South Korea Confronts Water Crisis for Semiconductor Future
A staggering 100 million metric tons of water—equivalent to Hong Kong’s entire annual consumption—fuels the global semiconductor industry each year. For South Korea, a nation officially designated as water-stressed since 1995, this figure represents an existential threat to its most advanced industries. This critical challenge is the central focus of the Korea International Water Week (KIWW) 2026, which opens tomorrow at Daegu’s EXCO, bringing together global experts to find a solution.
The summit’s theme, “Water, Energy, AI: Securing Our Future,” sets an urgent tone for the three-day event running from September 9th to 11th. At the heart of the discussions is the convergence of water, energy, and artificial intelligence (AI) to secure resources for vital sectors like semiconductors. Co-hosted by the Ministry of Climate, Energy and Environment, Daegu Metropolitan City, and K-water, KIWW 2026 is positioned as a key battleground for resolving the nation’s pressing water security issues.
Semiconductor Water Demand Surges, AI Offers Solutions
Despite its world-leading competitiveness, South Korea’s semiconductor industry has a glaring vulnerability: water. Samsung Electronics’ domestic facilities alone guzzled an average of 344,000 tonnes of water daily in 2022, and the combined thirst of Samsung and SK Hynix has surged 40% in just six years. This is not just a local trend; globally, the industry’s demand is projected to hit a colossal 2 billion tons by 2035. The crisis is already here, with water supply issues delaying national mega-projects like the Yongin semiconductor cluster and the proposed Honam complex facing the daunting task of securing 650,000 metric tons of water per day.
The challenge goes beyond mere quantity. Advanced chipmaking requires ultrapure water—a substance scrubbed of all impurities—and here, Korea’s dependency on foreign technology is a critical weakness. Relying on imported equipment and operational systems for this vital resource creates a significant supply chain risk, making domestic technological self-reliance an urgent national priority. A dedicated KIWW session, titled “Water-Energy-AI: Enabling the Future of the Semiconductor Industry,” is set to tackle these technological hurdles head-on.
Artificial intelligence is emerging as the critical enabler for overcoming these water challenges. AI algorithms can parse vast datasets to predict leaks in aging supply networks, fine-tune water treatment processes, and preemptively flag equipment failures for more efficient maintenance. Beyond just fixing problems, AI sharpens demand forecasting and optimizes resource allocation, driving down operational costs and boosting sustainability. For the energy-intensive water treatment sector, this translates directly into higher efficiency and a smaller carbon footprint.
Integrated Strategies for Future Competitiveness
Recognizing the scale of the crisis, the South Korean government is initiating a comprehensive overhaul of its decade-old National Water Management Master Plan. This move signals a fundamental paradigm shift, treating water with the same flexible, adaptive planning typically reserved for the national power grid. K-water is already making tangible progress, developing advanced technologies to purify wastewater from sewage treatment plants back to a reusable standard—a vital step in reducing the semiconductor industry’s footprint and bolstering national resilience against scarcity.
South Korea’s future as a global semiconductor powerhouse is inextricably linked to an integrated water, energy, and AI strategy. Aggressively deploying AI in water management, achieving self-sufficiency in ultrapure water production, and maximizing wastewater reuse are no longer just environmental goals; they are fundamental pillars of national industrial competitiveness. Both the government and the private sector must now accelerate investment in these technologies and actively seek international collaboration. The solutions and alliances forged at this year’s Korea International Water Week will mark a critical juncture, shaping the trajectory of the nation’s entire industrial landscape.
