The present invention relates to a system for ventilating and rehabilitating a decrepit water pipe which allows a worker to safely and efficiently perform rehabilitation work when the worker enters a pipe line to remove certain foreign substances from a decrepit inner wall of the pipe line. The system for ventilating and rehabilitating a decrepit water pipe comprises: a door assembly (3200) which is mounted on one side and the other side of a pipe line having an air supply cut unit (110) and an exhaust cut unit (120) to form a rehabilitation section, and forms an entrance; an air supply unit (1000) to control humidity and a temperature in the pipe line through the air supply cut unit of the door assembly to supply air; and an exhaust unit (2000) to purify dust in the air from inside the pipe line through the exhaust cut unit of the door assembly to discharge the air to the atmosphere. The air whose humidity is decreased by the air supply unit propagates in the pipe line, contains moisture in the pipe line and dust produced while removing a coating material, and is collected into the exhaust unit. |
