TI recognizes that water is a precious resource – yet it is crucial to semiconductor manufacturing, which is why the company conserves and reuses water and works to preserve water quality to every extent possible.
We manage three types of water use globally that constitute our water footprint:
In order to conserve this natural resource, maintain water quality, and reduce our utility expense, we routinely identify and invest in new ways to reduce our consumption of water, reduce and/or segregate chemicals discharged, and recycle and reuse water.
The Audit Committee of the board of directors oversees our environmental compliance efforts and risk assessment process. The company's vice president of worldwide facilities and environmental, safety and health (ESH), who reports directly to our chief financial officer, oversees our water initiatives. These initiatives are coordinated and managed by the company's Water Process System team, which includes corporate environmental leaders as well as water quality, chemistry and system experts.
We use stringent management controls to monitor and reduce potential risks related to water quality, water supply, flooding and drought. Our Business Continuity and Water Process System teams monitor such risks and respond as needed.
Additional controls related to water use include:
Our water sources include surface water, groundwater and even collected rainwater, so we are sensitive to our potential impact on the water needs of communities where we operate. To evaluate and monitor water quality and availability, we periodically consult with local water authorities to assess their long-term storage and usage needs.
For example, our Texas sites, which make up the largest concentration of our operations, stay connected with the Texas Water Development Board and its survey activities. Since we are stakeholders in the Dallas Water Utility's long-range water-supply project, we participate in related public meetings and stay current on the project's status. This enables us to help shape the community's water supply well into the future and prepare our own operations accordingly.
Additionally, we routinely identify and implement mechanisms that improve water reuse and reduce overall consumption. Our innovations include installing waterless urinals to collecting rainwater for landscape irrigation.
We reclaim and recycle about a quarter of the water used in our manufacturing operations worldwide. This water is directed back into our system for reuse in cooling towers, scrubbers or in manufacturing.
Additionally, different locations present unique opportunities for creatively conserving water. Some of our water projects include:
We educate our workforce on how to reduce the size of TI's water footprint through our internal sustainability website, periodic intranet articles and educational activities during events such as Earth Week. We encourage employees to report leaks and to avoid running water unnecessarily.
