Improved Shallow TubeWell Drill Rig

Groundwater is the primary source of irrigation in Nepal’s Terai regions. Shallow tube well drilling is the traditional and standard method to pump out the water bore. However, this practice is more expensive, time-consuming, and laborious. Thus, CSISA has designed and developed a mechanical technology to drill the borewell using a power tiller, which reduces the overall costs and completes the task faster than the conventional manual method.The improved Shallow Tube Well (STW) drill rig utilizes a power tiller and thus replaces a labor-intensive conventional method. This can address the existing labor shortages and reduce the overall cost. Despite the high initial investment, the improved STW technology is: The improved STW drill rig is a power tiller-operated hammering technique where the wheel rim is placed in one shaft and works as a spool. The rope winds over the rim on one side, connected with the hammer on the other. Thus, the hammer is uplifted and released for impact by winding and unwinding the spool using the clutch lever of the power tiller. Therefore, this low-cost technology requires less labor and time compared to the conventional method.
