“Do what you can do, do it with others and, do it with passion” Guy Ryder chair of UN-Water
What is World Water Day?
World Water Day, on 22 March every year, is about taking action to tackle the water crisis. Today, 1.8 billion people use a source of drinking water contaminated with faeces, putting them at risk of contracting cholera, dysentery, typhoid and polio.
The Sustainable Development Goals, launched in 2015, include a target to ensure everyone has access to safe water by 2030, making water a key issue in the fight to eradicate extreme poverty.
In 1993, the United Nations General Assembly officially designated March 22 as World Water Day. World Water Day is coordinated by UN-Water in collaboration with governments and partners.
Globally, the vast majority of all the wastewater from our homes, cities, industry and agriculture flows back to nature without being treated or reused – polluting the environment, and losing valuable nutrients and other recoverable materials.
Instead of wasting wastewater, we need to reduce and reuse it. In our homes, we can reuse greywater on our gardens and plots. In our cities, we can treat and reuse wastewater for green spaces. In industry and agriculture, we can treat and recycle discharge for things like cooling systems and irrigation.
By exploiting this valuable resource, we will make the water cycle work better for every living thing. And we will help achieve the Sustainable Development Goal 6 target to halve the proportion of untreated wastewater and increase water recycling and safe reuse.
• Globally, over 80% of the wastewater generated by society flows back into the ecosystem without being treated or reused.
• 1.8 billion people use a source of drinking water contaminated with faeces, putting them at risk of contracting cholera, dysentery, typhoid and polio.
• Unsafe water, poor sanitation and hygiene cause around 842,000 deaths each year.
• 663 million people still lack improved drinking water sources.
• By 2050, close to 70% of the world’s population will live in cities, compared to 50% today.
• Currently, most cities in developing countries do not have adequate infrastructure and resources to address wastewater management in an efficient and sustainable way.
• The opportunities from exploiting wastewater as a resource are enormous. Safely managed wastewater is an affordable and sustainable source of water, energy, nutrients and other recoverable materials.
• The costs of wastewater management are greatly outweighed by the benefits to human health, economic development and environmental sustainability – providing new business opportunities and creating more ‘green’ jobs.
