Water Consumption

Ta Ya Group withdrew water from municipal potable water and harvested rainwater. In 2024, the Group's total water withdrawal was 231,353 tons, a decrease of 26,693 tons compared to 2023, representing a 10.34% reduction. This decline was mainly driven by Ta Ya Company, which reduced water consumption by 27,506 tons compared to the previous period.

 

Water Resource Risks

Ta Ya adopts the Aqueduct Water Risk Atlas to assess water risks at its operational sites. Based on the evaluation, Hai Duong and Kunshan sites are located in areas of high water stress and are classified as water-risk sites.

 

Waste water treatment

In 2024, the Group discharged 125,534 tons of wastewater to water treatment plants and then into nearby water bodies and discharged 12,270 tons of wastewater to water treatment plants. All production sites regularly conduct water quality testing to ensure that discharged water does not impact local water bodies or ecosystems.

Ta Ya has established the Water Pollution Prevention and Control Operating Procedures, defining operational standards and control measures for wastewater treatment processes at the Guanmiao Headquarters to meet environmental regulations. Ta Ya also commissions government-approved environmental testing agencies to regularly test the water quality of on-site water and effluents, with periodic reporting. Wastewater from the Guanmiao Site is treated internally before being discharged into roadside ditches, ultimately flowing into the Erren River Basin. Wastewater from Cuprime flows into the Fusen Stream, while wastewater from the Taipei Branch, Union Storage, and Ta Ya Venture Capital is treated by the New Taipei Industrial Park Wastewater Treatment Plant. UEI's wastewater is discharged to the wastewater treatment plant in the southern area of Huaya Industrial Park.

 

Water Saving Initiatives

To conserve water and monitor the condition of water tanks, Ta Ya has established inspection checklists and conducted weekly inspections. Future inspections will be extended to cooling towers and air compressors, with items under development. Other water-saving measures at operational sites include:

1.Rainwater harvesting project.
2.Water circulation and recycling in the mixing plant.
3.Water circulation and recycling in the tin plating plant.
4.Wastewater recycling in the paint production line.
5.Rainwater and wastewater separation project under planning.
