Water Resources

Wistron's production processes mainly consist of product assembly which does not involve the use of a great amount of water. Most of the water demand is for domestic use and plant equipment such as kitchens and cooling towers. Based on our evaluations, Wistron's use of water resources and the ecological environment of water sources will not create significant environmental impact. Nevertheless, Wistron still actively collects water consumption data and regularly monitors water quality and consumption conditions. We organize water conservation campaigns from time to time for the purpose of protecting water resources.

Wistron’s management of water resources can be divided into “implementation of water resource management and day-to-day water conservation” and “implementation of water recycling and wastewater management”. We conduct an inventory of high-risk areas for water resources based on an evaluation of the water stress indicators of our global operations. We then implement preventive measures based on the water resource management strategy.

Wistron's water use target in 2021: Reduce water consumption intensity by 9% compared to 2016 and implement more ambitious goals for 2022, 2025, and 2030, and continuous tracking to disclose the water saving performance of each year.
