World Water Day, coming up on Wednesday, is an annual event first established by the United Nations in 1992 to focus on the importance of freshwater and to encourage actions to provide clean drinking water while reducing water-borne illness around the world.
This year’s theme, waste water, was formulated into a question that creates a double meaning. It can be either “Why waste water?” or “Why wastewater?” The first question emphasizes the water-supply issues associated with World Water Day. The second emphasizes the closely related health aspects of sanitation. For a serious discussion of these two questions, listen to the talk on YouTube by Guy Ryder, director general of the International Labour Organization and chairman of UN-Water.
