IISc prof sets up water pumping system that needs no electricity

The efforts of a researcher at the Indian Institute of Science have resulted in villages in Chhattisgarh being equipped with a sustainable water pumping system that requires zero electricity. According to IISc, due to Mr Singh’s efforts, Taipadar is now equipped with a sustainable water pumping system that requires zero electricity. His project uses low-head check dams and cascades of such dams along rivers, with turbine pumps installed to pump water without any electricity. The turbine uses about 90% of the river water flow at low head to generate power, specifically torque and speed, which is then used to drive standard submersible multi-stage pumps.
