Water for Mongolia

The Fraunhofer Institute (Germany) has devised high-tech monitoring to improve Mongolia's water supply, just one of the numerous startling projects undertaken by this innovative organization: Clean water is a rare commodity in many countries of the world and governments often face problems ensuring its reliable supply. In Mongolia, an interdisciplinary research team is demonstrating how this vital resource can be efficiently managed and used. Specially developed software help to detect weak points in the supply system.

….Providing a clean supply of drinking water across the entire country is a difficult challenge – beginning with the need to lay freeze-proof water pipes over an area of 1.5 million square kilometers. The people in the countryside therefore use water from rivers, or from wells that they dig themselves. But these traditional ways of obtaining water are reaching the limits of their capacity….

"Providing a supply of drinking water is becoming more and more difficult. To create a reliable supply in the long term you have to take many different factors into account and find out how they influence each other," explains Dr. Buren Scharaw from the Fraunhofer Application Center System Technology AST in Ilmenau. Born in Mongolia, he has been working for many years on the a project entitled "Integrated Water Resources Management for Central Asia: Model Region Mongolia", known also as MoMo. ….. The model region under study by the research scientists is the catchment area for the Kharaa River and Darkhan, a city of 100,000 inhabitants.

Since the start of the project, in 2006, Scharaw has traveled back to his homeland several times. He has examined the quality of the water from public and private wells along with the distribution network, measured the energy consumption of pumps, and investigated the effectiveness of the sewage system. All of the data he has meanwhile collected has been fed into the computer models developed at Fraunhofer AST. "Our HydroDyn water management solution makes it possible for the first time to visualize the quality as well as the quantity of water resources and to model their future development," the scientist explains.

There is plenty of scope for improvement: the water pumps consume lots of energy, the water pipes are in need of repair and nearly half of the drinking water is lost on its way to the consumer because of leaks. Many yurts have their own wells, but the water is often contaminated with bacteria from latrines. What can be done? "Having collected data and produced models we are now preparing proposals that make sense in economical and ecological terms", says Scharaw. His team has developed a software program for the purpose which can determine how the water supply can be sustainably secured using less energy.

… In three years’ time, when the MoMo project has been completed, the experts intend to present the government administration in Darkhan with a catalogue of measures which will show how the water supply and sewage system can be efficiently and cost-effectively secured. Scharaw regards it as one of his major successes that he prompted the Mongolian authorities to discontinue mining operations in some regions of the Kharaa catchment area – an achievement that extends far beyond improving the drinking water supply in Darkhan.
