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 utilises the energy from the flow of rivers and canals to pump water, regardless of the flow velocity. Requiring no fuel or electricity to be operated means that there are no operating expenses and no polluting greenhouse gases emitted. The Barsha pump is made with indigenous elements and does not need much maintenance as there are only few moving parts. As a result of these factors, the Barsha pump can save over 70% of watering costs for farmers, compared to conventionally-used fossil-fuel based pumps.
