Advanced in Smart Water Grid at Water Supply Systems: Principle and Application

Dear Colleagues,

The purpose of tap water was to provide an abundance of water for the first generation and safe and clear water for the second generation, but, in recent years, its purpose has been changing to the supply of healthy water with the development of ICT. To supply such healthy water, it is important to secure sufficient water resources, provide stable water quality, and supply water with sufficient minerals necessary for the human body. To achieve this goal, all water information on quantity and quality from water resources to water purification plants, water distribution systems, and households must be monitored. All water quality parameters including minerals must be accurately identified, and facilities must be operated optimally. To this end, a smart water grid (SWG), including information & communication technology (ICT), must be practically applied. SWG is an advanced water management technology and has recently attracted great attention worldwide. In this Special Issue, the process and principles of SWG were described. In addition, the intensive direction of SWG was suggested to enable optimal operation and maintenance when applied to the practical water supply systems.

The topics of interest for this Special Issue include but are not limited to the following:

1. Direction of SWG concept (recent and future)
2. Correlation between SWG and water welfare, and improvement direction of human life
3. Major factors of SWG, future standardization, and improvement directions (software, monitoring system, hardware, communication device, optimization and AI application, and consumer service)
4. Regulations and manuals for filed application of SWG
5. Analysis of pilot and actual application cases of SWG and suggestion of future directions
6. Current status of water supply systems (WSS) infrastructure and improvement direction for linkage of SWG application
7. Operation methodology of WSS in normal and emergency conditions after SWG application
8. Efficient maintenance of water infrastructure after SWG application
9. Strengthening of consumer service after SWG application
10. Analysis of economic effect and future trends of SWG application
11. Others: Various proposals and technology development for the spread of SWG application
