Project to Reuse Treated Wastewater for Landscape Irrigation (Recycle)

The Company implements effective wastewater management measures by reusing water that has been treated to meet legal standards, thereby reducing the use of municipal water. The treated water is primarily reused for irrigating plants within the hospital premises. This project has been implemented continuously, including the installation of a recycle water filtration system to improve the efficiency of water reuse. However, in early 2025, the volume of recycled water used for plant irrigation decreased due to the accumulation of sediments mixed in the wastewater, which caused blockages in the pipeline system and reduced the amount of water available for reuse. Based on an annual water usage assessment, only approximately 650 cubic meters of water per year could be reused, representing a decrease of 357 cubic meters per year compared with the previous level. To address this issue, the Company installed an additional wastewater filtration unit to capture sediments and contaminants before entering the pipeline system, thereby improving water flow efficiency.

Performance Results (March 1 – December 31, 2025)

• The project increased the volume of recycled water used for irrigation by 281 cubic meters.
• The estimated full-year performance is expected to reach approximately 1,007 cubic meters of recycled water per year, significantly reducing the consumption of municipal water.
