Samsung Electronics, the Ministry of Environment, Gyeonggi Province, and public and private sectors are working together to repurpose sewage treatment water into industrial water. While solving the national issue of water scarcity by supplying the world’s biggest scale of industrial water for semiconductors from 5 sewage treatment plants, it is also able to simultaneously improve ‘environmental, social, and governance (ESG)’ management.
The Ministry of Environment revealed that the ‘Business Agreement for Sewage Treatment Water Reuse Activation’ was signed at the Samsung Electronics Hwaseong Campus on the 30th with the attendance of related government institutions, such as K-water and Korea Environment Corporation, and relevant local governing bodies in the Gyeonggi Province.
With this business agreement, 5 sewage treatment plants in Suwon, Suji, Giheung, Dongtan, and Osan will repurpose their treatment water into industrial water for semiconductor manufacturing and supply roughly 474,000 tons of treatment water daily. This is the biggest in scale globally and is equivalent to the amount of tap water used by all of the citizens in the Gwangju Metropolitan City in a day (around 484,000 tons). As this will replace dam water, it is expected to be able to secure 170 million tons of surplus water annually, which is comparable to the storage capacity of Namgang Dam (180 million tons).
The Ministry of Environment plans to use this business agreement to lay the foundation to provide reused water for semiconductor manufacturing processes, a cutting-edge industry that uses highly purified water, expand places of demand for reused treatment water, and expand the supply base.
Gyeonggi Province and local governing bodies will be able to receive supply payments from companies that use repurposed sewage water, not only helping with regional finances, but it is also expected to help invigorate the regional economy through reuse facility installment projects.
Samsung Electronics, which will be supplied with treated sewage water, is projected to be able to implement ESG management and be stably supplied with water even in times of severe droughts. In particular, it is expected that there will be advantages in reducing management risks in cases of emergencies, such as water supply restrictions.
