A pipe having a dual passage to reduce an area occupied by pipes by making a sewage passage and a draining passage in one pipe. A pipe having a dual passage comprises a pair of pipe bodies(210), a partition(220), and a guide passage. The pipe bodies adhere to each other to make a dual passage in the length direction. The partition is attached in the pipe body to divide the inside of the pipe into different passages(1,2). The partition is inclined with regard to an axis of the pipe body and inclined 1m upwards every 200m or inclined 1m downwards every 200m in the length direction of the pipe. The guide passage is formed on the bottom of the pipe body in the semi-circle shape longitudinally. The guide passage is provided with a guide recess formed along the bottom center of the guide passage. |
