Off-site domestic wastewater management system in Banda Aceh, Indonesia: the problems and future solutions concept

Abstract

Currently, Banda Aceh has been dealing with several problems related to pollution caused by domestic wastewater. According to previous studies, shallow groundwater and surface water in Banda Aceh have been contaminated by domestic wastewater produced by the community. The settlement scale off-site system with communal-WWTP operating in several villages has not function optimally in treating domestic wastewater. The problem also caused by service coverage which is still very small (only 2.12% of the total population). Therefore, it is require an acceleration of service improvement, by developing urban scale off-site system with centralized-WWTP and a wider pipe line network system. Moreover, further investigations are needed to develop the concept of planning as a preliminary design in the management of urban scale off-site system. This paper aims to develop a concept of domestic wastewater management using an urban scale off-site system that considers environmental characteristics in Banda Aceh as an alternative to mitigate the occurrence of water body pollution by domestic wastewater.
