Autonomous Water Supply Solutions Operating Independent of External Power

Abstract

Access to water remains a critical challenge in rural and off-grid regions where electricity and fuel-based pumping systems are either unreliable or economically unviable. In such contexts, traditional and mechanically operated water-lifting devices offer sustainable and accessible alternatives. This paper examines two significant technologies—the Shadoof and the Archimedes' screw—which function without the need for electricity. The study provides a detailed analysis of their working principles, technical efficiency, regional adaptations, and socio-economic relevance in the Indian context. Through case studies from Bihar and Maharashtra, the research highlights how these devices contribute to improving irrigation practices, enhancing agricultural productivity, and reducing dependence on external energy sources. The paper argues that integrating traditional knowledge with modern engineering improvements can play a vital role in achieving sustainable water management and climate-resilient agriculture.
