Municipal or urban engineering is a specialized field of civil engineering that deals with the design, construction, and maintenance of infrastructure systems in urban areas. This includes roads, bridges, water supply and sewage systems, public transportation networks, and other public facilities. Municipal engineers work closely with city planners, government agencies, and private contractors to ensure that urban infrastructure is designed and implemented to meet the needs of urban populations efficiently and sustainably. Successful municipal engineers must have a solid understanding of urban planning, environmental science, and the construction industry.
