As part of Ulaanbaatar’s 24 mega development projects, the Tuul Water Complex is scheduled for construction between 2025 and 2032 on a site covering 5,569 square meters.
Currently, the capital relies entirely on groundwater, consuming between 185,000 and 225,000 cubic meters of freshwater per day. By 2040, daily water demand is expected to increase to 772,450 cubic meters. To address this, a flow-control dam will be built on the Tuul and Terelj rivers, enabling the city to shift from groundwater to surface water usage. In preparation for this project, three to four potential locations for the dam’s spillway have already been identified.
The Tuul water complex will have the capacity to store between 50 and 100 million cubic meters of water. The dam will measure 685.15 meters in length, 35.8 meters in height, and have a sediment depth of 19.84 meters.
Once completed, the complex will help protect the capital from flood risks, provide a stable drinking water supply, support the ecological balance of the Tuul River, and contribute to energy generation. The project is expected to play a key role in ensuring Ulaanbaatar’s water security and environmental sustainability in the long term.
