PROBLEM TO BE SOLVED: To provide a method for forcibly transferring the screen residues generated at a sewage disposal plant by a piping without causing clogging. SOLUTION: In the first invention, the screen residues are forcibly transferred in the piping in a state in which the screen residues are mixed with dehydrated cake. In the second invention, the screen residues are forcibly transferred in the piping in a state in which the residues are alternately mixed with the dehydrated cake. In any case, the mixing volume ratio of the residues is kept at <=60%. In such a way, wide space required for a conveyor is eliminated.
