The ongoing construction work of the advanced water purification plant at the eastern slope of the Songinokhairkhan mountain in the capital city is 99.5 percent complete.
Prime Minister of Mongolia Zandanshatar Gombojav, Mayor of the Capital City and Governor of Ulaanbaatar Nyambaatar Khishgee, and Ambassador Extraordinary and Plenipotentiary of the United States to Mongolia Mr. Richas Buangan visited the advanced water purification plant.
The “Water Supply Project,” with financing worth USD 461 million, is being successfully implemented with the grant from the Millennium Challenge Corporation (MCC) of the United States of America and investment from the Government of Mongolia. The advanced water purification plant is under construction at the eastern slope of Songinokhairkhan mountain within the framework of the project. The plant will purify up to 50 million cubic meters of water extracted from the western source of Ulaanbaatar to meet drinking water standards, supplying it to the central distribution network.
A team of 27 engineers and technical staff from the Water Supply and Sewerage Authority, responsible for operating the plant, participated in practical training in equipment installation and commissioning, and officially commenced their duties on July 31, 2025.
The MCC’s Water Supply Project will support the construction of new groundwater wells and a state-of-the-art plant for purifying drinking water as a western water source of the capital, the construction of a new plant for treating wastewater, and the development and implementation of policy, legal, regulatory, and institutional reforms to enhance the long-term sustainability of Ulaanbaatar’s water supply. The comprehensive implementation of the project will increase the water supply of Ulaanbaatar city by over 80 percent, creating favorable conditions for the westward expansion and economic growth of the capital city.
