[Asia Economy Reporter Jongil Park] Seongdong-gu (Mayor Jeong Won-oh) has established an 'Underground Space Leakage Diagnosis System' and started tackling water supply leaks this month.

The 'Underground Space Leakage Diagnosis System' is an advanced technology that installs sensors in water supply manholes to detect abnormal signs such as vibrations caused by leaks.

By utilizing Internet of Things (IoT) wireless communication, the measured data is analyzed from multiple angles and monitored in real-time 24/7, allowing for early detection of water supply leaks. When abnormal signs are detected, they are marked in red on the map along with risk levels. Suspected leak locations are promptly inspected by relevant agencies to ensure immediate action.

Following the enactment and enforcement of the 'Special Act on Underground Safety Management' (January 2018), which was established to prevent safety accidents caused by ground subsidence such as sinkholes, the district has continuously maintained and managed unused water pipes and joints in the water supply system.

In particular, this year, smart innovative technologies that can preemptively eliminate causes such as road collapses have been actively introduced, with a total of 30 sensors installed throughout the district. Priority areas have been selected, and installation locations will be changed at least every two months to prevent various road safety accidents caused by leaks in advance.

Furthermore, the plan is to gradually expand the installation of this technology not only to water supply but also to railway structures, groundwater inflow paths, sewage systems, and other underground facilities, enhancing its utilization for systematic management to prevent road collapses.

Jeong Won-oh, Mayor of Seongdong-gu, stated, “As urban infrastructure develops, urban safety management has become even more important. We will actively adopt innovative and smart technologies to create an efficient and systematic urban safety system and do our best to ensure safety.”
