Taiwan Semiconductor Manufacturing Co. (TSMC) has broken ground on a 15-acre industrial water reclamation plant (IRWP) at its north Phoenix campus. The facility is designed to recycle up to 90% of wastewater generated by its chip fabs, a move that aligns with the company’s sustainability goals and Phoenix’s long-term water planning.

The IRWP is engineered to achieve “near zero liquid discharge,” enabling TSMC to reuse nearly every drop of water. Once operational in 2028, the plant will initially recycle approximately 85% of the wastewater, with a goal of reaching 90%. That level of reuse equates to the annual water consumption of roughly 12,000 single-family homes.
