Arizona's Chip Manufacturing Industry Faces Water Scarcity Challenges
Arizona is facing a growing water scarcity issue due to the declining flow of the Colorado River, which supplies over a third of the state’s water. This shortage threatens industries reliant on large volumes of water, including semiconductor manufacturing. Companies like TSMC and Intel are expanding chip fabrication facilities in Arizona with federal support under the CHIPS and Science Act, but these operations require significant amounts of ultra-pure water for production processes. The situation is intensifying as climate change exacerbates drought conditions across the region. While agriculture remains the largest consumer of water (over 70% of usage), chip manufacturing—though currently using only about 6%—is growing rapidly and becoming more resource-intensive due to its reliance on municipal water for purification processes. City planners, industry leaders, and policymakers are grappling with how to allocate limited resources fairly. The rising cost of infrastructure needed to adapt is creating tensions over who should bear the financial burden.
