EarthFrom groundwater depletion to global sanitation gaps, these 20 facts reveal the scale of the world’s water crisis and why solving it starts with better measurement.

(April 22, 2026) — Water scarcity is happening now, and the numbers are staggering. Around one in four people globally lack access to safely managed drinking water. Groundwater reserves that took millennia to fill are being depleted faster than they can be replenished.

At Seametrics, we build the flow meters that help agricultural, industrial and municipal operators understand exactly how much water they’re using and how to do it responsibly. Measurement is how we can turn data into decisions and make every drop count.

  1. Around one in four people globally lack access to safely managed drinking water. This means their drinking water is not reliably safe, available at home, or free from contamination. Source
  2. Billions of people still lack access to safely managed sanitation services. This continues to pose major public health and environmental risks globally. Source
  3. Agriculture accounts for about 70% of global freshwater withdrawals. Food production is by far the largest consumer of freshwater resources. Source
  4. Population growth is increasing pressure on agricultural water systems. More food production requires more freshwater use. Source
  5. Dietary shifts toward more water-intensive foods increase overall water demand. Meat and dairy production require significantly more water than plant-based foods. Source
  6. Climate change is increasing the frequency and severity of droughts in many regions. This is already being observed across multiple continents. Source
  7. Many regions are expected to experience expanded drought risk under warming scenarios. Climate models consistently show increasing arid conditions in vulnerable areas. Source
  8. Groundwater depletion is occurring in many major aquifers worldwide. In many cases, water is being extracted faster than it can naturally replenish. Source
  9. The Ogallala Aquifer in the United States has experienced long-term declines in water levels across several regions. It remains a critical source of agricultural water under stress. Source
  10. Groundwater is a primary drinking water source for billions of people. It plays a crucial role in both urban and rural water supply systems. Source
  11. Sub-Saharan Africa remains the most water-insecure region in the world. Many countries face long-term challenges related to infrastructure and climate variability. Source
  12. Aging water infrastructure results in significant water loss due to leaks and inefficiencies. This reduces the amount of treated water that reaches consumers. Source
  13. Many populations live near stressed or polluted freshwater systems. This affects both water availability and water quality in affected regions. Source
  14. Many freshwater basins are shared between two or more countries. This makes international cooperation essential for sustainable water management. Source
  15. Water and energy systems are closely interconnected. Energy production requires water, and water treatment requires energy. Source
  16. Rising global energy demand is expected to increase water use in energy systems. This includes water used for cooling, extraction, and processing. Source
  17. Thermoelectric power generation is one of the largest users of freshwater in the United States. Cooling systems in power plants require large volumes of water. Source
  18. Industrial water demand is projected to rise with global economic growth. Manufacturing processes require large volumes of freshwater. Source
  19. Rapid urbanization is increasing demand on municipal water systems. Cities must expand their infrastructure to meet the growing needs of their populations. Source
  20. Global water stress is expected to intensify without major intervention. This is driven by climate change, population growth, and infrastructure strain. Source

Measurement is where water conservation begins.

Whether you’re managing irrigation on a farm, monitoring flow in an industrial process or tracking usage across a municipal system, accurate measurement is the foundation of every water-saving decision.
