| Summary: | Tanjungpinang City, with its geographical problems limited raw water sources,
decrease of Pulai River Basin raw water quantity and the long distance to distribute
water from surface water sources, Tanjungpinang City Government initiated
SWRO technology as an alternative to providing clean water. 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. |
