하수저류시설 타당성 분석 연구

Abstract

In the era of climate change, the feasibility of a 'multi-functional storage facility' was evaluated in terms of various key performance indices such as flooding prevention effects, urban pollution reduction effects, and rainwater harvesting effects. As a result, the Korea Ministry of Environment introduced a new concept of 'multi-functional storage facility' for sewer flooding prevention and urban non-point pollution reduction. Prior to introducing these infrastructure (a large underground storage facility), the more details were needed to examined carefully in terms of technical aspects of construction and management. It is also well known that the validity of installation of 'multi-functional storage facility' was sometimes weakened because of low B/C ratio.
