The seriousness of water related issues is increasing due to regional imbalances of water use and damages from water related disasters. Various technologies are being applied to resolve water related issues. Recently, interest in SWM, water management methods converging with ICT, is increasing. K-water, as a Korean government owned corporation, suggested SWMI as a new paradigm to resolve water related issues by converging K-water's experienced water management know-how with advanced ICT. SWMI is an integrated management model covering the entire water cycle from sources to tap for securing the stability, safety and efficiency of water. At the same time, a 3-step strategy consisting of technology development, standardization and standardized frame for application of technologies was established to implement SWMI. It is expected that SWMI will enable scientific and efficient water management by interacting of technologies converged with ICT for entire water cycle from sources to tap water.
