Barsha, meaning rain in Nepalese, is the name given to this hydro-powered irrigation pump. It has been developed with a vision to provide a sustainable irrigation solution to farmers across the world. This waterwheel utilizes the energy from the flow of rivers and canals to pump water, regardless of the flow velocity. The Barsha pump provides a sustainable solution to farmers across the world. It works on the principle of spiral pumping, using the kinetic energy of the waterwheel to pump water to higher elevations without the need for active mechanical parts to create pumping action. The pump consists of spirals where air is compressed between water columns resulting in air pressure that lifts the water.
