PURPOSE: A sediment-reducing sewage pipe is provided to reduce precipitation by ascending deposits due to vortex because protrusions are separately formed along a longitudinal direction to form the internal vortex. CONSTITUTION: A sediment sewage pipe(100) comprises an arc-shaped portion(114), vertical portions(116), and a horizontal portion(118). The arc-shaped portion is formed in an inner upper part of a sewage pipe and has an arc-shaped section structure. The vertical portions are downwardly extended from both ends of the arc-shaped portion. The horizontal portion connects both ends of the vertical portions to form a bottom surface(119).
