Yes, semiconductor plants use a lot of water, but the vast majority is recycled and returned
Construction of two large semiconductor fabrication plants in Phoenix by the Taiwan Semiconductor Manufacturing Company, or TSMC, is expected to result in a major boost for the city’s economy. But questions are being raised about whether there is an adequate supply of water to support the company’s vast operations. Paul Westerhoff, a professor of civil and environmental engineering in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, says he is confident that recent engineering innovations can help, specifically through the use of recycled wastewater systems. He notes TSMC is already planning to build an on-site water reclamation plant for its manufacturing operations.
