Taiwan's Da'an-Dajia river water link begins operation early, hailed as 'great spatial rearrangement'

Central Taiwan's water supply is now more secure thanks to the early completion of the Da'an and Dajia river inter-basin water transfer project. The project officially began supplying water on July 25, six months ahead of its original schedule, a feat celebrated by Premier Cho Jung-tai.

Cho described the project as a "marriage" between the Da'an and Dajia rivers and a "great spatial rearrangement" of water resources. He emphasized that this initiative guarantees a stable water supply for the central region. The project connects water sources like the Liyutan Reservoir and Shiqian Dam through pipelines, enhancing supply capacity, backup capabilities, and water distribution efficiency for the greater Taichung area.

This is a marriage of the Da'an and Dajia rivers, and even more so a 'great spatial rearrangement' project that will ensure water security for the central region.

This inter-basin connection is a key component of Taiwan's national "Pearl String Plan." Once fully realized in three years, this plan aims to link 16 major water transfer pipelines across the island. This network will allow water to be shared between regions, ensuring that any area facing shortages can receive support from others. Cho highlighted the ambitious nature of this plan, noting that few countries possess such a comprehensive, island-wide water distribution system.

The Da'an-Dajia river project, which commenced in April 2023, overcame significant geological challenges, including fault lines, by employing shield tunneling methods. This approach minimized disruption to daily life and industrial activities. The successful and timely completion underscores Taiwan's commitment to robust water resource management and infrastructure development.

North water south transfer, south water north transfer, central water north and south delivery. This is the basic concept of the Pearl String Plan.
