Abstract: BIM technology provides new ideas for solving the problems of large scale, complex process, complicated pipelines and high degree of difficulty in multi-disciplinary cooperation in urban sewage treatment plants. This paper summarizes the technical advantages and existing problems of BIM technology in the design of wastewater treatment plant by combing the development of BIM technology in recent years at home and abroad and its application progress in the design of sewage treatment plant, and puts forward some suggestions for the application research of BIM technology in the design for future municipal wastewater treatment plants.
