Water Resource Usage
The company's Linkou plant, located in Hwa Ya Industrial Park, receives its main
water supply from Shimen Reservoir, with wastewater discharged to the South
Wastewater Treatment Plant managed by Hwa Ya Consulting Co., Ltd. The
Xinzhuang plant also sources its water from Shimen Reservoir, with wastewater
discharged to Bali Wastewater Treatment Plant. According to the Water Resource
Risk Assessment Tool, the company's water resource risk is classified as medium to
low risk.
The company has long focused on water conservation and environmental protection. In its water-saving plan, the company emphasizes daily water conservation practices and actively improves the water consumption of its processes to maximize the use of available water resources.

Water Resource Risk Assessment
Linkou Plant Water Usage in the Past Three Years
| Year | 2022 | 2023 | 2024 |
|---|---|---|---|
| Water Withdrawal | 5.53 | 6.29 | 6.13 |
| Water Discharge | 1.89 | 2.42 | 2.57 |
| Water Consumption | 3.64 | 3.87 | 3.56 |
| Organization-Specific Metric (Unit) | Revenue (Million NTD) | Revenue (Million NTD) | Revenue (Million NTD) |
| Organization- Specific Metric Value | 519.781 | 668.281 | 628.688 |
| Water Intensity | 0.0106 | 0.0094 | 0.0098 |
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.
