Taiwan Launches Major Irrigation Network to Enhance Water Supply in Central and Southern Regions

WATER INFRASTRUCTURE & DESALINATION

Taiwan's Ministry of Agriculture has launched a major irrigation network at the Chiayi-Yunlin border, projected to enhance the annual water supply by 70 million tonnes. This system connects the Tsengwen and Wushantou Reservoirs with the Zhuoshui River, utilizing an aqueduct across the Beigang River.

It will mitigate irrigation interruptions due to variable rainfall by channeling water during high-flow periods and drawing from reservoirs during low-flow periods. The project, completed two years early, includes 12 new irrigation ponds and aims to stabilize water supply for agriculture in Yunlin, Chiayi, and Tainan, which represent over one-third of Taiwan's agricultural output. The initiative also supports water recycling and desalination efforts.
