The multi-regional water supply system is a facility designed to provide water to more than two local governments. It is equipped with large-scale pipelines and water treatment facilities. This facility is recognized as the most efficient way of allowing the whole nation to evenly enjoy the benefits of water, to achieve balanced regional development, and to help remove the problem of water shortage even during relatively long droughts. In the future, K-water will build a better relationship with the public by offering better services, which can be achieved through systematic construction and management of multi-regional water supply systems.
In order to resolve water shortages in some regions, and to create efficient countermeasures to weather problems such as drought, an integrated management system has been established to provide water for drinking/industry/agriculture by dividing the nation into 9 areas to cope with emergency situations through mutual assistance. Moreover, K-water continues its utmost efforts in supplying safer and cleaner water through improvements of water supply facilities and system automation, which also leads to lower costs and improved efficiency.

The plan seeks to enhance water supply coverage to 97.9% by 2025. Also, small and medium-sized water supply systems for rural areas will be continuously constructed to solve the imbalance of water supply among different regions. K-water will constantly build multi-regional water supply systems to improve the quality of life for the whole nation and to create a drought-proof environment by providing clean and safe water to any location nationwide.
