World Water Day is celebrated every March 22nd as a way to draw attention to the importance of freshwater for human consumption and to raise awareness for sustainable management of water resources.
A day to celebrate freshwater was the subject of special interest to the United Nations Conference on Environment and Development (UNCED) in 1992.
