Water Resource Usage
本公司營運之林口廠位於華亞工業園區中，其自來水主要供水源取自石門水庫，排水地點於華亞園區管理顧問股份有限公司南區污水處理廠；新莊廠，其自來水主要供水來源取自石門水庫，排水地點於八里污水處理廠，依據水資源風險評估工具，本公司水資源風險列為中低風險。
本公司長年關注水資源節能環保議題，在節水計畫方面，從全面落實日常生活節約用水做起，並積極改善製程耗水量，將可利用之水資源發揮更大效益。2025年單位用水量為4,861公噸，較2024年6,131公噸減少20.71%，顯示用水效率持續提升。未來將持續推動節水措施，並以2026年用水量較2025年再降低1%為目標，進一步強化水資源管理成效。

Notes:
- Water discharge data is recorded monthly by the Hwa Ya Park Service Center from the company’s effluent flow meter and logged in the Hwa Ya Technology Park Industrial Wastewater Inflow Detail Table.
- Water Consumption = Water Withdrawal -Water Discharge.
- Water Intensity Calculation: Water Withdrawal (million liters) / Organization Specific Metric Value.
Wastewater Testing
Statistics and Standards for Wastewater Discharge and Monitoring Values of Linkou Plant over the past three years. Although the Company does not have monitoring data for discharge outlets or monitoring equipment, we strictly comply with regulations. An activated carbon adsorption tower is installed at the outlet, and the activated carbon is replaced at least once a year as required by the Water Pollution Control Measures Plan and Water Pollution Control Permit.
