Water energy is essential for economic expansion and human development. Social progress and economic growth depend on meeting water energy needs sustainably. The use of non renewable energy sources for pumping water to high heads from a low head (surface flow or groundwater) has led to a global imbalance, leaving society vulnerable to an uncertain future. The thesis aims to bypass electrical energy for pumping water in a niche region of people near river basins, promoting interdependence and minimizing consumption. Technical engineering solutions applied in this work use the flow from rivers or streams as their primary input energy sources to pump 5 to 10 percent of the water needed for sustenance at higher elevations while returning 90 to 95 percent of the water that is used for pumping back to the stream. This endeavour has the potential to assist around 5% of the world's population who currently live along the river basins. The Taipadar village case study is illustrated, which is situated in the Tiriya river basin of the Chhattisgarh state, Bastar, in central-east India, to demonstrate the implementation of such technical solutions in the real world. The emphasis is given to the effectiveness of converting two hydraulic powers: input river flow and head and output delivered flow and delivery head.
