Abstract
This is a study on assessing factors affecting sustainability of water supply system in Zanzibar Urban West Region Unguja. The study was guided by three hypotheses as predicting variables to sustainability of water supply system in Zanzibar, which were limited water infrastructures, low tariffs charged and the failure of water utility. The study was conducted using explanatory study design through causality testing approach between study variables. Data were obtained from the Zanzibar Water Authority (ZAWA) through questionnaires as the data collection tool from the selected sample size of the study. Data collected were well assembled and filled in the SPSS data sheet version 21.0 to produce adequate and relevant analytical tools to describe the entire causal relationship analysis in generating sufficient knowledge to fill the identified study gap. Descriptive statistics were first produced from the SPSS to show the profile of the respondents. Moreover, correlation and multiple regression analysis were described to show the relationship between study variables as being the independent on the dependent variable. Findings of the study showed that all three study hypotheses are positive and significant statistically on sustainability of water supply system as the dependent variable. This entails the fact that sustainability of water supply system in Zanzibar Urban West Region Unguja is negatively affected by limited water infrastructures, low tariffs charged and the failure of water utility. The study recommends that the government should be strict on assuring that it well invests on water infrastructures to match with the current demand pertaining to water supply pattern in Zanzibar Urban West Region Unguja.
