100 Climate Actions from Cities in Asia and the Pacific


Xinyu is adopting an integrated approach to flood control and waste management that seeks to safeguard communities against warming temperatures and increased precipitation.

The project aims to manage risks related to flooding and water pollution in the Kongmu River watershed, part of the larger Yangtze River Basin. The residents of Xinyu face some amount of flooding every year, which is expected to increase with climate change causing more precipitation in the region than the global average.


A comprehensive strategy has been developed that focuses on increasing flood retention capacities, improving sanitation services for communities, and protecting Xinyu’s water supply. 

The city will increase its resilience to flooding through rainwater interception and other stormwater management systems, and constructed wetlands will help treat runoff and improve water quality, while also acting as natural flood barriers. Water regulation structures, such as levees and interconnected storage lakes, and a wastewater collection network that operates separately from stormwater collection will also be established.

The project has a budget of $300 million, provided in part by an ADB loan.

The Challenge

The capacity of existing water and waste infrastructure is insufficient to handle population growth and flooding in the watershed area.


Environment The project’s green planning approach will reduce pollution from stormwater and waste, and will provide new green spaces for the public to enjoy.

Economic A number of construction jobs will be created by the project, benefiting local communities.
