Abstract
In South Korea, in line with the increasing need for a reliable water supply following the continuous increase in water demand, the Smart Water Grid Research Group (SWGRG) was officially launched in 2012. With the vision of providing water welfare at a national level, SWGRG incorporated Information and Communications Technology in its water resource management, and built a living lab for the demonstrative operation of the Smart Water Grid (SWG). The living lab was built in Block 112 of YeongJong Island, Incheon, South Korea (area of 17.4 km2, population of 8000), where Incheon International Airport, a hub for Northeast Asia, is located. In this location, water is supplied through a single submarine pipeline, making the location optimal for responses to water crises and the construction of a water supply system during emergencies. From 2017 to 2019, ultrasonic wave type smart water meters and IEEE 802.15.4 Advanced Metering Infrastructure (AMI) networks were installed at 527 sites of 958 consumer areas in the living lab. Therefore, this study introduces the development of SWG core element technologies (Intelligent water source management and distribution system, Smart water distribution network planning/control/operation strategy establishment, AMI network and device development, Integrated management of bi-directional smart water information), and operation solutions (Smart water statistics information, Real-time demand-supply analysis, Decision support system, Real-time hydraulic pipeline network analysis, Smart DB management, and Water information mobile application) through a field operation and testing in the living lab.

Summary
The ultimate goal of Water Distribution Network (WDN) management is to provide consumers with a safe, reliable, and sustainable water supply. The EU carried out its ICT Solutions for Efficient Water Management (ICeWater) project and the Water Innovation through Dissemination Exploitation of Smart Technologies (WIDEST) project supported by the European Commission These projects are aimed at improving the energy efficiency of urban WDNs through real-time water consumption monitoring and reducing water loss by developing leak detection technologies for pipelines [8]. In South Korea, for the implementation of SWG technology, the country is taking pioneering steps to build a hyper-connected smart city by carrying out a local water supply modernization project and constructing and operating a water industry cluster To this end, the Smart Water Grid Research Group (SWGRG) was launched in 2012 to build an intelligent water management system using alternative water resources with the aim of reducing water and energy consumption.
