Abstract

As of 2017, the United Nations has estimated that there are 68.5 million displaced people in the world which live in refugee camps (RCs) in 125 host countries. RCs frequently encounter water scarcity issues which lead to a low daily limit of water consumption, as well as face management difficulties such as septic tank overflowing which contribute to the development of health problems. Considering the need for more sustainable water, sanitation, and hygiene system in RCs, a socio-eco-efficiency analysis (SEEA) framework is proposed for the analysis and comparison of different wastewater treatment methods. The SEEA framework consists of the integration of the economic and environmental aspects analysed by an eco-efficiency analysis (EEA) with the social aspects evaluated by a social life cycle assessment (S-LCA) using the analytic hierarchy process. The SEEA framework was applied to compare different wastewater treatment methods in Zaatari Refugee Camp in Jordan. The SEEA results show that, if adopted, an effluent water reuse-based treatment would increase economic efficiency by 75%, decrease environmental impacts by 57%, and increase social sustainability by 57% compared to the current operation of the camp, where a wastewater system connects groups of seven to nine households to communal septic tanks. A ternary diagram is used to represent the comparison of different wastewater treatment methods for an RC. The diagram shows the degree of socio-eco-efficiency of each wastewater treatment method, in terms of its social impacts, environmental impacts, and cost by normalising results of the EEA and S-LCA into one score.
