The water used by all factories is tap water, and no groundwater is used. Water consumption is primarily for domestic use, air conditioning cooling, and a small amount for laboratory use. Large water volumes are not needed. Using the World Resources Institute’s “Aqueduct Water Risk Atlas” risk assessment tool, the water risk level of each factory location has been identified. All factories are located in areas with low to moderate water stress, and are not situated in water-stressed regions. Therefore, there is no significant impact on water resources or the ecological environment of water sources.

The total water intake in 2024 was 80,793 tons, and the water intensity was slightly lower by 0.76% compared to 2022, failing to meet the 6% reduction target. This was due to the expansion of operations, including personnel and equipment, at the Hsinchu Plant II and increased facility usage at the Taiyuan Plant and Zhongxing Plant. Consequently, the overall water intensity target for 2024 was not achieved. We recommend continuing to implement a water resource management strategy focused on “reduction,” “reuse,” and “recycling” to improve water resource efficiency.
