Remember when you were a kid and everyone asked: “What do you want to become when you grow up?” What did you answer? Have you fulfilled your dreams?
Most of us aspire to live our lives to the fullest; to develop our talents; to make a difference in the world. Sometimes we may feel lost in the great scheme of things. But as the World Bank Group’s Jim Yong Kim points out: The most successful movements to change the world started with a small group of like-minded people. Think of the movements to find a treatment for AIDS, to promote human rights or to ensure gender equality.
In the unsettling horror movie Alien, an alien invades and hides within the human body, eventually causing great devastation. This is like the real story of the parasitic worm that, within minutes, invades the human body, using its forked tails to burrow into skin. Once inside the human body, it travels through the bloodstream and lives off its nutrients.

On a warm Friday afternoon in the slums of Madhukam, in the heart of Ranchi, India, a middle-aged man arrived at a public water station with two 20-liter containers to fill. The water station - directly adjacent to an open sewage drain - was really just a concerete wall with four pink spigots protruding from its barren surface. On top perched two large, seemingly empty holding tanks of water. The man placed one of his containers under the first spigot and turned the handle. A small flow of water came out. Within a minute, the flow turned into a trickle, and the trickle quickly became nothing. The man moved to the next spigot, and then the next, only to have all four repeat the same pattern. In the end, the man left carrying only six ounces of water in his two 20-liter containers.

China’s most arid regions are facing an increasingly serious water crisis, and local water policies often aggravate the problem. In such climates, growth in the agricultural sector has come with high environmental costs.
With the help of new technologies that measure real water consumption in agriculture, governments are designing innovative water rights systems that actually save water. Based on results from two successful pilots, the World Bank Group is partnering with China to tap into science to transform water management in agriculture at the national level.
In the Middle East and North Africa (MENA) region there is really very little choice. The region only receives about two percent of the world’s annual precipitation and holds about 1.2 percent of the world’s renewable water resources. This makes water a deeply precious and scarce resource. The statistics are stark: The amount of water consumed in the United States averages 2,800 cubic meters per person per year, whereas in Yemen, it is 100 cubic meters per person.
The theme of this year’s #worldwaterday focuses on water and energy. And for good reasons.
For the last six years, a power plant in San Luis Potosi, Mexico has bought water from a nearby wastewater treatment plant to use in its cooling towers (instead of using freshwater). This operation, Project Tenorio, a public-private partnership, continues today and has already resulted in the reduction of groundwater extraction of at least 48 million cubic meters (equivalent to 19,000 Olympic size pools) and increased aquifer sustainability.
This is a good example of the water and energy nexus in practice: the wastewater treatment plant covers almost all of its operating costs from this additional revenue stream and the power plant gets a more reliable water source that is also 33% cheaper than groundwater in that area.
Treated wastewater has been used to reduce the water requirements of power plants in several other countries as well, as water supply becomes more variable or disappears. In the US, for example, around 50 power plants are using treated wastewater for cooling in order to adapt to water shortages. However, innovative integrated approaches like these are still more of an exception than the norm.
