Selaru Island is one of the small and outermost islands in Tanimbar Islands Regency, Maluku Province, Indonesia. Domestic and mining activities cause its population to grow rapidly and the migration to the center of activities in the regency/city leads to higher demand of clean water, particularly water derived from groundwater, which affects the water table. The purpose of this study is to conduct water resource management in Selaru Island using technological approaches. This study is expected to complement other studies related to water resource management in small and outer islands. A form of water resource management that can be carried out is using technological approaches such as retention basin, rainwater harvesting, and groundwater. The results of implementing technological approaches show that Selaru Island will have an increase of population to 59,676 people in 2038 and it will require 164,841 water tanks with the capacity of 5m3/unit. Water resource management in small outer islands such as Selaru Island necessitates the integration of stakeholders as decision makers, community participation, and academicians to achieve sustainability of the program and its implementation.
