Sustainability is a serious problem in rural water supply systems in Indonesia. In the era 1970 - 2000, many water infrastructures were not sustainable in operation and maintenance. In the future, the Indonesia government would improve water services for the poor in rural areas. Therefore, research related to the sustainability of water supply systems must be conducted to contribute a problem solving in rural water supply development. Research was conducted in 24 villages of nine regencies in the Brantas River Basin, Indonesia. Result of the research is sustainability model which able to predict sustainability index. This index is used for determining level of sustainability. The level of sustainability is grouped into three levels, namely low sustainability (the sustainability index is less than 1.320), moderate sustainability (the sustainability index = 1.320 to 1.914), and high sustainability (the sustainability index is higher than 1.914). The model requires nine variables, i.e. availability of water source, selection of technology, investment cost, technical operation, institutional management, existence and ability of operator, availability of spare parts, operation cost, and community participation.
