the rod 201 and the coupling 202 may be integral or formed as separate pieces and attached together the coupling 202 may also be hollow to allow the introduction of pressurized fluids into the rod 201 one or more nozzles 204 provided at various locations on the rod 201 are in fluid communication with the channel 103 of the rod 201 to conduct pressurized fluids to aid in debris removal the rod 201 is coupled by radial supports 206 to a housing 208 the rod 201 may be coupled coaxially along a center longitudinal axis 209 to the longitudinal axis of the housing 208 the housing 208 may serve to cover and protect nozzles 204 and to keep them from becoming stopped up or clogged the tubular housing 208 may be chosen to approximately match the circular cross section of certain culverts thus allowing a thorough cleaning in one pass in some instances however with a large culvert the housing 208 may be chosen to be smaller than the interior of the culvert to allow only portion of the culvert to be cleaned with each pass in one embodiment the diameter of the housing 208 may range from about 31 inches to about 48 inches and the length from about.
