Abstract

Recent serious of flooding events in urban area have brought a growing concern on storage facilities as a major stormwater management method. The Korean Ministry of Environment has announced diverse plans to tackle the problem, including plans for multi-purpose storages which deal both the stormwater and wastewater. Even though storages can be categorized for different perspectives, classification of possible storages in urban area has not been throughly studied so far. This study investigated diverse references of urban storages and suggested systematic classifications on structural, functional and some other basis. Structural classification mainly concerns structural shape of facilities and includes ①Cisterns & Rain barrels, ②Forebays, ③Dry basins, ④Wet basins and ⑤Constructed wetland. Those functions can be ①flood prevention ②water quality control and ③reuse of stored water. Other criteria that categorize storages depend on ①height, ②location, ③configuration, ④depth, ⑤site of the installation and ⑥shape.
