Life on Earth is based on water. The quality of life directly depends on water quality. Every year, 1,500 cubic kilometers of wastewater is produced globally. While waste and wastewater can be reused productively for energy and irrigation, it usually is not. In developing countries, 80 percent of all waste is discharged untreated because of lack of regulations and resources.
In 1992, the U.N. General Assembly adopted a resolution designating March 22 of each year as World Water Day.
UN-Water has chosen "Clean Water for a Healthy World" as the theme for World Water Day 2010. The campaign aims to raise the profile of water quality at the political level so that water quality considerations are made alongside those of water quantity.
China will launch the 23rd China Water Week from March 22 to March 28 with a theme of "Water resources management for maintaining sustainable development." Many events will be organized across the country.
