Water Resource Management
All operational sites of EGAT draw water from the Shimen Reservoir. The water sources consist entirely of municipal tap water, which is utilized for domestic consumption, on-site manufacturing processes, and cooling tower circulation. To optimize water efficiency, EGAT has implemented rainwater recycling systems across our maintenance facilities and manufacturing plants. This harvested water is dedicated to non-potable applications with no human contact, including cooling tower circulation and facility cleaning, highlighting our commitment to water recycling and resource circularity. In 2025, the total amount of rainwater harvested reached 1,432 metric tons. EGAT will continue to strengthen its water resource utilization strategy and optimize water-saving technologies to lower its reliance on natural water sources.
The total water withdrawal in 2025 was 242.25 million liters, representing an increase of 4.51% over the previous year. Although total water intake increased in 2025 as the scale of operations expanded, water intensity was 0.013, continuing a downward trend compared to previous years. To further enhance water efficiency, implement water resource management, and demonstrate concrete results, in 2025, in addition to continuing to review our operational water use, we further established short-, mid-, and long-term water intensity targets to strengthen water resource management efforts. In terms of effluents, plant effluents are managed according to local regulations. The drainage from the maintenance plant is directed through independent discharge outlets into the Puxin River or collected for centralized treatment at the airport sewage treatment plant before discharge, while the manufacturing plant's drainage is collected via industrial zone sewage pipelines and discharged after treatment at the industrial zone sewage treatment plant.
