本研究は、コンゴ民主共和国の農村部における飲料水供給システムを比較し、重力式システムが最も持続可能で低コスト（月144ドル）であることを示した。水力タービン式は急峻な地形で有効だがコストが高く（月372ドル）、ディーゼル式は経済的・環境的に不利（月769.56ドル）である。地形条件が許せば重力式を優先すべきと提言している。
English
This study compares three water supply systems in rural DRC: gravitational, hydraulic (Kaplan turbine), and thermal (diesel generator). The gravitational system is most sustainable with low cost ($144/month) and environmental impact, while the thermal system is least favorable ($769.56/month). The study recommends prioritizing gravitational solutions where topographical conditions allow.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文はDRC固有の事例研究であり、日本のGX政策（SSBJや有報等）との直接的な接点はない。ただし、再生可能エネルギーを活用した簡易水供給システムの事例として、日本の離島や山間部での応用可能性を示唆する点で参考になる。
In the global GX context
This paper contributes to global energy transition literature by providing empirical evidence on low-tech renewable water supply systems in a developing country context. It underscores the importance of topography-driven energy choices, relevant for off-grid communities worldwide.

📄 Abstract（原文）
In a context of energy transition and limited basic energy infrastructure in the Democratic Republic of the Congo, it is relevant to conduct this study in order to encourage rural users to prioritize gravitational energy, where possible, to supply drinking water to communities facing water scarcity. This study, conducted in the Popokabaka territory in Kwango Province, aims to compare three water supply systems gravitational, hydraulic (Kaplan turbine), and thermal (diesel generator) over the period 2017 to 2025, in order to identify the most sustainable solutions for rural areas. The analysis is based on a comparative methodology integrating operating costs, standardized energy performance, and a SWOT evaluation, using data provided by technicians from user associations. For each category, a specific case was selected based on data availability, as some systems are no longer operational. The results show that the gravitational system, with a monthly cost of $144, stands out for its low environmental footprint and technical simplicity, making it the most viable option when topographical conditions are favorable. The hydraulic system represents a relevant alternative in steep areas, despite higher costs ($372/month) and greater complexity. In contrast, the thermal system appears economically and environmentally disadvantageous ($769.56/month), due to its dependence on fuel and greenhouse gas emissions. It is recommended to prioritize gravitational solutions whenever natural conditions permit and to integrate local water resources into territorial energy planning. Data availability constraints were observed, as the study was limited to Popokabaka, Kasongo-Lunda, and Kahemba. Further research is encouraged
