B.Bymbasaikhan: Dam of flood protection will be built in four location in 2025

The Department of Geodesy, Water Construction, and Structures of Ulaanbaatar City, in  cooperation with the Head of the Office of the Capital Governor and the Mayor’s Office of Ulaanbaatar city is presenting  a work plan for 2025. As of today, there are about 168 km of flood dams in Ulaanbaatar. In the general development plan of Ulaanbaatar until 2040, it is planned to expand the flood structure of Ulaanbaatar to about 450 km.

As part of the project, Head of the Department of Geodesy, Water Construction and Structures of Ulaanbaatar City B. Byambasaikhan reported about the construction of flood protection dams in four locations in 2025.

First, the Jargalant flood protection dam, or 1.8 km flood dam, which has been in operation for more than a year, will be handed over to the state commission. Last year, the construction of the flood protection structure of the National Center for Maternal and Child Health and the General Archives was completed. The entire work will be completed this year with the construction of the 420-meter-long flood protection dam, which will connect to the Jargalant.

Second, the earthen flood protection channel that went east from Circle line 32, Committee of 12 in the Sukhbaatar district to the Selbe River has lost its ability to penetrate water due to a lack of engineering design. Therefore, the line will be repaired with engineering design.

Thirdly, the dam  wall collapsed due to a flood in th 16 committee of the Bayangol District, Bombgor area. The 40-meter vertical retaining wall will be reconstructed and poured again.

Fourth, the Aviation flood channel will be repaired and upgraded. The feasibility study, geodesy, topographic mapping, engineering and geological survey, detailed environmental impact assessment, detailed design work of roads and bridges, engineering and geological surveys of bridge structures, bicycle, and pedestrian paths for the “Selbe Revival” project have been completed.

To protect against flood risks and restore the flow of the Selbe River, a reservoir with a volume of 1.3 million cubic meters will be built in the middle part of the river, in some parts of Bayanzurkh and Sukhbaatar districts, where flood water accumulates more. The reservoir will cover 21.7 hectares of area, 2.5-4 meters deep, and construction is planned to begin this April.
