2. Debris Management The profile of scupper drain grating is designed with openings that allow water to pass while trapping larger particles. This design minimizes maintenance by reducing the frequency of blockages within the drainage system. Regularly cleaning the grating is sufficient to ensure optimal performance.

Urban planners and civil engineers recognize the importance of manhole covers in the broader context of city design. They are crucial in planning drainage systems to prevent flooding and manage stormwater. In heavy rainfall, well-designed drainage systems, complete with properly placed manhole covers, can help channel excess water away from streets and residential areas, reducing the risk of flooding. Thus, the strategic placement and design of manhole covers are significant components of effective urban drainage planning.
