World Water Day
Water is a renewable, but finite, resource and its importance is nearly immeasurable.
World Water Day is celebrated every year at the behest of the United Nations as a means of focusing international attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.
The 2017 theme is "Why Wastewater?" and focuses on reducing and reusing wastewater. The United Nations has set as one of its sustainable development goals to halve the quantity of untreated wastewater around the world (currently 80% of all wastewater is not treated) and to dramatically increase the reuse of "gray water"—water that has not come into contact with fecal matter.
