However, the high cost of SWRO technology, and its use which is quite rare in Indonesia, is the basis for the need for a study of the sustainability of SWRO technology as an alternative for clean water supply in Tanjungpinang City. This study aims is to examine the sustainability of SWRO technology in Tanjungpinang City based on social and economic sustainability aspects. To achieve this goal, several steps were taken to identify the technical and sustainability precondition of Tanjungpinang City SWRO technology carried out by descriptive analysis, identifying social sustainability based on community acceptance, public trust in water quantity and quality and willingness of people to pay for water from SWRO technology based on questionnaire primary data, cross tabulation analysis and binary logistic regression, as well as identifying the economic sustainability of SWRO technology based on desalination costs calculated by the net present value financial viability instrument. Based on this study, the result showed that Tanjungpinang City SWRO had fulfilled the technical precondition according to the literature review and related regulations, but Tanjungpinang City’s SWRO technology had not been socially and economically sustainable because the community could not accept SWRO technology as indicated by a low of community satisfaction, the quality of clean water that still low, and the community is not yet available to pay for SWRO water based predetermined tariffs and negative NPV value that lass than zero which indicates that the Tanjungpinang City SWRO is not feasible financially.
