The first World Water Day, designated by the United Nations, was in 1993.
UN-Water is the convener for World Water Day
The UN World Water Development Report (WWDR) is released each year around World Water Day.
The day is used to advocate for the sustainable management of freshwater resources.
The theme for 2021 was "Valuing Water" and "a conversation about what water means to you".
The theme of each day focuses on topics relevant to clean water, sanitation and hygiene (WASH), which is in line with the targets of Sustainable Development Goal 6.
