One of the main types of maintenance work in collector and drainage networks is the hydrodynamic cleaning of the interior of drainage pipes. Its disadvantage is the high cost of the work. A method for cleaning collector and drainage networks of silt using a high-speed, pressurized water flow has been proposed. Equipment for this method has been developed and field-tested.
