Farmers at Semera Bujurg village in the district of Lalitpur, Uttar Pradesh used to irrigate their fields using an engine pump that runs on diesel. Setup resulted in a higher expenditure of more than INR 500 Rs./day for irrigation per farmer. Sajnam River, with a width of around 200 feet flows through the Semera Bujurg village. The usage of the power available with flowing water through the river showed the potential solution to the woes of the farmers at that location. A water wheel is designed to extract the energy from flowing water through the river and is used to run a pump for irrigation. A region near the river was chosen due to its previous earthen constructions which provided resistance to flowing water. These earthen constructions were to be propped up in order to create a weir through which water can diverted for a water wheel to be installed. The calculation of the construction of the earthen–stone dam, as well as the weir, are enumerated. The design of the width of the dam and the forces on it are enumerated. Further, the flow rate through a weir of 1.5 m and opening of 2 ft of the sluice gate on the weir is also calculated. The sluice gate can be opened and closed as per requirements. Depending upon the flow rate and head available, the water wheel design is initiated. The power produced by the water wheel is calculated. Vanes are designed using the velocity triangle method. The shaft of the turbine is designed by assuming an allowable maximum shear stress of 3500 N/m2. The gear box design for the system with a 1:40 ratio was initially developed for input and output of around 40 KW. Here negligible losses are assumed in the transmission capacity of a gearbox. A commercially available self-priming centrifugal pump of 11.29 kW or 15hp was attached to the gearbox to enable water pumping requirements requested by the farmers of Semera Bujurg Village. At present the whole run-of-river water wheel setup is working continuously for the last several months on the Sajnam River, in Lalitpur, UP, and irrigating the more than 100 acres of land in Semera Bujurg Village.
