A waterway pipe using a coating waterproof agent of a nano polymer inorganic substance is provided to improve and water sealing property and durability of the pipe by preventing sulfated bacteria from being generated. A waterway pipe(1) using a coating waterproof agent of a nano polymer inorganic substance includes a waterproof layer(2). The waterproof layer is formed by the coating waterproof agent composed of an emulsive material and a powdery material inside the waterway pipe. The powdery material is composed of 30~60 weight% of cement, 20~60 weight% of a special compound, 5~10 weight% of silica nano particles, 1~5 weight% of a hardening agent, 1~3 weight% of a reactive filling material, 1~3 weight% of a reaction promoting stabilizer, 0.1~1 weight% of a high performance water-reducing agent, 0.1~1 weight% of a fungicide, and 1~30 weight% of special particles. The emulsive material is composed of 40~70 weight% of polymer, 1~2 weight% of the high performance water-reducing agent, and 20~53 weight% of water.
