The proper operation and safety management of water and wastewater treatment systems are essential for providing stable water service to the public. However, various natural disasters including floods, large storms, volcano eruptions and earthquakes threaten public water services by causing serious damage to water and wastewater treatment plants and pipeline systems. Korea is known as a country that is relatively safe from earthquakes, but the recent increase in the frequency of earthquakes has increased the need for a proper earthquake management system. Interest in research and the establishment of legal regulations has increased, especially since the large earthquake in Gyeongju in 2016. Currently, earthquakes in Korea are managed by legal regulations and guidelines integrated with other disasters such as floods and large storms. The legal system has long been controlled and relatively well managed, but technical research has made limited progress since it was considered in the past that Korea is safe from earthquake damage. Various technologies, including seismic design and earthquake forecasting, are required to minimize possible damages from earthquakes, so proper research is essential. This paper reviews the current state of technology development and legal management systems to prevent damages and restore water and wastewater treatment systems after earthquakes in Korea and other countries. High technologies such as unmanned aerial vehicles, wireless networks and real-time monitoring systems are already being applied to water and wastewater treatment processes, and to further establish the optimal system for earthquake response in water and wastewater treatment facilities, continuous research in connection with the Fourth Industrial Revolution, including information and communications technologies, is essential.

본 연구는 하천의 수자원 조절에 이용되는 보에 대한 환경영향을 전과정평가 기법을 이용하여 정량화 하였으며, 적용된 보의 규격은 각각 500 mm (H) × 15,000 mm (L), 2,000 mm (H) × 15,000 mm (L)로 공압식 고무보와 직립형 고무보이다. 지구온난화의 범주에서 특성화 값을 비교한 결과 500 mm (H) × 15,000 mm (L) 규격에서는 공압식고무보는 5.365E + 05 kg CO 2 -eq, 직립형고무보는 5.441E + 055 kg CO 2 -eq를 각각 배출하는 것으로 나타났으며, 2,000 mm (H) × 15,000 mm (L)의 경우에는 2.193E + 06 kg CO 2 -eq, 직립형 2.094E + 06 kg CO 2 -eq로 분석 서로 상반되는 결과를 보여 주었으며, 이는 고무보와 직립보의 규격과 건축방법이 환경영향에 가장 큰 영향을 주는 것을 의미하고 있다. 특히, 운전에너지와 원부자재가 환경영향 민감도 분석에서 가장 큰 영향인자로 나타났다. 따라서 하천구조물과 같이 내구년한 이 긴 시스템일수록 온실가스 저감을 위해서는 환경영향에 대한 사전평가가 고려되어야 한다. The aim of this study was to quantify the environmental impacts of dams, used for the control of riverine water resources, through life-cycle assessment techniques. The studied pneumatic and upright rubber dams had sizes of 500 mm (H) × 15,000 mm (L) and 2,000 mm (H) × 15,000 mm (L), respectively. The characterization values of the dams were compared in view of global warming. If the pneumatic and upright rubber dams both had sizes of 500 mm (H) × 15,000 mm (L), they would emit 5.365E + 05 kg CO 2 -eq and 5.441E + 055 kg CO 2 -eq, respectively. Meanwhile, if they both had sizes of 2,000 mm (H) × 15,000 mm (L), they would emit 2.193E + 06 kg CO 2 -eq and 2.094E + 06 kg CO 2 -eq, respectively.These results indicated that the environmental impact of dams can be strongly influenced by their size and construction method. In particular, their operating energy and the characteristics of their raw and subsidiary materials were the highest-ranked environmental impact factors in our sensitivity analysis. Therefore, in order to reduce greenhouse gas emissions, the environmental impact of river structures with a relatively long lifetime should be pre-evaluated when their construction is being planned.
