We all need water to survive—but access to the liquid lifeline isn’t always a given. With a shifting climate and ever-increasing agricultural and industrial demands on this limited commodity, UNICEF predicts that by 2025, half of the world’s population could be living in areas facing water scarcity. On top of the obvious resource drains, many countries are losing surprising amounts of potable water to leaks. For example, in the United States alone, an estimated 6 billion gallons of treated drinking water seep out of its supply every day due to aging pipelines and undetected leaks.

“Smart” water innovations may offer conservation solutions, though. As part of an overall smart city scheme, where internet of things (IoT) devices work hand-in-hand with AI to improve daily life, many municipalities are giving their water systems a makeover. From new meters to irrigation and pipeline maintenance, we look at some of the key intelligent technologies that endeavor to improve how we harness our water supply.
