Water covers 71% of the Earth's surface. A single cell of Escherichia coli contains 70% of water, a human body 60–70%, plant body up to 90% and the body of an adult jellyfish is made up of 94–98% water.
Thus it can be said that the colorless and odorless damsel forms an integral part of one’s life. Water is also considered as a symbol of purification. International World Water Day is held every twelve months to focus the attention on the importance of freshwater and to promote sustainable management of freshwater resources.

United Nations Conference on Environment and Development (UNCED) decided to observe an international day to celebrate freshwater in 1992 and thus the first World Water Day was observed on 22 March 1993.
World Water Day is celebrated every year with a new theme highlighting an explicit aspect of freshwater.
Today one in every eight people in the world don’t get pure water inspite of spending hours by women and children in collecting water from distant resources.
This day gives an opportunity to remember our commitment to achieve the day when everyone in the world can have safe drinking water and also to celebrate the progress of bringing about 3 lakh people in eight countries clean water and sanitation.
Themes of World Water Day Yester YearsWorld Water Day is celebrated every year with a new theme highlighting an explicit aspect of freshwater.
