In order to improve living conditions in a safe and healthy environment and to reduce flood risks, the Groundwater and Flood Protection Project is planned to be implemented across six districts of the capital city.

Under the project, the most deteriorated and frequently damaged sections of Ulaanbaatar’s centralized wastewater network will be rehabilitated using modern trenchless technology. Specifically, a total of 39,469 meters of wastewater pipelines will be restored through trenchless methods. This technology enables the creation of a new internal lining within existing pipes without extensive excavation of streets and public spaces, thereby enhancing structural integrity and extending service life.

Within the framework of the project, pipeline lining and partial expansion works are planned as follows: 7,909 meters in Bayanzurkh district, 9,892 meters in Sukhbaatar District, 3,561 meters in Chingeltei district, 8,810 meters in Bayangol district, 6,607 meters in Songinokhairkhan district, and 2,690 meters in Khan-Uul district.

The Groundwater and Flood Protection Project will be implemented in compliance with the World Bank’s Environmental and Social Framework and Environmental and Social Standards (ESS2–ESS10).

Upon completion, the project is expected to reduce incidents of wastewater overflow, mitigate flood risks, and decrease soil and environmental pollution. It will also improve public health conditions and enhance the sustainability of urban infrastructure. Furthermore, the initiative is anticipated to improve the quality of residents’ living environments, strengthen the city’s capacity to manage increasing wastewater loads, and align with the capital’s sustainable development strategy by delivering high investment efficiency and long-term benefits for urban livability.
