The invention is an apparatus for thawing frozen culverts that are blocked with ice and snow. It consists of three parts A pipe or tube that is attached to the inner length of the culvert by clamps or a clamp/ bolt assembly and water tight end caps for the pipe. The pipe must me set slightly higher at the inlet end of the culvert than at the outlet end of the culvert. When the culvert becomes blocked with ice or snow and the water at the islet end of the culvert is as high as the pipe. The end caps of the pipe are removed. Water flows through the pipe and creates friction. This causes the pipe to heat up and melts the ice around the pipe. Once enough ice and snow has melted around the pipe a channel will form around the pipe through which water can flow. At this point the inlet end of the pipe should be capped and the water inside the pipe allowed to drain out. Then the outlet end of the pipe should be capped .The water flowing around the pipe will eventually melt out the rest of the ice and snow in the culvert thus clearing it.
