PROBLEM TO BE SOLVED: To make a resin part exert the chemical agent effect of a slime remover, and on the contrary, to make a metallic part reduce the chemical agent effect, in a drainage system wherein a drainage system made of a resin and a metal, or made of the resin is coated with a metallic material. SOLUTION: This drainage system with the slime remover comprises: the drainage system 4 made of the resin, or the drainage system 4 with a surface made of at least the metal, which is equipped with a drain inlet 2 for allowing the inflow of wastewater from drainage equipment 1, and a drain inlet 3 for allowing the wastewater from the drain inlet 2 to be discharged into a sewer; and the slime remover 5 which is attached to the drainage system 4. The drainage system with the slime remover is characterized in that: at least a surface of a part, where the resin is exposed, is roughened to enhance water retentivity; or graining for drawing such a pattern that water destroys surface tension by unevenness is applied to at least the surface of the metallic surface 7.
