Culvert flushing uses high pressure water and a jet nozzle to move systematically through sections of a stormwater collection system. This creates a scouring action to clean the pipe’s inner walls and helps to remove build-up of debris and sediment. This section of pipe on 56th Place needed to be cleaned out to have proper flow during the upcoming winter rains.
