SWNM Project Overview

① Survey/Analysis

On-site survey and establishment of a pipe network

* On-site survey on water supply facilities, subsequently planning on block and pipe network maintenance, to be used as basic data, and pipe network construction technology for water supply maintenance

DMA Planning

Classification of the water supply monitoring system (large-medium-small), division of appropriate blocks comprehensively considering topography (roads, river, etc.), water use, water pressure, and facility installation plan review (flowmeter, block boundary, etc.)

② Block construction

Installation of facilities, including control valves for managing flow rate, PCL, etc., according to appropriate block division plans

③ Water leak management

Core NRW reduction technology to check underground leak locations using equipment and sensors

④ Water pressure management

Leak reduction and securement of supply stability by setting the proper water pressure for high pressure and excessive water pressure deviation areas

⑤ Monitoring Maintenance

Setting effective and systematic pipe maintenance section through hydraulic, water quality diagnosis, and pipe status evaluation

⑥ System Build-up

Construction of a monitoring and surveillance system for real-time monitoring of facility operation data (flow rate, water pressure, and quality)
* Establishment of a monitoring and management system for systematic flow rate management, such as flow rate, MNF analysis, etc.

⑦ Water Quality Management

Establish a water quality management facility to supply clean water

Domestic SWNM Achievements

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

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
