The world is running out of clean water, not because it is disappearing, but because of how inefficiently we manage it. According to the United Nations, more than 2.2 billion people lack access to safe drinking water, and nearly half of the global population experiences severe water scarcity for at least one month each year.
By 2030, the OECD projects a 40% shortfall in the world’s available freshwater supply if current consumption and pollution trends continue.
Climate change is compounding the issue.
Droughts, floods, and erratic rainfall are disrupting water systems in every region. The World Bank estimates that water scarcity could cost some nations up to 6% of their GDP by the end of the decade.
Meanwhile, aging infrastructure leads to an estimated 32 billion cubic meters of water lost annually through leaks.
In response, a new generation of WaterTech startups is tackling the global water crisis through technology, data, and circular design.
These companies are building scalable systems for leak detection, wastewater reuse, desalination, atmospheric water generation, and precision irrigation — turning one of humanity’s oldest challenges into an innovation frontier.
Here are some WaterTech startups proving that technology and purpose can work together to secure the planet’s most vital resource for generations to come.
