 The calculation of the hydraulic parameters of the water flow in the drainage pipeline with the hydrodynamic method of cleaning, depending on the water flow rate of the flushing nozzle, the speed of its movement, the diameter and slope of the drainage pipeline, has been carried out. The flow rates and speeds have been determined at various stages of cleaning during the forward and reverse movement of the flushing nozzle
