Blockizing the Sangsu Water Network and Unifying Inflow Points per Block
Expecting Stable Operation by Enhancing Analysis Efficiency of Water Pressure and Leakage
Yongin City in Gyeonggi Province is embarking on the establishment of a 'block system' to ensure stable tap water supply and efficiently respond to water outages.

On the 2nd, Yongin City announced that it recently held a kickoff meeting for the 'Yongin City Block System Construction and Specialized Maintenance Service for Water Supply Network' aimed at stable tap water supply.
The block system is a water supply system that divides the complexly intertwined water supply network into several blocks, unifies the water inflow points of each block, and installs flow and pressure meters. By establishing this system, clean tap water can be supplied stably, and the damage range caused by water outages due to emergencies such as water quality issues or disasters can be minimized. Additionally, the city explained that it is advantageous to be able to check real-time flow and pressure, monitor leaks, and analyze water supply efficiency for stable water supply.
In particular, for blocks with low water supply efficiency, rapid cause analysis through leak detection is possible, which can reduce tap water production costs and secure the efficiency of water supply network operation, the city added. Water supply efficiency refers to the ratio of the amount of water actually supplied to citizens and charged as fees to the total tap water production. A low water supply efficiency means that a large amount of tap water is lost in the middle and not supplied to citizens.
Until last year, the city invested about 12 billion KRW to complete the block system construction project in 51 out of 86 sub-blocks. The city plans to invest an additional 2.4 billion KRW by 2026 to newly establish 22 sub-blocks. By 2028, the city aims to build the block system in all areas to systematically maintain the water supply network.
A city official said, "Through the block system construction and specialized maintenance project for the water supply network, we expect to reduce leakage and lower tap water production costs," adding, "We will strive to establish a virtuous cycle structure for the water supply business and provide citizens with high-quality tap water."
