RCS (Remote Control Station)
- Consists of a logic unit, control unit, input/output (I/O) modules, communication modules, power modules, and related components
- Installed at field sites such as intake stations, water treatment plants, and booster stations, it collects measurement signals from equipment and transmits them to the central control center, while also performing automatic and remote control of pumps, valves, and other equipment
TM/TC (Tele-Mornitoring/Tele-Control)
- Remote monitoring and control equipment used to monitor and control remote individual business sites, branch points, and inflow points of blocks through wired and wireless communications
- Performs functions such as collecting signals from facilities and measuring instruments and processing control commands
Transmission Equipment / Communication Network
- K-water has introduced an ultra-high-speed communication network and established and operates a network infrastructure capable of transmitting data rapidly
- Through the ultra-high-speed communication network, collected data are transmitted and analyzed in real time to improve the operational efficiency of water supply facilities and enable rapid response when problems occur
- With a redundant wired and wireless configuration, the system switches to a backup network in the event of a primary network failure, thereby ensuring the stability of the water supply control network and strengthening security
This is a description of the transmission equipment and communication network configuration diagram. It illustrates the overall architecture of a high-speed communication network infrastructure designed to transmit and analyze operational data in real time, collected from water facilities such as water treatment plants and pumping stations. Through a dual-redundant configuration of wired and wireless networks, the system can immediately switch to a backup network in the event of a primary network failure, ensuring uninterrupted data transmission and maintaining the stability and security of the water control network.

Expected Effects
Improved Work Productivity for Operations Managers
- By establishing the same water-operation system (iWater) at each business site, the workload associated with job rotation is reduced and ease of task execution is improved
Ease of System Implementation and Maintenance
- As standard screens, water-treatment facility symbols, and related components are provided by default, the system implementation period is shortened
- By eliminating dependence on external vendors for system maintenance, in-house software engineering strengthens IT capabilities and reduces costs
Providing a Foundation for u-IT Future and Core Technology Development and Reducing Costs
- Based on iWater, application software can be developed to provide an optimal operation-management solution for water supply business sites, and the system can be expanded and applied across the entire platform
* Because all business sites are based on iWater, application software development and deployment are easy to carry out
- Overview It helps water supply business sites quickly identify and prevent or respond to both major and minor accidents and process errors. When an alarm occurs, it minimizes unnecessary alarms through user-defined algorithm analysis and provides decision-making information such as real-time identification of causal factors and resolution cases.
