TSMC has faced water use issues in the past and has established various water recycling strategies. TSMC is collecting air conditioning condensate water and rainwater to augment its supply and is building water reclamation plants.
The company states on its website that in 2019 the average recycling rate of the water used in production processes reached 86.7 percent and the total amount of water recycled by TSMC reached 133.6 million tons.
The website also states there is a 2021 goal for a water reclamation plant in Yongkang, Tainan – in the south of Taiwan – to be able to provide TSMC with 5,000 tons of water per day and for another water reclamation plant at TSMC Tainan Science Park to be able to provide 5,000 tons of water per day.
It is not clear whether those steps and others being taken are enough to meet the demands to curtail water use being placed upon TSMC. The alternative will be for TSMC to choke back wafer processing adding to global supply chain problems.
Taiwan as a whole was responsible for 21.8 percent of global chip supply in 2018 ahead of South Korea with 21.3 percent. These two places are homes to TSMC and Samsung, respectively.
