The water intake at WT’s operating sites are mainly used for circulated water of air conditioners and daily-life water consumed by employees in office and storage areas. The water is entirely sourced from the local water companies (fresh water) where each operating base is located, with no significant impact on water resources and the ecological environment of water source areas.

In order to ensure drinking water safety for employees, the water dispenser filters are replaced every month to effectively remove harmful substances in the water. Taiwan SGS is commissioned to regularly test the water every year to ensure safe and healthy water quality. The water consumption is mainly contributed by the evaporation and drift losses from air-conditioners and the water drunken by employees, and there is no effective tool available to measure them. The water discharge is solely made up of water used by employees in the daily life and is discharged into local public sewage systems through the sewage pipes of the building. An assessment conducted by WT following the Water Risk Atlas of the World Resources Institute (WRI) found that the operating sites in Taiwan, Hong Kong, and Singapore are not in areas with water stress (high or extremely high). The total water intake was 21.32 million liters in 2023, an increase of 8.37 million liters from 2022, due to the expansion of statistical scope.
