World Water Day
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.
The world commemorated World Water Day on March 22 with events around the globe focusing on ways to make international cooperation happen in the water. Events held in celebration of the Day covered all aspects of water - from water supply and sanitation, to water and its nexuses with food and energy, water resources management and water and climate change. But in most, if not all of these events, one theme was clearly cross-cutting: the importance of strengthening partnerships to leverage knowledge and facilitate innovative solutions.

Today, water is the star. Once a year, we celebrate it, we sing its praises, we think about it. Once a year, we pause to consider the ominous and worrying statistics. Then the curtain falls and we move on. On to another show, another issue to be brought to light.
Dr. Robert Kibugi is a Legal/Institutional Expert for Ministry of Water and Irrigation in Kenya and a lecturer at the Centre for Advanced Studies in Environmental Law and Policy (CASELAP), University of Nairobi.
Legal and institutional changes in the Kenyan water sector are not new; the current water law was enacted in 2002. The law introduced extensive changes and reforms, including a separation between water resource management and water services that allows specialized agencies to perform the tasks.
This resulted in creation of the Water Resource Management Authority (WRMA) to manage and regulate water resources, and the Water Services Regulatory Board (WASREB) to regulate water services. The latter regulates the functions of Water Services Boards (WSBs), responsible for developing infrastructure, and those of water service providers (WSPs), which are primarily utilities that purchase water from WSBs and sell to consumers. Beyond water services and resources, the areas of water storage and irrigation, which address harvesting and productive use of water, were not part of the 2002 reforms.
Yesterday, on the eve of World Water Day, NASA and the United States Geological Survey released the first images from the thermal imaging band of its latest launch of the LANDSAT satellite. The satellite will begin regularly producing data on May of this year. Why does that matter? It is the latest improvement in a technology that, in my opinion, has the power to revolutionize water management around the world.
Given that World Water Day, March 22, is not even underway in a large part of the world, at the time of this writing, the amount of World Water Day coverage is no small thing. Here is how World Water Day (eve) has unfolded across the World Bank’s social media and websites.
This year’s World Water Day (March 22) focuses on cooperation around water, so it’s a good time to reflect on lessons that those of us working on cooperation in international waters can learn from the experiences and accomplishments in water cooperation in the Nile Basin.
Water is at the crux of several development challenges, from health impacts related to poor sanitation and drinking water, to food and energy shortages caused by poor water management. We’ve also heard leaders such as US Secretary of State Hillary Rodham Clinton describe water as a means for peace.
And investments in water are working. Last week, UNICEF and WHO announced that over 2 billion people gained access to safe drinking water between 1990 and 2010, meeting the Millennium Development Goal for increased access to water three years ahead of target. During this same timeframe, 1.8 billion people gained access to improved sanitation.
