Résumé
The sustainability of groundwater equipment systems is not well addressed in the Gulf Cooperation Council Countries (GCC). The typical technology practiced in the GCC is the borehole pumps coupled with asynchronous motors. This thesis is evaluating the sustainability of various alternatives for groundwater equipment through the three pillars of sustainability. Economic assessment seeking the Levelized cost of water given typically in $/m³ and main factors affecting the energy intensity through a statistical comparative analysis approach. Environmental evaluation through performing a life cycle assessment model for four pumping alternatives, and finally, societal impact assessment aiming to identify the best practices and tradeoffs that can be made toward a sustainable resolution. As a result of the three evaluation processes, the sustainability of the different alternatives is evaluated through a sustainability index. Results of financially conservative decision, the study outcome showed that the Asynchronous Motors (ASM) option is the most sustainable followed by the Permeant Magnet Motor (PMM). The latter is an option that is moderately situated among the rest in terms of Levelized cost of water, it also showed an environmental advantage especially for the ecosystem damage and resource availability indicators. However, the opposite ranking was the result of an environmentally conservative decision. Solar option despite a great environmental advantage mainly in the human health indicators, is still a costly investment and resulted in high Levelized cost of water.
