This paper studies on the applicability of an alternative wastewater management by installing constructed wetland with vegetation and ecological lifestyle to reduce pollution of domestic effluent, in a remote island, Ogi Island in Setouchi, Japan, where the population is declining and the infrastructure has been old and difficult to maintain. By reviewing literature and clarifying the features, it is found that the alternative wastewater management can be applied to Ogi Island, since there is enough space for it, and it is more economical, and possible to be maintained by community members, comparing with installing septic tanks.
