Water Resource Usage<\/h2>\n\n\n\n
The company's Linkou plant, located in Hwa Ya Industrial Park, receives its main\nwater supply from Shimen Reservoir, with wastewater discharged to the South\nWastewater Treatment Plant managed by Hwa Ya Consulting Co., Ltd. The\nXinzhuang plant also sources its water from Shimen Reservoir, with wastewater\ndischarged to Bali Wastewater Treatment Plant. According to the Water Resource\nRisk Assessment Tool, the company's water resource risk is classified as medium to\nlow risk.
The company has long focused on water conservation and environmental protection.\nIn its water-saving plan, the company emphasizes daily water conservation practices\nand actively improves the water consumption of its processes to maximize the use of\navailable water resources.<\/div>\n\n\n\n
