摘要

After the decentralisation, water supply systems in several municipalities of Cochabamba department,Bolivia are being managed by different local institutions. The main aim of this study was to make acomparative evaluation of the sustainability of three water supply systems in Cochabamba, Quillacolloand Tiquipaya municipalities of Cochabamba. Based on the results of extensive field data collection andsustainability scoring system developed, technical, financial, social, institutional, and environmentalaspects of these three water supply systems were analysed. Sustainability analysis showed that SEMAPACochabamba has the highest score in all sustainability aspects followed by COAPAT Tiquipaya andEMAPAQUI Quillacolo. Furthermore, the technical aspect is the weakest in all the three water supplysystems. Lessons learnt from this study could be used to improve the sustainability of water supplysystems in these municipalities and would be helpful to analyse water supply situations in othermunicipalities in Bolivia.
