Global freshwater withdrawals total about 2.5 trillion cubic meters per year, and food systems account for roughly 70% of that demand. Municipal use makes up just 9% of withdrawals, yet up to 30% of treated drinking water is still lost through leaking distribution networks. These statistics map the pressure points across water use, infrastructure losses, reuse, and access.
Key Takeaways
- 2,149 m³ per capita per year is the global average renewable freshwater availability
- 9% of freshwater withdrawals are for municipal use
- Food systems account for about 70% of global freshwater withdrawals (including production and supply chain)
- Up to 30% of treated drinking water is lost to leakage in distribution networks in many systems (OECD framing; common loss benchmark)
- Recycling and reuse of water in industry can reduce freshwater withdrawal needs by 30% to 60% in many industrial applications (World Bank Water Reuse guidance)
- Membrane bioreactor systems can achieve 90% to 99% removal of suspended solids in wastewater treatment (peer-reviewed ranges)
- By 2050, global water withdrawals are projected to increase by 55% (OECD/FAO baseline projection)
- In sub-Saharan Africa, 10.5 million people lack access to at least basic drinking-water services (WHO/UNICEF JMP)
- The global water treatment chemicals market is projected to reach $16.9 billion by 2028 (marketsandmarkets)
- The global desalination market is projected to reach $20.0 billion by 2030 (Fortune Business Insights)
- The global water and wastewater treatment market size is forecast to reach $503.7 billion by 2030 (IMARC Group)
- As of 2022, 26% of the global population lacked safely managed sanitation services (WHO/UNICEF JMP)
- The UN SDG 6.4 target aims for substantial increases in water-use efficiency and sustainable withdrawals by 2030
- EU Water Framework Directive requires member states to achieve good status of water bodies by 2027 on average (directive objective for planning cycles)
- 2.5 trillion cubic meters per year is the global freshwater withdrawal volume estimate used in water stress and water-use accounting across major assessments.
With water demand rising fast, improving efficiency and recycling could sharply cut withdrawals and expand safe access.

02
Recycling and reuse of water in industry can reduce freshwater withdrawal needs by 30% to 60% in many industrial applications (World Bank Water Reuse guidance)
03
Membrane bioreactor systems can achieve 90% to 99% removal of suspended solids in wastewater treatment (peer-reviewed ranges)
04
USGS estimates that 2015 irrigation efficiency improvements reduced withdrawals by about 1.2% vs. if efficiency had not improved (USGS water-use accounting comparisons)
05
Industrial water reuse can reduce wastewater discharge volumes by up to 70% in well-designed systems (OECD/industry report on reuse)
Interpretation
Efficiency And Losses Interpretation
Across the Efficiency And Losses category, the biggest wins come from cutting waste and maximizing treatment performance, with leakage alone driving up to 30% losses in distribution networks and water and wastewater reuse and advanced treatment often cutting freshwater withdrawals or discharge by roughly 30% to 60% and up to 70% respectively.

Water Use By Sector4 stats
01
2,149 m³ per capita per year is the global average renewable freshwater availability
02
9% of freshwater withdrawals are for municipal use
03
Food systems account for about 70% of global freshwater withdrawals (including production and supply chain)
04
Approximately 1.8 billion people use drinking water services that are contaminated with feces (WHO/UNICEF JMP, 2017 estimate)
Interpretation
Water Use By Sector Interpretation
From a Water Use By Sector perspective, the largest share of freshwater withdrawals goes to food systems at about 70%, while municipal use is only 9% and 1.8 billion people still rely on drinking water contaminated with feces, showing how sector-level demands and water quality issues are tightly linked.
