As part of the 24 Mega Projects for Ulaanbaatar City Development, the Tuul Water Complex will be built between 2025–2032 on a 5,569 square meter area.
Currently, Ulaanbaatar City’s residents rely 100 percent on groundwater, using between 185,000 to 225,000 cubic meters of clean water per day. By 2040, daily water demand is projected to increase to 772,450 cubic meters. To meet this rising demand, flow-regulating dams will be constructed on the Tuul and Terelj rivers, enabling the use of surface water through the development of the Tuul Water Complex. Preliminary studies have identified 3–4 potential dam site options.
The Tuul Water Complex will have the capacity to store 50–100 million cubic meters of water. The planned dam will be 685.15 meters long, 35.8 meters high, and 19.84 meters deep at its deepest point. The Complex is intended to serve multiple purposes, including protecting the capital city from flood risks, ensuring a reliable source of drinking water, maintaining the ecological balance of the Tuul River, and generating electricity.
