In order to cope with the muddy water, damaged water quality and aquatic ecology which can be caused in the process of the Four Major River Restoration Project, K eco establishes the monitoring, prevention and control tasks.
Major Tasks
- Install and operate the Water Quality Conservation Center for the Four Major River Restoration Project to prevent water quality from being contaminated
- Offer human resources, technical education and control support training to prevent water quality from being contaminated
- Monitor/prevent water contamination by building the Water Contamination Control Information System
Control Equipment Status
- 5 Air-Cushioned Landing Crafts, 1 Oil Spill Response Vessel, 5 Oil Skimmers, 5 Mobility Maneuverable Vehicles (16 units in total)

Ecological Toxicity Control System
The Ecological Toxicity Control System aims to examine the hazardous materials in the effluents of the industrial wastewater and to effectively manage their effect on the aquatic ecology. The water fleas were selected as the test sample and put in the effluent to see if they can survive more than 24 hours. This result is described in the TU (Toxic Unit) to represent the level of the ecological
Major Tasks
- Technical support to the business sites in the field of the ecological toxicity control on the industrial water quality
- Policy support and the Ecological Toxicity Control System promotion
- Online information website for the Ecological Toxicity Control System management
Water Quality Auto Monitoring Network Management for the Water Source and Four Major River Project
The Water Quality Auto Monitoring Network is installed in the major streams and lakes by the rivers under the Four Major River Project and the status of the water quality is measured and monitored 24/7 in real-time. This is to prevent water contamination, and if contamination is detected, it adopts the prompt countermeasure. It is an environment monitoring network to protect the water quality of the water supply source.
Major Tasks
- Install and manage the water quality auto monitoring network in 56 places of the Four Major Rivers water system
- Monitor the water contamination via the river water quality monitoring system, collect monitored data and offer the analyzed data
- Establish the early alert system to cope swiftly to the possible water contamination accident
Monitoring Items
- Common Items
- Mercury, pH, DO, electrical conductivity, TOC
- Optional Items
- Biological toxicity (fish, water flea, birds, microorganism), volatile organic compounds (VOCs), total nitrogen (T-N), total phosphorous (T-P), chlorophyll-a, ammonia nitrogen (NH3 -N), nitrate nitrogen (NO3 -N), phosphate (PO4 -P), turbidity, phenol, heavy metal
Water Quality Remote Monitoring System (WaterTMS) Control Center
K eco manages and inspects the quality of the effluent from the public sewerage/wastewater treatment facility and wastewater discharge business sites nationwide all year round and offers the result to the administrative organization and the corresponding business site to prevent the water contamination accidents and control the pollutants systematically.
Water Quality Remote Monitoring System (WaterTMS)
- K eco connects the public sewerage/wastewater treatment facility and wastewater discharge facilities nationwide and the consecutive auto monitoring device attached to the final drainage outlet of the emission business sites of the tertiary up to the primary grade with the Water Quality Remote Monitoring Control System online to monitor the discharge status of the water pollutants 24/7.
Major Works
- Operate the Water Quality Remote Monitoring (WaterTMS) Control System
- Provide technical support for stable management of the Water Quality Remote Monitoring System (WaterTMS)
- Provide technical support to the technical support centers in the corresponding area of four districts (Seoul metropolitan area/Chungcheong area/Honam area/Yeongnam area) Technical support
Monitoring Items
- pH, organic matter (BOD or COD), SS, T-N, T-P
