World Water Day: Why Wastewater?

Water is the essential building block of life. But it is more than just essential to quench thirst or protect health; water is vital for creating jobs and supporting economic, social, and human development.

Today, there are over 663 million people living without a safe water supply close to home, spending countless hours queuing or trekking to distant sources, and coping with the health impacts of using contaminated water.

Theme: Why Wastewater?

This year, we focus on wastewater and ways to reduce and reuse as over 80% of all the wastewater from our homes, cities, industry and agriculture flows back to nature polluting the environment and losing valuable nutrients and other recoverable materials.

We need to improve the collection and treatment of wastewater and safely reuse it. At the same time, we need to reduce the quantity and pollution load of wastewater we produce, to help protect the environment and our water resources.

Facts on World Water Day
  • Globally, over 80% of the wastewater generated by society flows back into the ecosystem without being treated or reused. (Sato et al, 2013)
  • Better health
    Clean water allows better hygiene and sanitation and reduces exposure to waterborne diseases that sicken hundreds of millions of people a year.
  • Economic growth
    The burden of disease and premature death is lessened by water access, which lets people devote more time to productive activity and emerge from poverty.
