WORLD WATER DAY 2022: Groundwater - making the invisible visible

Every year, the World Water Day highlights a specific aspect of freshwater. World Water Day 2022 draws attention to groundwater, the hidden water resource that has always been critically important but not fully recognized in sustainable development policy-making. The overarching message of the 2022 campaign is that exploring, protecting and sustainably using groundwater is central to surviving and adapting to climate change and meeting the needs of a growing population.

Out of sight, under our feet, groundwater is a hidden treasure that enriches our lives. 

Almost all of the liquid freshwater in the world is groundwater.

As climate change gets worse, groundwater will become more and more critical. 

We need to work together to sustainably manage this precious resource.

Groundwater may be out of sight, but it must not be out of mind. 


Join the World Water Day 2022 campaign and promote these key messages!

  • Groundwater is invisible, but its impact is visible everywhere.
  • Almost all of the liquid freshwater in the world is groundwater, supporting drinking water supplies, sanitation systems, farming, industry and ecosystems.
  • What we do on the surface matters underground. We must only put harmless, biodegradable products on the soil and use water as efficiently as possible.
  • Groundwater crosses borders. We must work together to manage transboundary groundwater resources.
  • We cannot manage what we do not measure. Groundwater must be thoroughly explored, analyzed and monitored.
  • Groundwater will play a critical role in adapting to climate change. We must protect and explore groundwater, balancing the needs of people and the planet.
