Assessing the Implications of Water Supply Technology on the Sustainability of Rural Water Supply in Dodoma Region, Tanzania
This study assessed sustainability of rural water supply projects in Bahi and Chamwino districts, Dodoma, central Tanzania. The study adopted a cross-sectional research design. In order to study different types of projects two strata were created basing on extraction methods used. A total of 24 projects were surveyed across the study area and 136 respondents were interviewed. Multiple data collection methods such as FGDs and Interviews were used. The collected data were processed and analysed using descriptive analysis method. The study found that there was very limited involvement of the beneficiaries in the decision of the type of affordable and appropriate water supply technologies. Nearly all the respondents denied to have been involved in decision on water supply technology options that would suit their needs. A majority of the surveyed projects were found to be functional; however, the remaining small fraction of 10.3% and 30.4% non functional schemes in Bahi and Chamwino respectively signified that there were some communities that did not have access to safe and clean water supply due to technical challenges caused by the chosen water supply technologies. The study established a very strong negative correlation coefficient (r = -91.99%) between the technology used and sustainability of the project. It was recommended to the external actor side that transparency should be well observed at community level thereby sharing with the beneficiaries on all the technological options, their advantages and disadvantages, and wherever possible to consider and respect technologies in which the communities have experience so as to enhance sustainability of the particular rural water supply projects.
