The Water-Driven Water Lifting System (WDWLS) does not require external source of energy but a flowing stream of water to lift and transport water. It can be sustainable and economical in device comparing to other sources of irrigation. WDWLS may be beneficial for the farmers and also reduces the use of fossil fuels, and minimizes loss of time, human health and money. The prototype was installed on rivers of Kushadevi and Kavrepalanchowk. The system converts the energy of flowing water to mechanical energy, and again use the mechanical energy to lift the water to upland. Two pumps was used for the continuous flow of water. The project was successfully tested after the installation of the upgraded system.
Bibhor Shrestha, Vijay Kumar Chaudhary and Abinish Kumar Dutta, students from Department of Mechanical Engineering, Kathmandu University, prepared this prototype in 2016.
