Dedicated Water Supply System Combining Multiple Sources is Key Solution for Semiconductor Industry, Not Single Dam

Discussions are intensifying among experts following the government's announcement of a plan to supply 650,000 cubic meters of industrial water daily to the southwestern semiconductor industrial complex. The proposed plan has brought several critical issues to the forefront, including the technical and environmental feasibility of raising the Dongbok Dam, potential conflicts with current water users, concerns over the water quality required for semiconductor manufacturing, and the overall reliability of the supply system.

While raising the Dongbok Dam by 15 meters has been presented as the most effective way to secure a substantial water volume, it faces significant controversy. Debates center not only on its technical viability but also on issues like compensation for submerged land, the long-term stability of the water supply, and the need for a revamped operational framework. Some experts argue that even with the dam expansion, it might be difficult to fill the reservoir completely due to drought conditions.

However, proponents of the dam expansion highlight its high turnover rate, with annual inflow approximately 2.2 times its total storage capacity. The core challenge, they contend, is not merely filling the reservoir but ensuring a reliable supply that accounts for climate change. Water quality concerns also require careful reassessment, particularly in the context of the stringent requirements for semiconductor production.

An alternative solution gaining traction involves establishing a dedicated water supply system that integrates multiple water sources. This approach aims to mitigate the risks associated with relying on a single dam and provides a more robust and flexible strategy for meeting the significant water demands of the semiconductor industry. Such a system would need careful planning to balance the needs of various stakeholders and ensure environmental sustainability.
