Abstract

The quality of water supply and drainage engineering directly affects urban operation and management levels. It is necessary to apply sponge city technologies to improve the water ecological resilience of cities, thereby achieving rapid absorption and allocation of water resources, meeting urban water requirements, and promoting efficient water resource allocation. This article takes the sponge city concept as the core, elaborates on its application significance in enhancing water resource utilization efficiency, strengthening urban disaster prevention and control resilience, and optimizing the ecological environment in municipal construction. It analyzes the core principles, typical strategies, and combination logic for selecting municipal drainage technologies. Finally, it explores the design optimization of municipal water supply and drainage in road systems, pipe networks, ancillary facilities, and ecological elements, aiming to provide reference opinions for relevant designers.
