The Thailand National Pilot Project handover ceremony was held on September 11, marking a milestone in the Korea–UNDP Phase 3 Cooperation Project focused on sustainable water management in the Mekong region. The project successfully transferred an intelligent, data-driven water management system to Bueng Khla, enhancing water supply reliability for over 950 households and saving 24 cubic meters of water daily. Local government leadership, international cooperation, and tailored technology were key to the achievement. The event coincided with the UN Day for South-South Cooperation, highlighting the role of innovation in community development.
