100 Climate Actions from Cities in Asia and the Pacific


Tajikistan’s capital is seeking to incorporate climate resilient measures in its water supply and sanitation infrastructure in order to increase the water security of its 863,000 residents.

Tajikistan, located amongst the mountains of Central Asia, is one of the region’s most climate vulnerable countries facing rainfall variation, extreme droughts, and disappearing glaciers. In Dushanbe, around 60% of water is currently lost due to leaks or theft, operation is intermittent at only 4–8 hours a day, and contamination is frequent.

The initiative aims to provide safe drinking water and improved sanitation in urban areas, a vital task in a city facing increasing water shortages under climate change. To do so, district metering areas will be introduced to reduce water loss through active leak detection and smart meters. Existing wells, pumps, and 17 kilometers of transmission main will also be rehabilitated, and protection will be put in place to safeguard groundwater well fields.



Flood risk management and drainage will also be enhanced, with an increased storage capacity of 4,500 cubic meters. Furthermore, improvements to a sewage collector in the southern part of the city will reduce contamination risks, especially during flood periods.

The $45 million project is made possible by a grant provided by ADB.

The Challenge

Rapid population growth and expansion have increasingly strained the city’s aging and poorly maintained water supply and sanitation infrastructure..


Health Improvements to sanitation services will reduce the incidence of waterborne illnesses like ascariasis and diarrhea in the project areas.

Economic Targeted consumers will receive cost savings from non-incremental water consumption with the switch to piped water from alternative sources.
