million gallons (227 million Liters) of water every day, but the Water and Sanitation Authority, the department responsible for the city's water supply, is only able to provide about half.

It is estimated that around 30,000 tube wells operate across the city — nearly half of them unregistered.

Unlike other regions of Pakistan, Quetta relies almost entirely on underground water. But the levels have dropped to alarming depths.

This is made worse by low rainfall.

Quetta is the capital of Balochistan, Pakistan's largest and most sparsely populated province. The region faces severe water shortages because of its geography and climate.
