Abstract
The Barsha pump is a zero energy water pump which utilises the kinetic energy of flowing river or canal water to lift water for irrigation. This has been demonstrated in Doti, Lalitpur, Jhapa and Syangja Districts. Practical Action is piloting the technology to adapt to the local situation and increase efficiency. It is a simple technology that works on the proven principle of a spiral pumping mechanism. It is propelled by the flow of streaming water using the kinetic energy to pump part of the streaming water to higher located fields without the need for active mechanical parts to create the pumping action. The pump is a simple-to-operate, low-cost solution that requires virtually no maintenance as it contains only one moving part. Due to this, it does not involve any operating expenses nor does it emit any polluting greenhouse gases and saves almost 70 per cent of irrigation cost compared to conventional irrigation methods. Practical Action has been implementing this pilot project under Securing Water For Food (SWFF): A Grand Challenge for Development Programme in partnership with aQysta B. V., a private start-up company based in the Netherlands and funded by USAID, Swedish International Development Agency (SIDA), and Ministry of foreign affairs, the Netherlands.
