Water Resource Management
The source of water utilized by PAHSCO is supplied by Taiwan Water Corporation. Currently, under the influence of extreme climate conditions, the dry season is becoming increasingly prolonged. To mitigate the risk of water shortages, PAHSCO has implemented several measures, including condensate water recovery, reclaimed water reuse, an increase in the circulation rate of cooling towers, and the recycling of process water, all while ensuring compliance with legal regulations and park specifications. These initiatives have significantly reduced overall water consumption. As of 2025, the water recovery rate has consistently remained above 70%.
In addition, in order to avoid the impact of wastewater on the community environment, PAHSCO has set up a wastewater treatment monitoring system to control the quality and quantity of wastewater, and appoints qualified testing vendors to conduct wastewater quality test every 6 months and declare the results in accordance with the regulations. In 2025, all wastewater discharged from PAHSCO complied with the discharge standards of the HSPB.
