World Water Day is marked on 22 March every year. It’s a day to celebrate water. It’s a day to make a difference for the members of the global population who suffer from water related issues. It’s a day to prepare for how we manage water in the future, reports unwater.org.

In 2015, the theme for World Water Day is 'Water and Sustainable Development'. It’s about how water links to all areas we need to consider creating the future we want.

In 1993, the United Nations General Assembly designated 22 March as the first World Water Day. Twenty-two years later, World Water Day is celebrated around the world shining the spotlight on a different issue every year. This issue is also the theme of the annual UN World Water Development Report which is launched on World Water Day.

Each year, UN-Water provides resources to inspire celebrations for World Water Day.
