The present invention relates to a method for automatic pressure control in a water pipe network and a system comprising the same and, more specifically, to an invention for maintaining a constant drip pressure by simultaneously performing automatic control of sequence and a feedback method. According to an embodiment of the present invention, in spite of fluctuations of a water pipe network and rapid demand changes, the system maintains constant drip pressure without additional modification works. Moreover, the service life of a pipe conduit is extended, and the maintenance costs of the pipe conduit and accident rates are reduced by operating an effective pressure control apparatus.
