Due to the increasing importance of using clean energy, Hydrodynamic screw turbine has been considered as a small-scale hydropower source. One of the characteristics that makes the mentioned turbine to be unique compared to others is its acceptable performance in low head and flow conditions. Although a lot of research has been done in the world to achieve the best configuration to achieve the maximum output efficiency using numerical and laboratory methods, but the methods of making these types of turbines have rarely been examined. In this research, for the first time in Iran, the construction of a hydrodynamic screw turbine with a traditional method based on common industrial processes has been described. Then, its testing and evaluation have been considered. The installation angle of 24 degrees was obtained as the optimal installation angle.
