K-water has been actively researching and developing advanced IWRM (Integrated Water Resources Management) and SWG (Smart Water Grid) as practical measures to respond to climate change. In order to resolve issues such as flooding and droughts which are becoming worse, to secure the stability of water service despite of increased uncertainty in water management, and to settle water related conflicts between districts that arise as a result of climate change, K-water adopts IWRM though we set forth to consider not only the technical aspects but also the economy, society, and environmental issues in order to realize water management which maximizes both the national economy and welfare. Also, we diversify the sources of water through use of ICT (Information and Communication Technologies) in order to more securely and efficiently supply and manage water resources, and adopt SWG which can increase the efficiency of water supply while consuming less energy.
