Smart Water Network Management

Definition of SWNM (Smart Water Network Management)

optimal management technology to build and operate a tap water supply system that can take preemptive and active action in the event of accidents, such as water leaks and abnormal water quality, and reduce water leaks by combining IoT and AI technologies in the entire tap water supply process .

Definition of SWNM (Smart Water Network Management)

SWNM Project Overview

Domestic SWNM Achievements

Successfully promoted the modernization of water supply systems in 82 localities in Korea

Local Water Supply Modernization Status : Improvement of flow rate: before and after the project / Secure water resources (reduced leak): 110 million m3/year reduced | secured water worth Boryeong Dam / Economic effect: economic effect induced, 1.1 trillion KRW/year / Carbon reduced: 20,000 pine trees > 4.6 times the World Cup Stadium  27,531tCO2/year

SWNM Project Effects

  • Reduced leaks : Fee revenue increases through leak reduction and water supply expanded to non-supplied area
  • Stable water supply : Stable water supply by securing appropriate water pressure and preventing leaks
  • Water quality management : Supply clean tap water through real-time water quality monitoring
  • Systematic water pipe network management : Establish a scientific and systematic water pipe network management system
