Taiwan Semiconductor Manufacturing Company (TSMC), the world’s largest contract microchip maker, said it has initiated measures such as reducing water usage and trucking in water for some facilities this week as a test run to prepare for “possible future needs.”
“So far there is no impact on production and we are monitoring the water supply situation closely,” the company said in a statement.
TSMC has said the auto industry was a top priority but warned its factories were already at full capacity.
A science park in northern Hsinchu city said other semiconductor companies were making similar preparations for water restrictions.
The dry spell came as no typhoons made landfall in Taiwan last year for the first time in 56 years.
Water levels in some reservoirs are at below 20 percent, and the central weather bureau predicts “drier than usual” weather for this month and next.
The government has “prepared for the worst,” said economic affairs minister Wang Mei-hua, as an “orange alert” has been issued to limit total water use and reduce water pressure in some cities.
