Abstract

Municipal water supply and drainage pipe networks are core infrastructure systems that ensure the orderly operation of cities. Their level of refined design is directly related to urban water supply security, sewage treatment, and flood prevention and drainage efficiency. To adapt to the industry trend of digital transformation in municipal engineering, this paper takes BIM technology as the core research object and, based on practical scenarios in the whole-process design of municipal water supply and drainage projects, systematically reviews its practical applications in terrain modeling, forward parametric design, integrated pipeline optimization, hydraulic simulation and verification, and standardized output of design deliverables. The paper summarizes the practical difficulties in the current application of BIM technology and proposes feasible optimization strategies based on the present development of the industry, providing practical reference for digital and refined design of municipal water supply and drainage systems.
