Pipe corrosion has close relation with microorganism vital activity in water distribution system. Biofilm commonly found on the inner walls of water distribution system play a vital role on the corrosion occurred on the surface between aqueous phase, biofilm and pipe substrate. Therefore, to study the dynamics results of structure, composition and microbial community structure in biofilm micro-environment is an important way to reveal the pipe
