Water
We focus on conservation, recycling and high standards for wastewater treatment and discharge.
Actions
Our Facilities and Manufacturing Teams have made great strides in identifying additional opportunities to increase water recycling and finding ways to optimize processes.
Recycling and Reduction
We implement projects that collect and recycle water at our manufacturing sites. This reduces the amount of incoming water consumption, reduces our reliance on local water supplies and makes our operations more efficient. In addition to our water recycling efforts, we look for opportunities to reduce our overall water consumption.
Wastewater
We are committed to returning water to the environment that is as clean as or cleaner than what we sourced. We set our effluent-discharge standards to meet or exceed local discharge requirements based on the profile of the receiving water body. Our water-pollutant identification and classification process also varies by region and site.
Water Aspiration
Semiconductor manufacturing, especially wafer fabrication, is a water-intensive process. To reduce incoming water consumption, we focus on a mid-term goal of increasing our water recycling rate to 60% by 2027. In 2025, our wastewater recycling increased by 6 percentage points to 61%.
With this recycling rate, we have achieved our water recycling target ahead of our original commitment.
Water Stress
We assessed water stress at all our manufacturing sites. According to the WRI, two of our manufacturing sites — Chandler and Bangkok — are classified as high or extremely high baseline water stress. However, we currently do not experience issues accessing sufficient water resources for our operations.
More information about the risk of water stress and our mitigation measures can be found in our TCFD Index.
2025 Results
Our decade-long focus on water conservation has emphasized the use of more efficient tools. In 2025, our water withdrawal decreased by 10% compared to 2024. This decrease is due in part to the additional opportunities to increase water recycling and process optimization our Facilities and Manufacturing Teams have identified.
Wastewater Excellence Award
The two manufacturing sites in Texas, Austin (ATMC) and Oak Hill, received the city of Austin's 2025 award for Excellence in Wastewater Pretreatment (based on 2024 performance). The award honors significant industrial water users who exhibit environmental stewardship by proactively preventing pollution and managing wastewater discharge. This is the eleventh consecutive year for ATMC to receive the award and the tenth for Oak Hill.
