PURPOSE: A forming method for reinforcing a body of a sewage treatment facility is provided to improve the durability of a sewage treatment facility by increasing the shear stress thereof and to prevent soil or water contamination due to the leakage of sewage water. CONSTITUTION: A forming method for reinforcing a body of a sewage treatment facility is as follows. A FRP(Fiber Reinforced Plastic) formed layer(20) is formed in the outer peripheral surface of a sewage treatment facility mandrel forming mold(10). Filament rovings(21) are formed in a helical direction in a latticed shape and spiral filament rovings(22) are complexly formed between the filament rovings. Accordingly, FRP formed layer can be formed by repetitive works. A sewage treatment facility reinforcing unit(30) for reinforcing a sewage treatment facility is installed in the center of the FRP formed layer formed in the sewage treatment facility mandrel forming mold.
