The article analyzes the limitations of the known methods of cleaning drainage from silting. It is shown that the main disadvantage of the most common method of cleaning with a drape-washing machine is the possibility of its implementation only during low-water periods with a free drainage mouth. As a result, there is a water deficit and it is problematic to ensure sufficient speed for removing sediment due to shortage of water for washing. A new method of cleaning using high-speed pressure flow created by pumping water from the drainage cavity by the pump during the high-water period is described. Possible variations of the implementation methods are presented. The results of experimental verification of the method under production conditions are given.
