About World Water DayWorld Day for Water, or unofficially World Water Day (WWD), occurs each year on March 22, as designated by United Nations General Assembly resolution.

This day was first formally proposed in Agenda 21 of the 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil.

Observance was expected to begin in 1993 and has grown significantly ever since.

The UN invited its member nations to devote this day to implementing UN recommendations and promoting concrete activities within their countries.

Each year, one of various UN agencies involved in water issues takes the lead in promoting and coordinating international activities for WWD.
